Single-Storey Rear Extensions
Add ground-floor space from the rear, often for kitchens, dining areas or larger living spaces.
When the existing layout no longer gives you the space you need, extending the property can create room for the way you want to live now.
A&B works on residential extension projects ranging from additional kitchen and dining space to larger living areas, utility rooms, home offices, bedrooms and wider property alterations.
Create additional room around the existing property.
Help the new space work with the existing layout.
Consider how the household will use the finished space.
The new construction should work practically with the existing home and its layout.
Different properties offer different possibilities. The right approach depends on the existing home, available space and the proposed use of the extension.
Add ground-floor space from the rear, often for kitchens, dining areas or larger living spaces.
Use available space beside the existing house where the property and proposed design allow.
Make better use of narrower side space and increase the usable ground-floor footprint.
Combine rear and side extension space where the property, design and relevant permissions allow.
Create additional accommodation across more than one floor, subject to the property and required approvals.
Consider the extension around the existing property, available space and individual project requirements.
Every extension is different, but the construction process can involve several connected stages from the groundwork through to the final internal finish.
Preparing the agreed working area, excavation, foundations and the early construction stages required for the proposed extension.
Walls, structural openings, specified steels and other structural components required by the agreed design and technical information.
Creating the external envelope of the extension, including roofing and the agreed window and external door openings.
Partitioning, plastering and internal building work required to connect the new space with the existing property.
Coordinating relevant electrical, plumbing, heating and other trade work where included within the agreed project specification.
Completing agreed flooring, decorating, joinery and other finishing stages according to the project scope.
The final scope will depend on the property, drawings, structural information and agreed project specification.

A few common questions homeowners ask when considering a house extension in Barnet and North London.
Not every extension requires a full planning application. Some projects may fall within permitted development rights, while others may require planning permission or prior approval. The position should be checked for the individual property before construction begins.
Depending on the property and agreed scope, projects can include rear extensions, side extensions, side-return extensions, wrap-around extensions, double-storey extensions and other residential additions.
The cost depends on factors such as the size, structure, access, specification, glazing, internal finishes and condition of the existing property. A quote should therefore be based on the individual project.
The programme varies according to the size and complexity of the extension, structural work, project specification and site conditions. A project-specific programme can be discussed once the proposed scope is sufficiently defined.
