Rear kitchen extension
Project description | Lewisham SE13 rear kitchen extension
Rear storey extension, garage conversion and internal alterations to a single family dwelling
Architectural services
Initial home consultation, measured survey and production of existing set of drawings, planning stage design and submission, Building Regulations design and submission, obtaining local authority approvals and redesign of kitchen area.
Project summary
Single storey rear kitchen extension that mirrored the adjacent existing extension along the boundary line. We aimed to create an enlarged kitchen, dining and living area that opened up to the rear garden through full height aluminium framed double glazed sliding folding doors, corner glazing, and additional rooflight glazing to bring natural light deeper in the kitchen and dining spaces. As part of our proposals we also converted the existing garage to create a new guest bedroom. Refurbishment and internal first floor alterations.
Design matters
70s retro + contemporary feel, fresh, clean, light and in dialogue with the character of the existing property in terms of scale, materials and textures. Rear extension that opens up to the rear garden in a non-linear way and in a way that allows the landscaping to become part of the internal kitchen and dining areas.
Flooring: Coloured rubber flooring. Key advantages – cost effective, warm and soft underfoot, long-lasting, easy to clean as it does not require special cleaning, also consider this type of flooring if you are an allergy sufferer, since it is very hygienic.
Budget and project costs
In the region of £100K to include construction and design, approval costs. At the moment costs are much higher due to shortages of labour and materials still. For a project of this type you should typically be budgeting the following as minimum to include supply and installation of standard glazing, standard white electrical fittings. Extensions (approx): £2,500 per sqm. Loft conversion (approx): £1,750 per sqm. Refurbishments (approx): £700 per sqm. Paving (includes supply of sub base and concrete slab, prep works and installation of client supplied pavers) approx : £115 per sqm.

This project was published in Build It magazine in February 2023, Kitchen Diner Extension Ideas by Lucy Keech.
“Want to add extra space and value to your home? A multifunctional extension could be the best way to do it, says Lucy Keech.
The main advantage of a kitchen-diner extension is to maximise the space, whether that’s for day-to-day living or for a multi-purpose area for entertaining and enjoying family time. It will encourage a better connection between the interior and the exterior too. What’s more, it will add value to your home – atypical kitchen-diner can boost sale price by up to 10%.” Read more…
