A smart townhouse on one of London's prettiest garden squares

The creation of a smart yet characterful setting for a collection of distinctive contemporary pieces in this London townhouse is especially impressive as it was achieved during lockdown by a Spanish design studio

Mindful of the owners' wish for this to be a working family home, Luisa decided to position the kitchen at the front of the house to maximise the light. A chic yet comfortable ochre-upholstered banquette, which follows the curve of the generous window bay, provides ample seating on one side of a pale marble-topped table, which is echoed by the marble surfaces on units designed and made by specialist Spanish furniture company Gunni & Trentino. Throughout the house, Luisa's team has used a thoughtful, restrained colour scheme of taupe, dark green, ochre and cream, which creates a feeling of cohesion and calm.

Adjacent to the kitchen is a supremely comfortable double drawing room, which is lined with a pale wool wall covering and furnished with armchairs and sofas in fabrics in this dark green, cream and taupe palette. These pick up on the colours of the large-scale contemporary paintings that are showcased on the surrounding walls. In the centre of the room, an intricately crafted chandelier by Cox London is suspended above an ebony table designed by Studio LO2.

Tall glazed doors open onto the hall, where a pinstripe effect on the walls was executed by Spanish craftsmen, who drew each line by hand while the plaster was still wet. At the far end, there is a discreet brass-doored lift; on the staircase, a zebra-striped carpet makes a bold statement.

Luisa's favourite space is the dining room: 'I'd always wanted to combine one with a library.' It is a handsome space with walnut joinery and panelling. Around the table are chairs by New York studio De La Vega Designs, which took over a year to be hand-crafted and shipped to the UK. They are, Luisa says, 'worth the wait'.

A bespoke oak-leaf chandelier by Cox London provides a dramatic centrepiece over a custom ebony table and benches in a geometric fabric from Pierre Frey. To the right of the marble fireplace is Anselm Reyle's Untitled, 2007, stripe painting.

Next door, in a more relaxed sitting room, striped red carpet runners have been used as an unusual wall covering, emphasising the comfort and luxury of this scheme. There is a sofa and chairs covered in dark grey velvet, which sit in contrast to two beautiful brass chairs.

Upstairs, the main bedroom has walls and curtains in an abstract fabric and an antique daybed beside the window. In the adjoining dressing room, black lacquer wardrobes with mirrored doors are the backdrop for an ethereal ceiling light by the Dutch artists Lonneke Gordijn and Ralph Naut, of Studio Drift. The en-suite bathroom, meanwhile, is a magnificently whimsical space, where Lefroy Brooks fittings are set off by a silk wall covering. The latter is by the Milanese specialist Misha and depicts a forested landscape.

The pièce de résistance? For some it might be found on the floor above, where the children's bedrooms have been designed with each child's interests in mind. One collects vinyl, so has album covers on the walls, while another has a special reading corner. These are playful, magical spaces. For others, it will be the jewel box of a screening room on the ground floor, its walls and seating upholstered in a dark green velvet from Güell Lamadrid. But for me, it is one floor below in the basement, where a beautiful spa area includes a quietly elegant swimming pool, a bar and a sauna in green marble. It is a brilliantly executed family home.
