Question 1

What does a rear-dormer loft conversion cost on an Edwardian semi in Surbiton or Tolworth (KT5, KT6, KT9)?

Accepted Answer

Spacious Edwardian semis along roads such as Maple Road in KT5 lend themselves naturally to rear dormers. Budgets for a double bedroom and en-suite conversion — covering steelwork, structural carpentry, dormer cladding, roofing, fit-out and Building Regulations fees — typically range from £50,000 to £76,000. Upgrading to a full hip-to-gable treatment adds roughly £10,000–£18,000 but brings a substantially larger usable floor area. PrimeCraft presents a line-by-line cost breakdown on the day of your site visit, so figures are confirmed before any design fee is committed.

Question 2

How do Kingston's planning rules affect permitted-development extensions in KT1, KT2 and KT3?

Accepted Answer

Most residential streets across KT1, KT2 and KT3 sit outside conservation area boundaries, so standard permitted development rights normally apply. Under the prior approval neighbour consultation scheme a single-storey rear extension can reach three metres on a semi-detached or terraced property — or six metres on a detached — without a full planning application. Certain riverside streets in KT1 and any locally listed buildings may carry additional restrictions. PrimeCraft confirms the exact planning position for each address during the free site visit, before the quote is issued, so there are no design-stage surprises later.

Question 3

Is it worth combining an extension, loft conversion and kitchen refit into a single contract in Kingston?

Accepted Answer

Running multiple scopes under one contract is how the majority of our larger Kingston commissions are structured. Structural groundworks for a rear extension in KT1 or KT2 can begin while detailed design for the kitchen and bathroom is still being developed, cutting the dead time between phases. Heating and boiler upgrades are folded in via our Gas Safe registered partner at the same time, avoiding a second mobilisation. A complete three-bedroom renovation programme across Kingston's KT postcodes typically spans 18–26 weeks; the same-day itemised quote covers every trade before work starts.
