    Building an Extension in Battersea

    Conservation Areas

    Battersea includes several conservation areas and two Article 4 cottage estates. We check the address and planning history before assuming permitted development applies.

    Period Properties

    A period extension needs a structural plan, drainage review and a daylight strategy that work with the original house. Our nearby Wandsworth and Clapham projects show this approach in practice.

    Party Wall Act

    Work to shared walls or foundations close to a neighbouring structure may require Party Wall Act notices. We coordinate our drawings and construction information with the appointed surveyor.

    Local Logistics

    A skip or scaffold on the public highway needs a Wandsworth licence, and controlled parking bays may need suspension. These constraints are included in the site plan and programme.

    Our Work Near Battersea

    We don't have a published extension in Battersea itself yet, so these are our nearest completed projects. Each one links to the full write-up with photos.

    How a extension with us runs

    1. Step 1

      Free site visit

      We visit, measure up and assess the existing structure, access and any party wall implications, then explain the practical next steps. No obligation.

    2. Step 2

      Fixed-price quote

      An itemised quote for the build, excluding VAT and professional fees (design, structural engineer, Building Control, party wall and planning fees), which are quoted separately.

    3. Step 3

      Approvals

      Working with your architect, the drawings are developed and submitted for planning if required, and party wall notices are served to neighbours if needed. We plan the start date around them.

    4. Step 4

      Build

      The programme is set out before work starts. If you change the scope, we price the change and agree it with you first.

    5. Step 5

      Handover

      Final inspection, a snagging walk-through with you, and keys handed over.

    Frequently Asked Questions

    It depends on the address, the original house and the proposal. Conservation areas and Article 4 Directions can remove permitted-development rights, and the Latchmere Estate direction specifically includes extensions. We check the address and planning history before recommending a route.

    Allow time before that for design, any planning or prior approval decision and party wall notices. Your programme depends on the size, structure and approvals, and we set it out in writing before work starts.

    A typical kitchen or side return extension costs about £90,000–£100,000 to build, excluding VAT and professional fees. That's the build price; kitchen units, flooring and other second-fix items are supplied by you. Access and logistics can affect the final figure, and you get a fixed quote after a site visit.

    Many terraced and semi-detached projects require notices under the Party Wall Act, but it depends on the foundations and work to shared structures. We provide the construction information and coordinate with the appointed surveyor; the surveyor handles the statutory notices and any award.
