An Edwardian townhouse in London gets an infusion of colour and joy from Kate Guinness

With a bright new extension by David Hingamp of Archic, this classic London house was perfect for the owners' growing family, but it needed the confident hand of interior designer Kate Guinness to make the decoration sing

Kate was brought on board after construction had started, when the owners began to feel nervous about the decorating aspect of the project, in particular, managing the transition from the Edwardian part of the house to the modern extension.

‘I made one visit to Chelsea Harbour Design Centre and felt completely overwhelmed,’ recalls the owner. ‘We only had three pieces of nice furniture, and the two orange ‘Husk’ sofas by Patricia Urquiola, which I had bought in a moment of madness and we had this big house to fill.’ Without help, she worried the process would be long and frustrating, but also that she would fall back on boring, but safe choices.

‘One of the things I love about what David Hingamp did is the tree-filled courtyard-cum-lightwell and the grass and wildflowers roof of the sloped side return. It means when you stand in the reception room there is greenery as far as the eye can see,’ says the owner.

An Instagram ‘rabbit hole,’ led her to Kate’s website. ‘I looked at her projects and thought: “Yes. That’s what I want.” What I love about her houses is they are beautifully designed but don’t look designed. They look like they’ve been lived in for years,’ she enthuses. Although the owner and her husband wanted the house to have lots of colour and pattern, and to include mid-century design, they were otherwise happy to surrender Kate’s expertise. ‘I knew that Kate understood our taste, but I was also excited for her to challenge and teach us.’

They did however have a list of practical requests, among them a dining table large enough to seat 10, bedrooms for the twins that had their own identities but were connected, and study. ‘After years working on the kitchen table surrounded by the kids and their toys, I longed for a room of my own in a style that contradicts the challenges of my work,’ says the owner. In response, Kate has designed a fresh and uplifting workspace around a wallpaper by Josef Frank. ‘It genuinely has a positive psychological effect. My colleagues call it their favourite zoom box,’ says the owner.

In the reception room Kate celebrates the owners’ love of mid-century design with a decorative Swedish cabinet circa 1940s from 1stdibs.com and the ‘Utrecht,’ armchair, which was designed by Gerrit Rietvield in 1935 from Cassina.

The brass ceiling light from The Kairos Collective with walls in ‘Clove 60%’ by Edward Bulmer are the perfect foil for a large-scale watercolour painting by Swiss artist Uwe Wittwer.

On the top floor, Kate made additional structural changes, including incorporating part of the landing into the bathroom to create a larger shower. ‘It’s a dark room so we embraced that by choosing rich colours and running the tiles up the pitched ceiling to make it feel dramatic and interesting,’ explains Kate. She also flattened the wall with the chimney breast so the bed could sit more centrally and replaced built-in joinery with free-standing pieces. The owner wanted this space to feel like checking in at a Soho House hotel, so Kate has added a decadent free-standing rolltop bath under the window.

As the owner anticipated, Kate has managed the transition from traditional to modern with aplomb, deftly softening the modern extension with interesting textures, including a wool wall hanging by Els Jennings and sculptural ‘Anders’ pendant light from Pinch, while updating the older part of the house with modern and mid-century pieces, such as the Matthew Cox table and vintage brass pendant light in the reception room. The house is further unified by a meticulously chosen paint scheme that is both sophisticated and serene.

To Kate’s delight, the owners have since added a contemporary art collection to the house, which they assembled with the help of their friend, curator and art advisor Louisa Adam. But no one is more delighted than the owner. ‘The house makes me happy every day. It’s an extraordinary privilege and I still pinch myself.’
