Extensions, loft conversions, refurbishments, kitchens and bathrooms, new builds and period restoration across Merstham and the villages around it. One team, from the first survey to the last coat of paint.
Merstham is really two villages in one. The old lanes around Quality Street, and the streets that grew up after the war. We build in both.
Merstham sits at the top of the borough, north of Redhill, where the last of the town gives out and the chalk of the North Downs takes over. The M25 crosses just above the village at junction 8 and the M23 peels away beside it, which makes it one of the easiest places in Surrey to reach and one of the trickier ones to build in quietly. We have been working in and around this village for years from our base a few minutes down the road in Reigate, so we know the streets, the ground and the people who sign things off.
The housing here is unusually varied for a village of its size. The historic core along Quality Street holds listed and period cottages, tile hung and timber framed, sat behind low walls on a lane that has barely changed shape in a century. Around the church and the old high street there are Victorian and Edwardian cottages. Then, spreading south and east, there is the large 1950s Merstham estate, laid out after the war with generous plots, wide verges and solid brick and render houses. Add the interwar semis near the station and the bigger detached homes climbing Rockshaw Road onto the downs, and you have four or five entirely different building jobs inside one postcode.
That variety is the reason we like working here. A 1950s estate house is a gift for an extension or a loft conversion. The plots are deep, the rooflines are simple, and there is normally room to go out the back and up into the roof without upsetting anybody. The interwar semis around Frenches Road and Albury Road usually want the same thing that Surrey semis everywhere want, which is the back opened up into one bright kitchen and dining room with proper glazing onto the garden. The period cottages closer to Quality Street want the opposite approach, which is patience, lime mortar and repair before replacement.
The ground deserves a mention too, because Merstham is not ordinary digging. This is chalk and firestone country, and the village was quarried and mined for building stone long before it was a commuter village. Parts of it have old workings underneath, and the land rises steeply towards the downs, so plots can slope more than they look on a drawing. None of that stops good work happening, but it does mean we would rather spend a day on trial holes and a proper site investigation than guess at a foundation and find out the hard way.
Planning here goes through Reigate and Banstead Borough Council, and there is a conservation area covering the historic heart of the village around Quality Street. Green Belt and the protected downland landscape sit right on the doorstep to the north and west, at Gatton, Alderstead Heath and up towards Chipstead. All of that shapes what will and will not get through, and we would rather tell you that at the kitchen table on the first visit than let you find out six months and one refusal later. We work alongside architects and designers, and if you do not have one, we can introduce you to people we trust.
Whatever the job, it is the same firm from the first drawing to the final handover. Here is what that looks like on a Merstham street.
01Infill plots, replacement dwellings and self builds around Merstham, including the sloping sites towards Rockshaw Road and the downs where the groundworks matter as much as the house.

02The deep plots on the 1950s estate and the interwar semis near the station take a rear or wraparound extension beautifully. Matched brick, matched mortar, and a roofline that sits right.

03Post war Merstham houses are solid but dated. We take them back to brick where it is needed, rewire, replumb, insulate and rethink the layout so the house works the way you live now.
Explore refurbishments
04Simple pitched roofs and good head height make many Merstham semis straightforward to convert. A bedroom and en suite in the roof for a fraction of what moving up the road would cost.

05Whether it is a new kitchen inside an extension or a tired family bathroom stripped and started again, we handle the building work, the services and the fit out as one job.

06The cottages around Quality Street and the older houses near the church need lime mortar, salvaged brick and slow, careful hands. Repair first, replace only where there is no honest alternative.
