What a Single Storey Extension Adds

Most people build out at the back to get one bigger room instead of two small ones. A kitchen diner, a family room or a downstairs shower room are the common choices. It costs less than moving house and you keep the street, the schools and the neighbours you already have.

More Information

Do You Need Planning Permission?

A lot of rear extensions are allowed under permitted development, which means no full planning application. Depth, height and how close you build to the boundary all count. Flats, listed buildings and some estates are different. We tell you which rules look like they apply to your house before you spend anything.

How Long a Single Storey Extension Takes

Ten to sixteen weeks is normal for most homes. Footings and brickwork come first, then the roof and windows to make it watertight. After that it is first fix, plastering, second fix and decorating. Bad weather and building control visits can move dates, so we keep you posted each week.

Frequently Asked Questions

How much does a single storey extension cost in Chatham?

Cost follows the floor area, the ground conditions under the footings, the roof type and how you finish it inside. Bifold doors and a high spec kitchen push it up quickly. We measure up on site and give you a free written quote broken into stages so you can see what each part costs.

Can we stay in the house during an extension in Chatham?

Most people do. The new build goes up outside the existing wall, so the house stays usable until we break through, which is near the end. Expect noise, dust and less garden while the work runs. We sheet up, board off openings and keep the site tidy at the end of each day.

Do I need drawings for an extension in Medway?

Yes, in almost every case. Building control wants drawings showing the structure, insulation and drainage, and a structural engineer may be needed for beams. We can point you to draughtsmen we work with regularly, or price the build from drawings you already have.
