The service

A new build is the purest form of what we do. A plot, a vision, and one team to carry it from the first line on the drawing to the keys in your hand.

We take on complete new homes across Surrey: single dwellings, replacement houses, self builds and small developments. From the moment the ground is broken, everything is handled in-house or by trusted trades we have worked with for years, all pulling in one direction.

You can bring your own architect and drawings, or we can introduce you to designers we know and trust. Either way, we build to the drawing, keep you informed at every stage, and hand over a home finished to a standard we are proud to put our name to.

Thirty years of building in Surrey has taught us that the best projects are the calm ones. Clear pricing, a tidy site, honest updates, and no surprises. That is how we like to work, and it is why so much of what we do comes by personal recommendation.

By the numbers

Three decades of getting it right.

We have been putting up homes in this corner of Surrey since 1996. Here is what that adds up to.

How a new build comes together

A new home builder, from bare plot to finished home.

01Groundworks and foundations being laid on a new build site in Surrey
Groundworks

From the ground up

It all begins below the surface. Site clearance, foundations, drainage and services are set out precisely, because a home is only ever as good as the ground it stands on.

  • Site clearance and setting out
  • Foundations, drainage and services
  • Building control sign off at each stage

Structure

Built to the drawing

Superstructure, steelwork, brickwork and roof. This is where the shape of your home appears, built exactly to the architect's drawings with a level of care you can see in every course of brick.

  • Structural steel and timber frame
  • Brick, block and render to specification
  • Roofing, windows and weathertight shell

Fit out & finish

Finished beautifully

First fix, second fix, plaster, kitchens, bathrooms and the fine details that make a house a home. We snag it properly, walk it with you, and only hand over when it is right.

  • Kitchens, bathrooms and joinery
  • Decoration and finishing throughout
  • Full snagging and a walk round handover
Your build, step by step

Four stages, clearly run.

You will always know which stage your home is at, what is happening next, and who is on site that week.

1

Site and foundations

We clear the plot, set out the footprint from the drawings and dig the foundations. Drainage and incoming services go in at the same time, and building control inspects before anything is covered over.

2

Structure and roof

Brick, block, steels and floors take the house up to eaves, then the roof, windows and doors go on. Once the shell is watertight the inside work carries on whatever the Surrey weather is doing.

3

First and second fix

Wiring, pipework and insulation go in first, then plastering, joinery, kitchens and bathrooms. Decoration and flooring follow once everything has been tested and signed off.

4

Snagging and handover

We snag the house ourselves before you ever see a list, then walk every room with you. You get the certificates, the warranties, the paperwork and the keys.

Before the build

What we look for on a plot.

A plot is won or lost on things you cannot see from the pavement. This is the work that happens before anybody prices a brick.

Two plots on the same road can be tens of thousands of pounds apart before a single brick is laid, and the difference is rarely the view. It is the ground, the levels, the access and where the drains run. If you are still deciding whether to buy, or you own the land and are working the scheme up with your architect, an honest look at the practical side is worth having early, while changing your mind is still cheap.

We walk the plot with you and start with the dull questions. How does a lorry get in, and where does it turn round. Is there room for a materials store, a skip and welfare, or does everything have to be delivered to order. How far does the ground fall from one corner to the other, because a fall of much more than a metre usually brings retaining, stepped foundations and a great deal more spoil to cart away. What is growing on it, since mature trees change foundation depths and some carry preservation orders. Where is the nearest public sewer, and does the plot have a water supply already or are we starting from nothing.

Then we read what comes with the land. The planning consent and every condition attached to it, restrictive covenants on the title, rights of way, shared drives, and any boundary that will need a party wall notice. Conditions are the part people skip. A consent can require materials to be approved before work starts, a construction management plan to be agreed, or an ecology survey that can only be carried out at certain times of year. Each one has a lead time. Found at the survey they cost nothing. Found in the week you hoped to start, they cost weeks.

