Renovating a property in London’s prime areas such as Mayfair, Knightsbridge, Belgravia and Chelsea is an investment that demands precision, expertise and an understanding of the market. In these neighbourhoods, expectations are high and only the best finishes, materials and craftsmanship will do. Understanding the costs involved ensures your project is both successful and delivers value.

NU Projects, The Real Cost of High-End Renovations in London’

Factors Driving Renovation Costs

High-end renovations in super prime locations are influenced by several key factors:

Property Type and Condition. A listed townhouse in Belgravia requires different expertise and permissions compared to a modern apartment in Knightsbridge.
Scope of Works. Full-scale refurbishments involving structural works, basement extensions and roof terraces will be at the higher end of the cost spectrum.
Level of Finish. Bespoke joinery, imported natural stone, high-end fixtures and custom lighting all add to the project cost but are essential for a luxury result.
Professional Fees . Architectural design, interior design, planning consultants and project management fees are critical investments to achieve the highest standards.

Average Costs by Project Type in Prime Areas

Full high-end renovation: £500 to £1,000 per sq ft
Basement construction with luxury finishes: £700 to £1,500 per sq ft
Kitchen and living space redesign: £150,000 to £400,000
Roof terrace and outdoor living: £100,000 to £250,000

These figures reflect projects in prime postcodes where quality and compliance are non-negotiable.

Why Costs Are Higher in Super Prime

Building in Mayfair or Chelsea means working within strict planning rules, often in heritage properties where only experienced contractors can deliver. Clients expect seamless finishes and premium materials, and tradespeople must be highly skilled. Additionally, the project must protect and enhance the value of the property, often worth tens of millions.
