An interior designer's effortlessly light and airy basement flat in London

In her basement flat in west London, interior designer Thea Speke has created a masterclass in lightening and brightening a potentially gloomy space

By nature of it being a basement flat, light was something that needed careful consideration – as were clever tricks to make the space feel a little lighter. Aside from the extension at the back with Crittall-style doors opening onto the garden and a rooflight overhead, the space is long, narrow and architecturally pared back, with a hallway running from the front to the back and doorways off it to bedrooms. ‘To prevent the entrance from being dingy, I added curtains to the front door, which make it really inviting,’ explains Thea. The entire hallway is fitted with three-quarter height tongue and groove, which, like the rest of the flat, is painted in a soft white. Wall lights – with a gently curved arm – lead you down the hallway, giving the feeling that you’re in a wonderfully cocooning space rather than a basement. Wisely for a small London flat, she also carved out space for a utility room – hidden behind a job door – as well as for coats, which are screened off by another floaty linen curtain.

Furniture and fabrics, Thea explains, were key to ‘softening and warming the space up a bit.’ She opted for curved shapes and pieces with a certain lightness, as a way to soften the clean lines of the architecture, especially in the extension. ‘Pieces such as these leather chairs were so useful, because you can see through them and they don’t look at all heavy in the space,’ says Thea, gesturing to a pair of vintage leather chairs. These sit alongside a sofa that was made bespoke to a design by her then-colleague, the designer Jessica Summer, and a pair of squishy Victorian armchairs.

In the sitting area, a sofa, made to a design by Thea’s friend and former colleague Jessica Summer, two reupholstered Victorian armchairs and two leather chairs cluster around a vintage table. The tall sculptural lamp cost £20 and Thea found it on Golborne Road. The little picture is deliberately hung low so that it can be easily seen while sitting.

For the kitchen, Thea had the units painted in a strong charcoal colour to tie in with the doors – a brave choice when she was on a mission for a light, airy feel, but one that paid off. ‘The cabinets are basically absorbed within the room and they draw your eye to the end of the room when you’re walking down the hallway,’ she explains. In the bedroom, Thea spruced up an old four poster bed that she inherited from her parents-in-law, painting its frame, adding a padded headboard and draping it in a lovely mix of ochre yellow linen and a ticking. ‘I wanted this bedroom to be grounding and restful,’ she explains.

Most of the pieces in the flat came from early morning market trips – squeezed in before work. ‘I’d fly there, leave with a bootfull of stuff, then fly home again and be at my desk by nine,’ she recalls. Ultimately, the sourcing missions not only helped Thea hone her eye, but also pushed her to leave Rose’s and set up on her own in 2020. Now she sells characterful European pieces through her online shop, as well as offering client-led interior design consultancy. ‘What I do varies hugely depending on the project,’ says Thea, who has recently worked with clients on houses in Suffolk, Gloucestershire and Marylebone. ‘It’s very much a conversation and a collaboration, rather than me imposing a scheme.’ As for the pieces she sells, it’s all about strong silhouettes and what Thea describes as ‘refined examples of their type’. A bit like this flat really.