We build right across the county, so if you are weighing up more than one site there is a fair chance we have worked in both places already. The towns and villages we cover are all listed if you want to check.

Access and space

Gate widths, turning room, overhead cables and where a lorry can safely stand. Tight access does not stop a build, but it has to be priced honestly rather than discovered.

Levels and retaining

A sloping plot means cut and fill, retaining walls and stepped footings. We survey levels properly so the earthworks are a line in the quote, not a surprise in month two.

Trees and ecology

Species, spread and distance set foundation depths on clay. Protected trees, hedgerows, bats and nesting birds all have their own rules and their own seasons.

Title and conditions

Planning conditions, covenants, rights of way and drainage easements. We read them before we price, because they decide what can be built and when it can start.

Ground conditions

What is under the plot sets the price.

Foundations are the one part of a new home nobody ever sees, and the one part nobody should ever have to think about again.

Surrey is not one kind of ground. The chalk of the North Downs behaves nothing like the London Clay to the north of it, or the Weald clay and greensand to the south, and a single plot can have made ground, an old pond or a filled pit sitting quietly under the topsoil. Clay shrinks and swells with the seasons and with whatever is growing in it, which is why foundation depths near mature trees are set by species and distance rather than by habit.

So before we price groundworks we want evidence rather than an opinion. On most plots that means trial holes dug at the corners of the footprint, so the strata and the water level can be seen rather than assumed. On anything doubtful, a site investigation with boreholes and a soil report gives the structural engineer what they need to design the foundation properly. It is a modest cost early set against a large unknown later, and the report belongs to you.

The engineer designs the foundation and building control inspects it. Our job is to build it exactly as drawn and to have the trench open when the inspector arrives. These are the types you are most likely to hear discussed.

Trench fill
The common choice on clay. A narrow trench is dug to the depth the engineer specifies and filled almost to the top with concrete. Fast, strong and simple, though the deeper the trench the more concrete it drinks.
Traditional strip
A concrete strip at the base of the trench with blockwork built off it up to floor level. It uses less concrete than trench fill but takes longer, so it tends to suit shallower, firmer ground.
Reinforced raft
A single reinforced slab that spreads the whole load of the house over a wide area. Used where the ground is soft, variable or made up, and where digging deep trenches would cause more trouble than it solves.
Piles and ground beams
Where good bearing is a long way down, or where large trees rule out digging close to the house, piles carry the load to firmer strata and a ring of reinforced beams carries the walls. The costliest option, and sometimes the only one.
Stepped footings
On a sloping plot the foundation is stepped down the fall in regular lifts. It has to be set out carefully, and it usually comes with retaining walls, drainage behind them and more spoil off site than a level plot would ever produce.
Made ground and obstructions
Old foundations, filled ponds, buried tanks and rubble all turn up on infill plots. They are dug out and replaced with engineered fill, or the foundation is redesigned to pass over them. Either way you get the reason and a written figure before we carry on.
Inspection
Building control looks at the open excavation before any concrete is poured, and again at damp proof course level. Nothing gets covered up until it has been seen, which is exactly how it should be.
Drainage and services

Drains, water and the connections.

Connections are the likeliest thing to hold up a new build, because not one of them is in your gift or ours.

Every new home needs somewhere for the foul water to go, somewhere for the rainwater to go, and a supply of electricity, water and usually gas. On a plot in an established street that can be straightforward. On a field, a paddock or the bottom of a long garden it can be the single largest variable in the job, so we get it settled early and in writing.

Foul drainage normally means a connection to the public sewer, applied for through the water company. If a public sewer already crosses the plot, a build over or divert agreement has to be in place before anything is built near it, and that takes time. Where there is no sewer within reach, a package treatment plant or a septic tank is designed to suit the number of bedrooms and the way the outfall discharges, in line with the general binding rules for the site.

Rainwater is kept separate. The order of preference is to soak it away on the plot, then to a watercourse, and only as a last resort to a sewer. A soakaway is sized from a percolation test rather than a guess, because clay that will not take water makes a well built soakaway useless. Where the ground will not soak, we look at attenuation, a controlled discharge, permeable paving or land drainage, and the planning conditions on the consent often decide it for us.

