Question 1

How much does a rear extension and open-plan kitchen cost on a W6 Victorian terrace in Hammersmith?

Accepted Answer

Taking a Hammersmith terrace's ground floor out to the garden — structural steelwork, insulated roof, blockwork or brick walls, bifold or sliding glazing, and a finished kitchen behind it — typically lands between £74,000 and £112,000 in W6. The spread comes mainly from how deep the extension runs and the glazing specification. The quote we produce at the site visit separates the structural shell, glazing package, kitchen supply and kitchen installation as distinct costed lines, so you can increase or reduce any section independently before you sign anything.

Question 2

Does knocking through walls inside my Hammersmith terrace need planning permission?

Accepted Answer

Internal structural work — removing a chimney breast, taking out the wall between a front and rear room — sits under building regulations rather than planning consent. A structural engineer must size the steel, building control must inspect before and after, and if the wall you're moving adjoins a neighbouring property, a party-wall notice goes out first. On a W6 mid-terrace that typically means both sides. PSS manages the engineering coordination, serves the party-wall notices, and presents the sequence — what happens in what order and when — at the survey, before any price is agreed.

Question 3

Which Hammersmith streets sit inside a conservation area, and what does that mean for extensions?

Accepted Answer

Conservation-area designations within W6 cover the streets around Ravenscourt Park, much of the Brackenbury Village grid, and several riverside stretches. For an address inside those boundaries, external changes — a rear addition beyond a modest scale, any roof alteration, alterations to the front elevation — generally need a full planning application rather than proceeding under permitted development. The residential blocks between the Broadway and the Fulham boundary to the south are mostly outside those designations. PSS checks your specific address against Hammersmith and Fulham Council's live planning maps at the survey, and tells you plainly whether a lawful development certificate or a formal application is the right route.
