Chelsea’s townhouses, terraces and mansion-block apartments offer character, but many were designed for a very different way of living. A successful renovation must improve light, circulation, storage and comfort without stripping away the proportions and details that give the property its value.
NU Projects delivers Chelsea home renovations through one team covering architecture, interior design, cost planning, building services and construction.
Start with the whole home, not the kitchen alone
A new kitchen often exposes wider questions. Should the ground floor be opened up? Can the staircase, utility space or guest WC work harder? Where will plant, ventilation and storage go? Considering the complete layout first prevents an expensive room from being designed around unresolved circulation and services.
Working with a Chelsea period property
Retain the right character
Cornices, fireplaces, staircases, doors, floor patterns and room proportions should be assessed before strip-out. The design can then decide what to restore, replicate or reinterpret rather than treating every original element as an obstacle.
Plan structure and services together
Large openings, rooflights and level thresholds affect steelwork, drainage and waterproofing. At the same time, underfloor heating, cooling, ventilation, lighting and controls need coordinated routes. This work should be resolved in the technical package before the decorative finishes are finalised.
Understand the approvals
Planning, listed-building status, conservation constraints, freeholder consent and party-wall matters depend on the property. A flat may require landlord approvals even where external planning is not triggered. The correct route must be established for the individual address.
Creating a high-end kitchen and living space
- Place everyday storage and utility functions before styling
- Use sightlines and lighting to connect kitchen, dining and garden
- Coordinate extract, cooling and underfloor heating with the ceiling and joinery
- Select durable natural materials with repair and replacement in mind
- Define appliance, stone and bespoke-joinery lead times early
- Mock up important junctions, handles, lighting details and finishes
Budget and programme control
The cost plan should separate structural work, building services, kitchen, joinery, finishes, professional fees, statutory costs, contingency and VAT. A realistic programme must include surveys, design, approvals, procurement and commissioning as well as site time.

Why real project evidence matters
A contractor should be able to explain what was designed, what was built and how quality was controlled. Review the NU Projects portfolio for completed residential projects and the level of finish achieved.

Frequently asked questions
Do Chelsea renovations always require planning permission?
No. It depends on the work, property type, heritage status and local restrictions. External alterations and extensions are more likely to require consent than internal refurbishment, but every address should be checked.
Can NU manage design and construction?
Yes. NU can coordinate architecture, interiors, consultants, cost planning, procurement, construction and aftercare through one accountable team.
Can clients remain in the property?
That depends on scope and safety. For extensive structural, services and whole-home work, moving out is usually more efficient and less disruptive.