The utility applications go in at the very start of the job. Each one goes to a different organisation, each has its own lead time and its own charge, and those charges are quoted by the provider and paid to them rather than to us. Getting the applications away in week one is the cheapest thing anybody does on a new build.

Foul drainage

  • Sewer connection applied for through the water company
  • Build over or divert agreement where a sewer crosses the plot
  • Inspection chambers set where they can be reached later
  • Falls and pipe sizes to the engineer's drainage layout
  • Package treatment plant or septic tank on off mains plots
  • Drains tested and inspected before the trench is backfilled

Surface water

  • Soakaways sized from a percolation test on the plot
  • Attenuation or a controlled discharge where clay will not take it
  • Permeable driveways and paving where planning asks for them
  • Land drainage on wet plots or ground falling towards the house
  • Gutters, downpipes and gullies sized for the roof area
  • Rainwater kept out of the foul system, which is a requirement

Utility connections

  • Electricity supply applied for through the network operator
  • A temporary builder's supply so the site is not run on generators
  • Water main connection with the meter position agreed
  • Gas connection where the house is not all electric
  • Broadband ducting laid while the trenches are still open
  • Connection charges quoted and paid to each provider direct
  • Applications made in week one, because lead times run to months
Warranty and sign off

The paperwork that makes it a house you can sell.

A new home is only finished when the certificates are in your hands. Here is what they are and who issues them.

Building control

Building control is the approval that says the house meets the building regulations, and it is entirely separate from planning permission. It is handled either by the local authority or by a registered building control approver, and the inspections come at set points: the open excavation, the foundation, the damp proof course, the drains before backfilling, the structure, the insulation and air tightness, and then completion. We book those visits, we meet the inspector on site ourselves, and we do not cover up work that has not been seen. At the end you get a completion certificate, and your solicitor will ask for it the first time you sell or remortgage.

Structural warranty

A new home normally carries a ten year structural warranty from a recognised provider. The first couple of years cover defects, and the remaining years cover the structure itself. Mortgage lenders expect to see one, and so does the solicitor acting for anybody who buys the house from you inside that ten year window. The timing matters more than people expect. A warranty has to be registered with the provider before work starts, because the provider carries out its own stage inspections as the building goes up and will not insure what it never saw. We raise it at the first meeting rather than halfway through the groundworks.

Testing and certificates

A new house in England is also tested. There is an air tightness test on the finished shell, energy calculations that produce the EPC, ventilation that has to be commissioned and recorded, overheating and water efficiency to satisfy, and a charging point provision for an electric car. Add to that the electrical installation certificate, the gas safety and commissioning paperwork, the unvented cylinder certificate and the manufacturer registrations for the heating. We collect the lot into one file and hand it over with the keys, because in ten years time that folder is worth having.

The programme in detail

What a new build looks like, stage by stage.

The same four stages set out earlier, opened up into the eight blocks of work a programme is actually built from.

Every plot runs slightly differently, but the order almost never changes, and knowing the order tells you what your money is buying in any given month. Photographs of these stages on real Surrey sites are on our recent work page if you would rather see it than read it.

01

Pre start

Nothing visible happens and a great deal gets done. Structural calculations and the foundation design are finalised, building control is appointed and notified, the warranty is registered, utility applications go in, party wall notices are served where a boundary needs them, and the programme and payment stages are agreed in writing.

02

Site set up and enabling

Hoarding or fencing, welfare, a temporary supply, a store and a safe route in for deliveries. Then site clearance, any tree work already agreed, and the topsoil stripped and stacked. The footprint is set out from the drawings and checked before anything is dug.

03

Groundworks and foundations

Excavation, inspection of the open trench, concrete, and blockwork up to damp proof course level. Below ground drainage is laid and tested at the same time, and the ground floor slab or beam and block floor goes in with its insulation and membranes.

