A basement redesign not only adds to your living space (and therefore also adds to the value of your home), but we think it's a pretty good opportunity to realise that dream space you've always wanted but have never been able to quite justify – a cinema room, 'man cave', home gym, laundry room or maybe a stylish home bar complete with bespoke neon signand dance floor?

If you've got a big enough space, you could even install a modern kitchen and dining area downstairs – like the home owners achieved in one of the examples below. Short on space? A cool wine cellar with direct access from the kitchen should do it.

And to avoid the space being too dark and dull, create a big enough light well (hello courtyard garden) and install floor-to-ceiling glass doors and windows to flood the downstairs with natural light and turn it into a second ground floor.

Explore these 15 stylish basement ideas for all the inspiration you need...

Entertaining Space

Entertaining Space

Basement access is often from the front, so you usually have stairs under stairs. In order to help make the basement feel part of the house, these stairs are in the middle of the ground floor and sit on dainty legs with glass balustrades. This was crucial in order to bring in lots of light. Here the sunken area has become a cinema corner, complete with ceiling projector. As the basement is a big 60 sq m room, this is a great way to make an informal division of the space. The sunken area can be transformed into a dance floor and there’s even a bar. Get the look: Rug, Designer’s Guild.

Kitchen Diner

Kitchen Diner

This lower ground floor is a surprisingly light space, with iconic design shapes set against pale timber cladding and flush cabinetry, black-framed glazing and seamless terrazzo flooring. A pivoting door leads out into the garden and helps provide end-to-end natural light, while designer lights add illumination. Toys, games and the stuff of family life are stored in the run of handleless cabinets. Get the look: The table is a bespoke design by Clayton Cabinets. The Mobile chandelier and Tube wall light are by Michael Anastassiades. The dining chairs are vintage Mart Stam for Thonet. The concealed storage is by Tamzin Greenhill Designs, made by Grovecourt.

Proper Bar

Proper Bar

With a proper bar in the basement, there’s plenty to keep friends entertained over the weekend without ever getting bored.

Get the look: The bespoke bar, created by Made by Jason & Co, includes a brass bar top from The Copper And Zinc Bar Company.

Downstairs Kitchen

Downstairs Kitchen

This downstairs kitchen is made to feel light and airy through a large sky light, letting in light from the garden above. Despite the serious materials and design, there’s a whimsy to this space, thanks to the three-metre firefighter’s pole descending into the kitchen offering a shortcut way down.

Two Words: Wine Cellar

Two Words: Wine Cellar

Underground wine cellars by Spiral Cellars give you instant access to your wine collection via a top door and a – you guessed it – spiral staircase. Made from concrete and with an external diameter of 2.3 metres, they’re capable of holding up to 1900 bottles of wine. They can be installed under any ground floor room – great for kitchens but striking in a hallway too. Installation is short with little to no mess, you won’t need planning permission to have one installed, and the built-in ventilation system continuously replaces warm air with cool air. We’re sold.

Basement Den

These basement stairs are so much more than a route up and down when a graffiti artist’s stencil portraits of the kids perpetually climb the stairs.

Get the look: The graffiti mural is by Jason Busk. For a polished-concrete floor like this one, try Topcret.

Basement Hall

Basement Hall

When you build something from scratch, the danger is that it can feel a little too clinical. To give this basement character, the owners added touches of humour.
