A useful extension, not an awkward add-on

Old and new connected

We plan openings, services and finishes around the existing building.

Disruption considered

We review access and sequencing to keep the household as workable as possible.

Add space that belongs with the existing home

An extension should solve a real problem, not simply add a box to the back of the house. You may need a larger kitchen, a family area, another bedroom or a better link to the garden. We look at how the new space will work with the rooms you already use, then consider the form that suits the property.
Rear, side, wrap-around, single-storey and two-storey extensions each bring different questions around access, structure and planning. We combine dedicated technical input with construction management so those questions are addressed before site work races ahead. For projects in Barnet, we also consider how the new materials will match or complement the original building.

Plan around access, services and daily life

The usual build sequence moves from feasibility and design into groundworks, structure and weatherproofing. Services, internal finishes and final integration follow. Structural openings and altered plumbing or electrics must be planned carefully because the old and new parts of the house have to meet cleanly.
We also discuss practical disruption. Site access, temporary protection and the point when existing rooms are opened into the extension all affect how usable your home remains. Some dust will still behave as if it pays the mortgage, but organised sequencing helps keep the project and household from tripping over each other.

Frequently asked questions

Which type of house extension should we choose?

The right format depends on your property, available land, planning position and what the extra space must achieve. We can review rear, side, wrap-around, single-storey or two-storey ideas against those practical points.

Can we stay in the house during the build?

That depends on the scope, access and stage of work. We discuss temporary protection, service interruptions and when the new opening will be formed, helping you plan around periods when parts of the home may be harder to use.

Do you help with planning and technical design?

Yes. We provide dedicated planning and technical input for suitable extension projects. We connect those early decisions to structural work, services, specification and the eventual construction sequence.
