Interior design · London

Interiors designed with the house, not after it.

Kitchens, bathrooms, joinery, lighting and finishes, designed by the same team as the architecture, so every room is resolved from the structure to the door handles.

Arrange a free visit What we design

Most interiors are fitted into a finished shell. Ours begin at the first sketch, because the position of a beam, the height of a ceiling and the place for a kitchen island are architectural and interior decisions at once.

What we design

Every part of the inside of the house, drawn and specified so it can be priced and built as intended.

  1. 01

    Layouts

    How rooms connect, where furniture sits, and how daylight moves through the plan at different times of day.

  2. 02

    Kitchens

    Layout, islands, storage and appliances, drawn to be priced by a kitchen maker and coordinated with drainage, extraction and power.

  3. 03

    Bathrooms

    Bathrooms, en-suites and cloakrooms, with sanitaryware, tiling, lighting and ventilation specified together.

  4. 04

    Joinery

    Wardrobes, shelving, media walls, window seats and staircases, drawn in detail for a joiner to make.

  5. 05

    Lighting

    Lighting layouts for daily use as well as atmosphere, coordinated with ceilings, joinery and switching.

  6. 06

    Finishes and furniture

    Floors, stone, tiles, paint and ironmongery shown as physical samples, with furniture and fittings scheduled against a budget.

Open-plan kitchen and dining room with herringbone oak floor, white island and sliding doors to the garden

Designed with the extension

18 Downsway, South Croydon

The kitchen, dining table and garden doors were planned as one room from the start. The island faces the garden, the rooflight sits over the worktop, and the dining table takes the light from the full-width glazing.

See it before you choose it

Every key room in 3D, before anything is ordered

We model the kitchen, living spaces and bathrooms in three dimensions with the materials you are considering, so you can compare a stone, a timber or a lighting scheme on screen rather than on site.

Physical samples of every finish follow, so the decision is made in daylight, in your house.

Three ways to work with us

Each stage has a fixed fee, agreed before it starts.

  • Most clients

    With your building project

    Interiors designed alongside an extension, basement, loft or new house, starting at concept stage so kitchens, lighting and joinery shape the architecture rather than being fitted in later.

  • No building work

    Interiors only

    For a house you have just bought or want to refresh: layouts, kitchens, bathrooms, joinery, lighting and finishes, without structural work.

  • Developers

    New homes and show units

    Specifications, kitchens, bathrooms and finishes for new apartments and houses, pitched to the market and the budget, with show-home styling.

How the process runs

Interior design is best started at concept stage, while kitchens, lighting and joinery can still shape the walls, windows and services.

  1. 01

    Brief

    How you live, what you own and want to keep, your taste and your budget.

  2. 02

    Concept

    Layouts, a material palette and reference images, for you to react to.

  3. 03

    Developed design

    3D views, kitchen and bathroom designs, joinery and lighting layouts.

  4. 04

    Specification

    Finishes and furniture schedules with suppliers and costs, ready for pricing.

  5. 05

    Delivery

    Site visits during installation, coordination with trades, and styling at handover.

Common questions

When should the interior design start?

During concept design. Kitchen layout, lighting and built-in joinery affect window positions, structure and services, so they are far cheaper to settle before the building regulations drawings are finished than to retrofit later.

Why have the same practice design the architecture and the interiors?

Because the decisions overlap. Ceiling heights, the position of a beam, a joinery recess or a lighting track are architectural and interior decisions at once. Designing them together avoids the compromises that appear when interiors are fitted into a finished shell.

What does an FF&E schedule cover, and how does it help with budget?

Fixtures, furniture and equipment: the loose and fitted items that finish a space, such as furniture, lighting, sanitaryware and soft furnishings. The schedule lists each item with its supplier, finish and cost, so decisions are made against a budget rather than item by item.

Can you work on interiors only, without building work?

Yes, though most of our interior work is part of an extension, renovation or new build we are designing.

Free first visit

Let's look at the rooms together

A director will visit, see how you use the house today and talk through what the interiors could become, what it might involve and how we would phase it. There is no charge and no obligation.
