Extensions & loft conversions · Worthing, Shoreham & Hove
Got the drawings? You just need the builder.
Build & Co is a carpentry led building firm run by Rob Georgeson. Send Rob your plans and he reads them himself, then sends back a fixed price with every line itemised. The same hand picked team builds it, and the final payment stays with you until you say it is done.
What we build
Bigger homes, without moving
Big extensions are what Rob loves most, the bigger the better. Then loft conversions and full renovations. Every photo here is a real Build & Co job.
Extensions
Rear, side and wraparound extensions, annexes and garage conversions. Timber frame or block, cut and fitted by our own carpenters.
Extensions →
Loft conversions
Master suites with dormers, vaulted ceilings, beams, en suites and dressing rooms. The roof structure is carpentry, which is our trade.
Loft conversions →
Renovations
Walls out, steels in, kitchens, snugs and bespoke joinery. Full house renovations run start to finish by one man.

Quotes came back double what you can spend? Do not bin the plans.
Most homeowners Rob meets have already paid an architect, and the quotes that came back were miles over budget. Rob reads the drawings himself, not an estimator, and prices every line. If the number is too high, you can see exactly which line to lift out, and he will tell you straight whether it still works.
If they’ve got plans and haven’t got a builder, they don’t need to look any further.Rob GeorgesonOwner, Build & Co

Rob's own house, Worthing
Want to see the standard? Rob built it for himself first.
Four phases over a few years. A full renovation, a double storey timber frame extension, the garden, pool and bar, then a double storey wraparound with a garage, a self contained annex, a master suite and a gym with a balcony. Rob designed it alongside the architect.



Before you pick a builder
Come and walk round one we have finished.
Most builders show you photos. Rob will take you to a job Build & Co has finished. Walk it, meet the trades who would be in your house, and ask the family anything you like, with Rob there or without him.
- Who you meet
- The same carpenters, sparky, plumber and plasterer who would be on your job. Not whoever is free that week.
- Who you talk to
- The homeowners. Ask them how it went, what it cost against the quote, and whether they would have Rob back.
- What it costs
- Nothing. Just ask Rob when you send your drawings.
What customers say
Rob gets named in nearly every review
We couldn’t be happier with the work completed on our double garage conversion and two bedroom annexe for my elderly parents. The quality of workmanship, communication and professionalism were outstanding throughout. The team were reliable, respectful and took real pride in every aspect of the build. We were so impressed that we’ve already asked the same company to return next year to refurbish and extend our main house.Verified reviewerGarage conversion and annexe, BN43 · Checkatrade
The job turned out to be more complicated (because of the building and the way it was originally built) and Rob was really proactive with guiding us through the best way to get the job done. The work all looks amazing and has been completed before we were expecting. Everyone told us that work like this always takes longer than quoted for but it actually wasn’t in our case.Verified reviewerBN3 · Checkatrade
Rob is a great project manager who coordinated the different teams involved well. He recommended improvements to what had been planned, flagged and resolved issues as they arose. I was kept informed throughout. The work is to a high standard and I am really happy with the result.Verified reviewerLoft room, new roof, conservatory and garage conversion, BN14 · Checkatrade

Homes, and a school that trusted us with it

A bungalow going up to two storeys
The roof off, a new first floor with three bedrooms and two bathrooms, and a rear extension. Our carpenters did the timber frame and first fix, and come back for the second fix.
