New builds are springing up everywhere, with 204,500 brand-new houses built in the year leading up to March 2026. But our new homes are significantly smaller than those built during the Victorian (947 ft²), Edwardian (1,044 ft²) or post-war periods (883 ft²), coming in at around 818ft².

With more than 1.3m households stuck on a waiting list for social housing, it’s no surprise that developers are doing all they can to build new homes quickly. Unfortunately, fast often means smaller, with the average terraced home only 688ft². Apartments are even smaller, with only an average 656ft² of floor space.

The government has set specific limits preventing UK rooms from becoming too small. The minimum bedroom size for two people sharing in a home of multiple occupation (HMO) is 110ft², while the nationally described space standard sets the minimum floor area of a two-bedroom, two-storey home at 753.5ft², with at least 21.5ft² of storage.

Although it’s a step in the right direction to have a minimum storage space specified, for many families, this still doesn’t offer enough room. In this piece, sliding door wardrobe specialists at The Sliding Door Wardrobe Company have collaborated with Saddat Abid, CEO of Property Saviour, and Robin Edwards, Property Buying Agent at Curetons, to find out about some of the most creative uses of smaller spaces and box rooms that they’ve seen recently.

1. Dressing room

“The best conversions commit to one purpose completely,” Saddat explains. “A walk-in wardrobe, carved out of what was originally designated as a small third bedroom, quietly makes the main bedroom feel twice as calm because the clutter finally has somewhere to live.

“The main mistake people make with a small room is filling the floor and leaving the walls bare. In a small room, the floor is the one thing you cannot spare. Send your storage up with fitted cupboards or wardrobes, and hang a big mirror opposite the window – the room instantly feels lighter and twice the size.

“Pale walls with a single bold feature stop a small room from feeling like a cupboard. The moment a room stops trying to be everything and becomes on thing done well, it feels instantly bigger.”

2. Home office

“I’ve seen brilliant examples of small spaces converted into bespoke micro-offices with lots of built-in storage or dedicated ‘Zoom rooms’, complete with acoustic panelling,” Robin says.

“A proper home office is a fantastic way to utilise your box room,” Saddat comments. “Add a built-in desk that spans wall-to-wall, so you aren’t wasting floor space. Or, even better, choose one that folds flat against the wall once the day is done.”

Combine with a foldable office chair, wall-mounted cupboards for easy organisation and fitted bookcases to file away anything important and you have the perfect work-from-home office space. To really make the most of your small space, you could even add a larger monitor or wall-mounted TV to ensure a clear image when taking remote calls or working on a detailed project.

3. Library

“The best box room transformations give the room a clear purpose, rather than just trying to squeeze in an underused spare bed,” Robin explains.

“A small library with floor-to-ceiling shelves is the ideal way to style your box room, especially if you’re a book lover!” Saddat adds. Try adding fitted shelving to every single wall to fill the space with your book collection.

Add a small, comfortable chair, a foldable table for your cup of tea or coffee, plus a few strategically placed lamps, and you have your very own reading nook.

4. Home bar

“Another unusual but effective use for a box room is a compact home bar or wine storage area, often incorporating clever lighting and mirrors to increase the sense of space,” Robin suggests.

Install fitting shelving – the perfect place to store bottle of wine, Prosecco or Nosecco – and complete the look with a small bar area, decorative mirrors, low lighting and, of course, a mini fridge for the perfect chilled drinks.

Add a couple of bar stools or comfy chairs and invite your loved ones around for a delightful evening spent in your very own home bar. If you’re a dab hand at mixing drinks, you could even create your very own bespoke cocktails, complete with menu and tasting notes!

5. Hobby room

“A small room with a clear purpose adds real value and real happiness. A small room pretending to be a bedroom adds neither. A hobby room is a great way to tap into this idea,” Saddat explains. Why not create a space that revolves around your passion?

Love sewing and crafts? Create a room with enough space for your sewing machine, fabric collection and works-in-progress. Prefer painting? Design a space that houses all of your paints, paintbrushes, tools and canvases.

“Multi-functional spaces are a great way to create enough room to enjoy your hobbies,” Robin adds. “If you still need to include a desk or bed, try custom joinery or a Murphy bed system to help free up floor space.”

Crafting a space with the sole purpose of sparking your creative flair is not only fun, but also offers you a place of peace within which you can explore your own talents.

“What I would love is for people to stop apologising for these rooms and start designing them on purpose,” Saddat says. “New homes are smaller than they used to be, so the small room is not going away – it is becoming the norm.”

Robin agrees: “As modern new build homes get smaller, it’s more important than ever to use every single square foot of space to its maximum potential. Making these smaller rooms feel intentional, rather than just spare overflow storage space, is key.”
