Soho new build FAQ

What Soho self-builders ask us.

How much does it cost to build a new home in Soho in 2026?

Typical 2026 Soho ranges (inc. design, planning, build, CIL & VAT): infill plots £549k–£1.5m; replacement dwellings £732k–£1.8m; garden plots £671k–£1.7m; large new builds £1.1m–£3m; multi-unit £1.5m–£5.5m+. The Soho multiplier (1.22×) reflects local labour, scaffolding logistics and finish expectations.

What's the planning process for a new build in Soho?

Always full planning permission via City of Westminster. Soho Conservation Area covers virtually the whole neighbourhood. High listed-building density. Most Soho new builds start with a Pre-Application (£500–£2,500) to test feasibility, then a full planning submission running 13–18 weeks. Conservation areas, Article 4 directions and proximity to listed buildings add scrutiny.

What kind of plot makes sense in Soho?

Mixed-use Georgian terraces (upper-floor residential), small mews properties, and listed buildings. Plot types that come up most often in W1: replacement of an existing house (demolish + rebuild), side-garden infills on corner plots, and occasional backland sites accessed via a private drive. Plot acquisition prices in Soho are part of the equation — we help test feasibility before you commit to a purchase.

How long does a Soho new build take from purchase to keys?

Allow 6–12 months for design and planning (longer in conservation-sensitive parts of Soho), then 12–18 months on site for a single dwelling, 18–24 months for a large new build, and 24–36 months for multi-unit schemes. Our build programme is fixed in the contract.

How much is CIL in Soho?

Community Infrastructure Levy varies by London borough and zone, typically £20–£500 per m² of net additional floorspace. City of Westminster publishes its current CIL rates online; we calculate your specific liability at the planning-application stage. Section 106 affordable housing or infrastructure contributions may apply on larger schemes.
