Begin With the Bones, Not the Furniture

Mews houses are a peculiar breed. Most were built between 1800 and 1900 to serve the grand terraces behind them, which means they were designed around a carriage and a couple of horses rather than a family and a washing machine. The result is a footprint that is often just four to five metres wide, two or three storeys tall, hemmed in by party walls on both sides and lit only from the front and back. Before you sketch a single sofa, work out what is holding the building up. In many mews houses the first-floor joists span front to back, so the internal walls on the ground floor are doing very little. In others, a central spine wall carries the lot. A structural engineer's report is the cheapest money you will spend on the project, and knowing which walls can go will shape every decision that follows.

Open the Ground Floor, Then Put Something Back

Knocking through to create one long room is the obvious move, and usually the right one. But a completely undivided ground floor in a narrow house can feel like a tunnel, especially if the only light comes from the two ends. The trick is to keep the openness while giving the eye something to land on. A change in floor level, a ceiling that drops over the kitchen, a 900mm half-wall between the dining table and the sofa, or a structural column left exposed and painted — all of these divide space without blocking it. In the kitchen, a full island is rarely realistic in a four-metre-wide room; a slim peninsula run of 500–600mm deep, with seating on the outer side, gives you the same social layout without crowding the walkway.

Choose Doors and Screens That Disappear

In tight rooms, a door that swings is a door that steals a square metre. Pocket doors that slide into the wall cavity are transformative between a front reception room and a rear kitchen. Where you need separation but not privacy — a study, a snug, a playroom — slim-framed glazed screens keep the sight line running from the front window to the garden. Half-height partitions with a solid base and glazing above work well beside a staircase. If you must have a hinged door, consider a bi-fold or a door that opens flat against the wall. Every centimetre of clear floor you gain makes the whole plan feel more generous.

Treat Joinery as Architecture

Built-in furniture is the single most effective way to make a narrow house work. Rather than filling rooms with freestanding pieces that leave awkward gaps, commission joinery that runs wall to wall and floor to ceiling. Consider:

• Bench seating across a chimney breast, with drawers underneath for shoes, bags and board games.
• Window seats in bays or under front windows, doubling as storage and somewhere to sit with a coffee.
• Full-height wardrobes flanking a bed, so the room reads as a cabin rather than a box.
• Corner shelving that turns a dead angle into a library or a place for plants and pictures.

Paint the joinery the same colour as the walls and it recedes, making the room read as wider than it is. In a mews house, bespoke storage under the stairs and in every alcove turns wasted millimetres into genuine capacity.

Design the View From the Front Door

Stand at your front door and look straight ahead. Whatever is at the end of that line sets the tone for the whole house. Aim for a long view — through the ground floor to a rear window, a garden, or a well-placed mirror that bounces light back. Keep tall, bulky items such as a fridge or a wardrobe well off that axis, and put low furniture, rugs and lighting where the eye travels. This principle matters more in a mews house than almost anywhere else, because the plan is long and thin and there is nowhere to hide a mistake.

Let the Upper Floors Breathe Vertically

Upstairs, rooms are often smaller and ceilings lower. Resist the urge to cram. Keep the landing as a light well rather than a corridor, and use rooflights or a glazed stair screen to pull daylight down into the middle of the plan. Eaves and loft spaces, even shallow ones, can swallow suitcases, seasonal kit and the boiler. If you are adding an en-suite, position it over the kitchen rather than over a bedroom, and keep the shower away from the party wall to reduce noise transfer. Small, well-proportioned rooms that each do one job will always feel better than one cramped, multi-purpose space. The aim is not to fight the narrowness of a mews house, but to let its proportions do the work for you.
