Residential and commercial construction handled from design through to completion, across Horsham and the surrounding West Sussex towns.
Most of what we do is extending a house, converting a garage or a loft, replacing a kitchen, or rebuilding a bathroom. Each has its own page below setting out what the work actually involves: the order it happens in, which permissions apply, and the decisions that are cheap to make early and expensive to change later.
Alongside that we take on commercial fit-out, structural alterations, flooring and general building work. If your project does not fit neatly into a category, it is still worth a conversation. Most jobs are a mix.

Commercial work is usually as much about scheduling as building. On a recent 6,000 sq ft warehouse conversion the business stayed open throughout, with the disruptive work moved to weekends so there was no trading downtime. In Dartford, we formed new rooms inside a working warehouse with no downtime and no dust reaching the client's operation.

Carter Cook provided an excellent service when converting our 6000sq ft warehouse in Greenhithe. All the work was completed whilst the business continued to operate and there was no downtime. Project was delivered on time, in fact 2 days earlier than planned and bang on budget.