04

Superstructure

The walls go up in brick and block or timber frame, with steels, lintels, cavity insulation and wall ties as specified. Floor joists go in at first floor level, scaffolding rises with the build, and by the end of this stage the shape of the house is finally on the plot.

05

Roof and weathertight

Roof structure, felt, battens and tiles, then fascias, gutters and downpipes. Windows and external doors follow, and the moment the last one is in, the house is weathertight and the inside work stops caring what the Surrey weather is doing.

06

First fix and plaster

Wiring, pipework, waste runs, heating, ventilation and any underfloor pipework, followed by insulation, stud walls and boarding. Building control looks at the insulation and services before they are hidden, and then the house is plastered and left to dry.

07

Second fix and finishes

Screeds and floors, joinery, staircase, doors and skirtings, kitchen, bathrooms, sanitaryware, sockets, switches, lights and the heating brought to life. Tiling, decoration and the fine details follow in a set order so nothing finished gets walked over twice.

08

External works, testing and handover

Drives, paths, patios, boundaries and planting outside while the air test, commissioning and final inspections are carried out inside. We snag the house ourselves, put it right, then walk every room with you and hand over the keys, the certificates and the file.

What a quote covers

What is included, and what is not.

Two quotes for the same house can be far apart simply because one of them left things out. This is how ours is built up.

Our quotation is for the building work: everything needed to take your approved drawings and turn them into a finished, tested, signed off house. It is written out stage by stage so you can see where the money sits, and anything we have assumed or left out is written down as an assumption or an exclusion rather than left for you to find later. Where a kitchen, sanitaryware or flooring has not been chosen yet, we put a clearly labelled allowance in and adjust it once you have picked, up or down.

If you are comparing our figure against somebody else's, read our guide on how to choose a builder in Surrey before you decide. It sets out what a quotation should contain before it can be compared fairly, how staged payments ought to be structured, and the checks worth making on any firm before you let them start. Twenty minutes there tends to save a lot of money later. The rest of our homeowner guides cover costs, planning permission and loft conversions in the same plain terms.

In the figure

Included
  • Site set up, welfare, fencing, scaffolding, skips and insurance
  • Groundworks, foundations, below ground drainage and the ground floor
  • Structure, steelwork, roof, windows and external doors
  • First and second fix electrics, plumbing, heating and ventilation
  • Plastering, joinery, tiling, decoration and fitting the kitchen and bathrooms
  • Building control inspections, testing, commissioning and certificates
  • Our own snagging, a builder's clean and the handover walk round

Outside the figure

Not included
  • The land itself, your finance costs and legal fees
  • Design fees, structural engineering, surveys and planning application fees
  • Building control charges and the structural warranty premium
  • Utility connection charges, which are quoted and paid to each provider
  • Community Infrastructure Levy or planning contributions where the council applies them
  • Appliances, furniture, blinds and anything above a stated allowance
  • Landscaping beyond the areas named in the specification

Two things worth knowing about the money. First, work that cannot be foreseen, which on a new build almost always means the ground, is handled as a written variation before it is carried out, with the cost and the effect on the programme set out so you can decide. Second, building a new dwelling is treated differently to extending an existing one for VAT purposes, and in many cases a contractor's work on a genuinely new home is zero rated. It is worth confirming your own position with your accountant or with HMRC early, because it changes the budget noticeably.

As a rough test of whether a budget is realistic, new build work in Surrey is commonly discussed somewhere in the region of £2,400 to £3,400 per square metre for the building work alone, with higher specification homes sitting above that and simple, straightforward shapes below it. That is general market guidance rather than our price list, and it takes no account of your ground, your access or your drawings. A real figure for your plot follows a site visit and a written quotation.

Realistic timescales

How long a new build actually takes.

General ranges, not promises. Size, access, ground conditions and planning move every one of them.

