How to combine two 1930s houses in style

Lizzie and Ion Florescu's idea to combine two adjoining Chelsea town houses has resulted in a unique home that maximises outside space and keeps work separate from day-to-day life.

The original Thirties buildings had two storeys at the front, with a single-storey section across the rear boundary and stepped flat roofs. The single storey at the back of both plots has been knocked through to form a long, elegant kitchen, which has a decked rooftop terrace garden above it. This outdoor space is shielded by the rear boundary wall of the rest of the property, trellised and planted with climbing roses and glossy, evergreen confederate jasmine.

Prior to acquiring the adjacent house, the Florescus had built a third floor onto the two-storey part of their home in 1993. The more recent conjoining project has created a matching floor on the other building, although this addition slightly differs in that it has a terrace section at the back looking down onto the garden terrace above the kitchen. It allows the sun to shine through to the courtyard when it is not directly overhead. It also provides third-floor outside space next to Lizzie's office.

The Florescus' conversion retained the position ofboth original staircases, and they have knocked through on the upper floors, which means there is a circular progression around the house. The dual staircases work particularly well as Lizzie and Ion's offices are situated on the second and third floors of the new side of the house, allowing business access to be separate from the domestic living areas. Situated on the upper floors of the original house, these include the main bedroom and the bedroom of the couple's son Leopold, bathrooms and Lizzie's dressing room. A basement under both houses was another part of the conversion, accessed by a new staircase on the 'office side' and also from a stairwell from the street.

Restraint and quality define the space. Teams of Italian craftsmen travelled to London to lay French oak flooring and to fit the marble for floors and bathrooms, perfectly cut to specification in Italy, then transported and slotted straight into place. 'The beauty of the materials and the installation were faultless and it still cost far less than from high-end suppliers in London,' says Lizzie. 'These wonderful Italians turned up in immaculate white overalls every morning from their B&B, breaking at 1pm for a proper cooked lunch at Carluccio's, then working on well into the evening to complete the job to schedule.'

The Florescus have a keen interest in design and objects, and they are responsible for much of the decor-ation and arrangement of the interiors. They both have international backgrounds and have lived in many different countries: the US, Canada, Saudi Arabia, Morocco, Switzerland, Italy and Romania. Wherever they go, they visit galleries, junk shops, antique shops and art fairs. Ion is of Romanian descent on his paternal side. He did not visit Romania until after the fall of the Berlin Wall, but since then has developed both business and philanthropic links with the country and has a particular interest in its artists and craftsmen. 'I like to mix Romanian pieces together with other Western art to put it in a world context. It stands up so well to comparison,' he says. This well-thought-through conversion certainly provides a fitting backdrop for the diverse collections of the couple's discerning eyes.
