Question 1

How much should I budget for a side-return extension and kitchen refit on a Victorian terrace in Hammersmith and Fulham?

Accepted Answer

A side-return infill combined with a full kitchen replacement typically runs from £72,000 to £110,000 on Victorian stock across W6, W12, W14, and SW6. Width varies parcel by parcel — some Fulham side returns yield barely a metre of usable gain; others in West Kensington add a genuine new bay. Cost drivers include structural steelwork, rooflights, underfloor heating, and kitchen supply grade. Party-wall fees and a structural engineer's calculations are broken out as distinct line items in the quote PrimeCraft prepares on the day of the survey.

Question 2

Which conservation areas in Hammersmith and Fulham restrict what I can do without a planning application?

Accepted Answer

Hammersmith and Fulham has over thirty conservation area designations. In W6 the Brackenbury Village and Ravenscourt Park areas cover dense terrace grids where external alterations — dormers, flat-roof additions, and render — need full planning consent. In SW6, the Walham Green, Sands End, and New Kings Road designations carry similar controls. Parts of W14 around Barons Court fall within the Brook Green conservation area. Work that stays entirely internal — structural reconfigurations, kitchen and bathroom renovations — is unaffected by those boundaries. PrimeCraft checks every address against the borough's designation map before a price is committed.

Question 3

Do hip-to-gable loft conversions in Shepherd's Bush (W12) and Fulham (SW6) need planning permission?

Accepted Answer

On unlisted mid-terrace houses in W12 and SW6 that sit outside conservation area boundaries, a rear dormer within the permitted volume envelope usually qualifies under permitted development, requiring a lawful development certificate rather than a planning application. Building regulations approval is mandatory regardless — covering structural load, fire escape, and thermal performance. Hip-to-gable conversions are only available on semi-detached or end-of-terrace properties, not mid-terrace. Where the new structure runs to a shared wall, Party Wall Act notices must be served before any structural work begins. PrimeCraft submits the lawful development certificate, building regulations application, and party-wall notices as part of its standard service.
