Mayfair · W1 · Layout, lighting and joinery, drawn before the price was fixed.Completed work, photograph

Layouts, materials, lighting and joinery, decided before the price is fixed, by one team.

Decided before the price is fixed, not on site.

Interior design settles layouts, materials, lighting and joinery before the price is fixed. We are NU Projects, design and build in Fulham SW6 since 2010. Our interior design fee is a flat percentage of the build cost. Call 020 7731 6841, and a budget estimate typically follows within seven days.

Our interior team works on layouts, materials, lighting, joinery, fabrics and finishes. Everything is drawn and scheduled, not left to site. Cost and programme are reviewed with the design, every week.

Design starts early, so it shapes the layout and the technical work. Kitchens, bathrooms, lighting and joinery often decide where services go. Those decisions are fixed long before decorative finishes go in.

Kitchens, joinery and furniture are made by Cochrane Bespoke, our joinery partner. Artwork is sourced through galleries and consultants. Our interior design fee is a flat percentage of the build cost.

What the work includes

  • Layouts, materials, lighting and finishes, drawn and scheduled
  • Kitchens, wardrobes, libraries and media units
  • Bespoke joinery and furniture by Cochrane Bespoke
  • Artwork sourced through galleries and consultants
  • Cost and programme reviewed with the design, every week
  • A flat percentage fee, agreed on the build cost

Kitchens and lighting decide where the services go. So the design starts early.

The design was intelligent and refined, the joinery was beautifully executed. Communication was clear throughout. The end result is a space that feels considered, elegant and timeless.

How a room is designed.

One guest bathroom in a Kensington townhouse, W8. Followed from the first plan to the last tap.

  1. 01

    The layout

    The room is planned first, to the centimetre. The shower and the WC each get a glazed cubicle of their own.

  2. 02

    The perspective

    Then it is drawn in three dimensions. You see the marble, the light and the joinery before anything is bought.

    The elevations

    Every wall is drawn flat, with its heights and finishes. Even the wall lights are named on the drawing.

When should interior design begin?

We start interior design early, so it shapes the layout and technical design.

Kitchens, bathrooms, lighting and joinery often decide where services go. We fix those decisions long before decorative finishes go in.

In our Chelsea terraced house, the media wall was built in, not bought in.

Who orders furniture, lighting and accessories?

Our appointment separates design and specification from purchasing, expediting, receiving and installation.

If you buy directly, we still need accurate dimensions and delivery dates.

Can I use my existing furniture or artwork?

Send us dimensions, photographs and any installation requirements early.

We then design around the items you want to keep. We consider circulation, proportions, lighting and storage.

What can be made as bespoke joinery?

Our joinery service makes made-to-measure furniture, cabinetry and doors, with matching materials and finishes.

We design every piece around the room, its storage needs and its use.

Each piece is priced from the drawings by our own quantity surveyor.