People usually ask about time on site, but the calendar starts long before that. Design and planning are the slowest part of most new builds and the part a builder has least control over. The figures below are the ranges we see on ordinary Surrey plots, and some of the stages overlap in practice, so adding them all up gives you a longer answer than reality.

Design and planning
Roughly three to nine months from first sketch to a consent you can build from, longer if the site is sensitive or an application has to go back in. This sits with your architect and the council rather than with us.
Pre start
Roughly six to twelve weeks for structural design, building control, warranty registration, utility applications and party wall notices. Much of it runs alongside the tail end of planning, which is why we start it early.
Groundworks and foundations
Roughly three to eight weeks on a straightforward plot. Deep foundations, piling, retaining walls, heavy muck away or a wet winter dig can push this well beyond the top of that range.
Superstructure and roof
Roughly eight to sixteen weeks to take the house from floor level to weathertight, depending on size, storeys, the complexity of the roof and how quickly windows are delivered.
First fix and plaster
Roughly six to ten weeks, including drying out time after plastering. Rushing this stage is how floors and joinery get spoiled later, so we do not.
Second fix and finishes
Roughly eight to fourteen weeks for joinery, kitchen, bathrooms, tiling, decoration and flooring. Lead times on kitchens, stone and specialist glazing are the usual reason this stretches.
External works and handover
Roughly two to six weeks for drives, paths, patios, boundaries and planting, with testing, commissioning, final inspection and snagging alongside.
A whole house, on site
A modest three bedroom detached house on a level plot with decent access commonly runs to nine to twelve months on site. A larger or higher specification home is more often twelve to eighteen months. Difficult ground, a tight site, a winter start or changes made after work begins all push it out.

What you get from us is a programme written for your house rather than a range copied off a page, and an update every week telling you what has been done, what is next and whether anything has moved. If something slips, you hear it from us first. A realistic date and a written quotation both follow a visit to the plot, and that visit costs you nothing.

From start to finish I.C Developments were amazing. We love our new home and have passed your details on to our neighbours.

Good to know

New build questions.

Do you work with our own architect?
Absolutely. Many of our clients come to us with drawings already in hand, and we build to them. If you do not have an architect yet, we can introduce you to designers we know and trust, and manage the whole thing for you.
Can you help with planning and building control?
Yes. We coordinate structural engineering, building regulations and inspections as part of the service, and keep everything signed off at the right stages so there are no hold ups later.
How long does a new build take?
Every home is different, but most new builds run from several months to around a year depending on size and specification. We give you a realistic programme at the start and keep you updated as we go.
Do you take on self builds and replacement dwellings?
We do. Single homes, self builds, replacement houses and small developments are all part of what we do across Surrey.
Where do you build?
We are based in Reigate and build across Surrey, including Caterham, Oxted, Banstead, Epsom, Horley, Godstone and the surrounding villages. If you are just outside, ask us anyway.
Do we need a structural warranty on a new build?
In practice, yes. A ten year structural warranty is what a mortgage lender expects to see, and what the solicitor acting for any buyer will ask for if you sell inside that ten year window. The part people get caught out by is timing. A warranty has to be registered with the provider before work starts, because the provider inspects the house at stages as it goes up and will not insure what it never saw. We raise it at the first meeting rather than halfway through the groundworks.
What happens if you find bad ground once you have started?
We try hard to find it before we start, which is why we dig trial holes and, on anything doubtful, ask for a soil report before we price the groundworks. If the engineer then has to change the foundation design because what is down there is worse than the evidence showed, that is a variation and we price it in writing before anybody digs any deeper. You see the reason, the cost and the effect on the programme, and you decide. What we do not do is bury it in the next invoice.
Can you build on a plot with no mains drainage or services?
Yes, although it changes the programme rather than the design. Off mains foul drainage usually means a package treatment plant or a septic tank, sized for the house and discharged in line with the general binding rules, with the outfall agreed before anything is installed. For services, each application goes to a different organisation with its own lead time and its own charge, so we apply for electricity, water, gas and broadband in the first week of the job rather than when the house is plastered.
