A Mayfair renovation is measured by more than the finish. The project must coordinate architecture, heritage, interior design, cost, building services, building management, specialist craftsmanship and discreet site delivery.

NU Projects provides an integrated route for private clients who want one senior team to carry the brief from early feasibility through construction, commissioning and aftercare.

Why Mayfair projects need a specialist strategy

Mayfair includes listed townhouses, mansion apartments, lateral conversions, penthouses and pied-à-terre properties. Many are within conservation areas or managed buildings. The project strategy may need to address heritage fabric, restricted deliveries, common-part protection, neighbour communication, service shutdowns, fire requirements and tightly controlled working hours.

Townhouse and apartment projects are different

Mayfair townhouses

Townhouses can combine period fabric with structural reconfiguration, new staircases, basement or roof work, climate control, lifts, security, kitchens, bathrooms and extensive joinery. These systems must be coordinated as one building rather than designed in isolation.

Mayfair apartments

Apartment renovations often require detailed coordination with a freeholder, managing agent or estate team. Licences to alter, access bookings, lift protection, acoustic requirements, working hours and service connections can shape the programme as much as the internal design.

What an integrated design and build service can include

Pre-purchase feasibility and existing-building review
Measured surveys, architecture and space planning
Planning, heritage and consultant coordination
Interior design, lighting, kitchens, bathrooms and joinery
Quantity surveying, cost planning and procurement
Mechanical, electrical, AV, controls and security coordination
Construction management, quality records and reporting
Commissioning, handover and structured aftercare

The appointment is tailored to the property. Explore NU’s architectural services and construction project management to see how the disciplines connect.

Cost planning without false certainty

A Mayfair budget cannot be derived reliably from a generic square-metre rate alone. Existing condition, approvals, access, structure, services, specification, joinery and procurement all influence cost. A useful cost plan exposes assumptions, allowances, exclusions and client decisions before the project reaches its most expensive stage.

MEP and interior design must develop together

Heating, cooling, ventilation, hot water, lighting, power, data, security and smart-home systems compete for space with ceilings, stone, bathrooms and joinery. Early MEP coordination protects the proportions and visual calm of the finished interior.
