Proudly serving our community
We have been building in and around Caversham for 34 years, and most of the work we take on now comes from people who have seen a job of ours or been passed our number by a neighbour. You deal with the same team from the first visit to the final handover. Our office is in RG4, so you can sit down with us and go through drawings, costs and timings before anything is agreed. There is also a show home in RG4 you are welcome to look round.
Our services

As a construction company we handle the whole job, from home extensions and loft conversions to garage conversions and full house refurbishments. We cover Caversham, Emmer Green and Woodley. Groundworks, brickwork, roofing and finishing are all run by one team, so nobody is waiting on anybody else to turn up.

Our home builder work covers new build homes, annexe construction, barn conversions and the groundworks and foundations underneath them, across Sonning Common, Earley and Purley on Thames. We can build from your architect's drawings or help shape the design first if you are still working out what fits the plot.

As a building firm we take on kitchen refurbishments, bathroom renovations, basement conversions and garden room construction in Reading and across Berkshire. Smaller jobs get the same planning and the same site standards as a full build. Ask us to come and look, and you will get a written quote broken down by stage.

Inspection
We check everything is completed properly and you are fully satisfied.
Most single storey home extensions take around twelve to sixteen weeks on site, depending on the size and what the ground is like. Two storey work takes longer. You get a schedule before we start, so you know which weeks are groundworks, which are the shell and when the inside gets finished.
It depends on the size of the job, the finish you want and what is already there. We come out, look at the property, talk through what you have in mind and send a written quote broken down by stage. There is no charge for the visit or for the quote itself.
Yes. We work from your drawings and submit whatever the local authority for your address needs, then deal with building control inspections as the job goes on. Some extensions and loft conversions fall under permitted development and need no planning application at all. We will tell you which applies before you spend money on plans.
Yes. We have a show home in RG4 that you are welcome to look round, which is the easiest way to judge the standard of the finish for yourself. You can also call into the office in RG4 and go through drawings and past work with us before you decide anything.
