A richly-decorated Regency house in Chelsea filled with an enviable array of antiques

The architect and designer Giles Vincent has reconfigured the rooms of his west London town house to set off a rich mix of inherited and collected antiques

The open-plan kitchen downstairs was also planned with the precision of a spacecraft. The grout lines of its tiles line up perfectly with the edge of the cupboards and the window, and even with the cream Aga. 'It might seem bonkers to go to all that trouble, but it makes the room seem comfortable because nothing jars.' The table in the adjacent dining room seats eight. 'I think it's important to have room upstairs to seat everyone you can fit around the dining table,' he says, explaining that this is why the sofas in the drawing room have a single base cushion - 'so, at a pinch, you can fit three people on a sofa if you need to'. Behind the dining table, he has made a slight projection on the wall to suggest a previous fireplace, then mirrored the walls on either side, hanging paintings on top of the glass at just the correct height so you cannot see the kitchen sink from the table or the stairs.

Giles takes a certain pride in the staircase he installed, as he points out the sinuous lines of the wavy, flat balustrade and explains how they were created. 'Each staircase tread needed banisters of two different heights, and numerous one-off designs were needed where the balustrade reduces in height, so we made full-size templates in cardboard to ensure that it would all work perfectly.' These are part of a theme of curves throughout the house, from the spritely Oliver Messel-inspired drawing room chimneypiece right up to the serpentine Thirties vanity in the main bathroom: 'I wanted a softer, more feminine look in the house.'

The staircase continues up, past a tiny and very pretty spare room on a half-landing. 'The width of the rear extension is one of the reasons I bought the house,' he says. 'It was just the right size to take a bed sideways on.' His own bedroom is at the top of the house and here he has borrowed space from the attic to create a vaulted ceiling. On every floor, meticulous planning ensures a spacious background, but it is his handsome antique furniture and his choice of fabrics that make this such a welcoming home.
