house extensions

House extension builders for single and double storey projects

The house has worked for years, almost. Then the family grows, someone takes up working from home, and the kitchen table starts doubling as an office, a homework desk and a dining table. That is usually the point where people start looking for house extension builders, rather than putting the house on the market.


Picture it finished: a kitchen-diner that opens onto the garden, a proper utility room instead of a cupboard stuffed with coats, or a ground floor office with a door that actually closes. Upstairs, perhaps a bedroom and bathroom added above a single storey build, so everyone finally has their own space again.

How the project comes together

We coordinate every stage of a single or double storey extension, from groundworks and foundations through brickwork and blockwork, roofing, guttering, fascias and soffits, to the windows and doors that tie it into the existing house. Plumbing, heating, electrics, plastering and decorating are handled by the same team, so the finishing work matches the structural work rather than being an afterthought. As a family-run business, Sheldon Hill and his brother lead the in-house team, bringing in trusted subcontractors for the parts of the job that need them.

Deciding what to build

Some extensions are straightforward, a single storey addition across the back of the house. Others go further, adding a second floor, or exploring a wooden extension on the house for a different look and feel. If you are still gathering house extension ideas, UK homes offer plenty of approaches, from glazed garden rooms to more traditional brick additions, and we can talk through what suits your house and your budget before any work starts.

Frequently Asked Questions

  • Do I need planning permission for a house extension?

    Planning permission depends on the size and style of your extension, and whether permitted development rights apply to your property. It is usually one of the first things we talk through with you before drawing up a plan, since the rules can vary depending on your situation.

  • Will a single storey extension look like it was always part of the house?

    We aim to make an extension look and feel like part of the original house, matching brickwork, rooflines and finishes where we can. Because we coordinate groundworks, brickwork, roofing and finishing under one team, it is easier to keep everything consistent.

  • How long does a house extension usually take?

    It depends on the scope, a single storey extension generally takes less time than a double storey one with more structural work involved. We will give you a realistic timeframe once we know the size and design you have in mind.

  • Can we stay living at home while the extension is built?

    Many people do stay in the house while work goes on, though it depends on which rooms are affected and how the build is sequenced. We talk through what to expect at the planning stage so there are no surprises once work starts.

  • Who carries out the plumbing and electrical work on an extension?

    The plumbing, heating and electrical work is carried out as part of the same coordinated project, using our in-house team and trusted subcontractors for each trade. Everything is planned so the new services connect properly with the rest of the house.
