Builders in Horley

Horley has grown in layers, and you can read every one of them from the pavement. That is exactly what makes building here interesting.

We are a Reigate design and build company, based at 49 Vogan Close in RH2, and Horley is one of the towns we know best. It is a straight run down the A217 and the A23, twenty minutes on a normal morning, and it sits inside the same borough as our own yard. That matters more than it sounds. The planning department, the building control team and the local plan policies are the ones we deal with week in and week out, so nothing about a Horley job is unfamiliar territory for us. We have been building since 1996, and a good share of the work we take on here still comes through a neighbour who watched us finish the last one.

The housing stock is unusually varied for a town this size, and the type of house tends to decide the type of job. Around the station and along Victoria Road, Massetts Road and Albert Road you find Victorian and Edwardian cottages and terraces, often narrow fronted, with solid brick walls, no cavity and a side alley that a wide machine will never get down. Push out along Brighton Road, Lumley Road and Balcombe Road and it turns into inter war semis and detached houses on generous plots, which are close to ideal for a rear or wraparound extension. The post war estates on the eastern and southern edges of the town give you the classic loft conversion and side return opportunities. And then there is everything built in the last decade or so at Westvale Park to the west and Horley North East around Langshott, where the houses are sound and well insulated but the rooms are often smaller than a growing family wants, so the work is usually about reconfiguring rather than repairing.

Planning here goes through Reigate and Banstead Borough Council, and the answer is rarely the same twice. Plenty of single storey rear extensions in Horley sit comfortably inside permitted development, which is quicker and cheaper. But those rights are commonly restricted on newer estates where the original consent removed them, they do not apply to flats, and they thin out in the oldest part of town around St Bartholomew's Church and Church Road, where listed buildings and conservation constraints are most likely to bite. We check what actually applies to your address before anyone puts a pen to paper, because finding out three weeks into a design is an expensive way to learn.

The other thing that makes Horley different from the rest of Surrey is the airport on its doorstep. Gatwick sits immediately south of the town, and aerodrome safeguarding means the airport gets consulted on some applications, particularly anything tall, anything involving a crane, and anything that creates open water and could attract birds. Aircraft noise can also shape a scheme, most often through the glazing and ventilation specification on new bedrooms and living rooms, so the acoustic performance of a window becomes a real design decision rather than a line on an invoice. None of this stops good work getting built. It just needs raising on the first visit, which is what we do.

Below ground, Horley sits low and flat on Weald Clay, with the River Mole and the Burstow Stream running through it, so parts of the town carry a flood risk and much of it has ground that shrinks and swells with the seasons. Both affect foundations, drainage and the way surface water has to be dealt with. We survey the ground properly, dig to the depth the conditions and any nearby trees demand, and design the drainage so the finished job does not push a problem onto next door. On the narrower Victorian roads we plan the muck away and the deliveries in advance rather than assuming a lorry can simply turn up.

We are a design and build company, which means one team and one point of contact from the first survey through to handover. We work alongside architects, designers and structural engineers rather than employing them, so you get people who are genuinely good at their part of it while we run the whole thing. Groundworks, structure, first fix, second fix and finishes all sit with us. That is what we mean by from the soil in the ground to the keys in your hand.

What we do here

Six services, one local team.

Every one of these runs out of our Reigate base and covers the whole of RH6. Whatever the job turns out to be, the same people see it through from survey to handover.

Why us

Why homeowners in Horley choose us.

Six honest reasons, none of them about being the cheapest quote through the door.

Good to know

Horley questions.

Do I need planning permission for an extension in Horley?
Often you do not. A good many single storey rear extensions in Horley fall under permitted development, which is quicker and cheaper than a full application, and the wider plots on the inter war roads and the post war estates give you room to work with. Those rights are reduced or removed on some properties though, including flats, houses where an earlier consent restricted them, and the older, more sensitive corners of the town. Reigate and Banstead Borough Council is the planning authority for the whole of RH6. We check what applies to your address before anyone starts drawing, tell you honestly which route you are on, and handle the application either way.
Does being so close to Gatwick affect building work in Horley?
It can, and it is worth knowing early. The airport sits immediately south of the town, so parts of Horley fall inside aerodrome safeguarding. That means the airport is consulted on things like tall structures, cranes, lighting and anything that might attract birds, such as new ponds or open water. Aircraft noise shapes some schemes too, particularly the glazing and ventilation specification for new bedrooms and living rooms. None of it stops good work happening. It simply needs picking up at the design stage rather than being discovered halfway through, and we raise it on the first visit.
Our house is one of the older properties near Church Road. Can you still work on it?
Yes. The oldest part of Horley, around St Bartholomew's Church and the lanes near it, is where conservation designations and listed buildings are most likely to apply, so we check the council records for your address rather than assume. Where a property is protected, the design is led by what the setting will accept. Materials, window styles, roof detailing and anything visible from the road all get looked at closely, and permitted development rights may be reduced. We work alongside your architect or designer to put forward something the council will support, then build it in matching brick, the right mortar and the right detail.
Where will your team park, and how will materials get in?
We sort that out before we start. On the newer roads at Westvale Park and Langshott there is usually driveway space and reasonable turning room for a delivery lorry, but the Victorian streets near the station are tighter, with parking along both sides and narrow side alleys. We book deliveries for quieter parts of the day, keep skip and grab lorry visits to a minimum, arrange a permit or a short road closure when one is needed, and sweep the road at the end of each day. We also introduce ourselves to your immediate neighbours before the first load arrives.
How long will the work take, and do you handle building control?
A kitchen or bathroom refit is usually a matter of weeks. A single storey extension tends to run from around two to four months on site, a loft conversion something similar, and a full refurbishment or a new build considerably longer. Planning and building control add time before anyone lifts a shovel. We handle building control for you, whether that goes through Reigate and Banstead or an approved inspector. We book the inspections, meet the inspector on site at each stage and hand you the completed certificates at the end, which matters a great deal when you come to sell or remortgage.
Do you cover the villages around Horley?
We do. Smallfield, Burstow, Horne, Charlwood, Hookwood, Norwood Hill and Povey Cross are all RH6 and only a few minutes from the town, and we work up through Salfords, Sidlow and Meath Green into Redhill and Reigate as well. Our base is at Vogan Close in Reigate, a short run up the A23 and the A217, so being local is not a claim we have to stretch.
