Applications go to RBKC & Westminster. We handle the Pre-App, planning submission, party wall awards, CIL calculations and conservation officer correspondence end-to-end.

Knightsbridge new build FAQ

What Knightsbridge self-builders ask us.

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

Typical 2026 Knightsbridge ranges (inc. design, planning, build, CIL & VAT): infill plots £576k–£1.5m; replacement dwellings £768k–£1.9m; garden plots £704k–£1.8m; large new builds £1.2m–£3.2m; multi-unit £1.5m–£5.8m+. The Knightsbridge multiplier (1.28×) reflects local labour, scaffolding logistics and finish expectations.

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

Always full planning permission via RBKC & Westminster. Multiple conservation areas overlap; Knightsbridge Green and Albert Gate are particularly restrictive. Listed buildings are common. Most Knightsbridge 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 Knightsbridge?

Mansion blocks, large stucco terraces, mews behind. Single-family homes are the exception, not the rule. Plot types that come up most often in SW1: 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 Knightsbridge are part of the equation — we help test feasibility before you commit to a purchase.

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

Allow 6–12 months for design and planning (longer in conservation-sensitive parts of Knightsbridge), 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 Knightsbridge?

Community Infrastructure Levy varies by London borough and zone, typically £20–£500 per m² of net additional floorspace. RBKC & 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.
