Bay windows and deep window recesses are common in period London homes, and most of the time they’re left as dead space, maybe with a radiator underneath and not much else happening. A fitted window seat with built in storage turns that gap into one of the most useful corners in the room, without taking up any floor space you’d otherwise use for furniture. It’s a small addition that solves two problems in one go: somewhere to sit, and somewhere to put things.
Why This Works So Well in Period Homes
Older London properties often have window recesses that are just deep enough for a proper seat, something newer builds rarely offer. Rather than letting that depth go to waste, a fitted seat uses it fully, built to the exact width and depth of the recess so it looks like it was part of the original house rather than an addition. Because it’s fitted rather than bought, it can also be shaped around radiators, skirting boards, and uneven wall lines that a freestanding bench simply couldn’t work around.
Where a Window Seat Makes the Most Sense
Bedrooms. A window seat with storage underneath is one of the easiest ways to add extra clothing or linen storage to a bedroom without needing another wardrobe. It also creates a quiet spot to sit that isn’t the bed, which is worth more than it sounds in a small room.
Living rooms and bay windows. In a room with a bay window, a fitted seat running the width of the bay makes use of a space that’s often just floor with a curtain over it. Add cushions and it becomes genuine seating, not just storage with a lid.
Children’s rooms. Storage is always at a premium in a child’s bedroom, and a window seat gives a place to stash toys, books, or bedding while doubling as a reading nook, something that tends to get used more than people expect.
Home offices. In a smaller home office, a window seat can double as an informal second seat for calls or reading, while the storage underneath holds files, stationery, or anything you don’t need reaching for daily.
Storage Options Underneath
The seat itself is really just the visible part. What’s underneath is where the real usefulness comes in, and there are a few ways to design it.
A lift up lid with hinges gives you one large storage cavity, good for bulkier items like spare bedding or seasonal clothing, though everything inside is stacked together rather than separated. Drawers built into the base are better suited to items you need more regular access to, since you’re not lifting the whole seat cushion to get at them. Some designs combine both, a smaller drawer section at one end with a lift up section for the rest, which tends to be the most practical layout for day to day use.
Getting the Comfort Right, Not Just the Storage
It’s easy to focus entirely on the storage and forget that people will actually sit here. A seat height around standard dining chair height, roughly 45 centimetres, tends to feel most natural. Depth matters too, a seat under about 40 centimetres deep can feel more like a ledge than somewhere to sit comfortably. A cushioned top, either a loose cushion or a fitted upholstered pad, makes a real difference to how much the seat actually gets used rather than just admired.
Matching the Rest of the Room
Because it’s built in, a window seat can be finished to match existing skirting boards, panelling, or other fitted furniture in the room, which is part of what makes it feel like it belongs rather than looking like an afterthought. A painted finish that matches the woodwork, or a fabric that ties into the room’s existing colours, keeps the whole thing feeling considered rather than bolted on.
Getting the Design Right
Every window recess is a slightly different shape and depth, so getting an accurate fit means having the space measured properly rather than guessed from a tape measure. A designer visit covers the measurements, the storage layout that suits how you’ll actually use it, and the finish that fits the rest of the room.
