This early 19th Century listed townhouse, located close to Belgrave Square, required significant structural and refurbishment works. The brief was to completely reconfigure the poorly executed and inappropriate 1960’s alterations, which were unsuitable for the building. A full basement structure was created under the entire building footprint. The new basement was a radical, but transformative solution and it allowed many advantages to enhance the flow and spaciousness of the final layout.

At the same time, there was a great emphasis placed on restoration of original features. The few remaining and salvageable architectural elements were rescued and reinstated. Effective replication of listed cornices and skirting’s were reinstated, creating a significantly enhanced building. The new design included a state-of-the-art temperature controlled wine cellar and additional wine storage under the main sub-structure. An Orangery / Conservatory extension was constructed at Ground Floor level to the rear, with a linking glass staircase and balustrade, allowing maximum light penetration to the Basement level.

With tenacity and perseverance, all of the objectives were achieved. The integration of a new comfort cooling system was particularly complex, due to the listed status of the building and the very stringent sound attenuation requirements, but this has worked flawlessly since its installation. A new mechanical and electrical system was installed throughout.

Following the extensive necessary negotiations with the Grosvenor Estate, IWA achieved a series of successful listed building consents and Planning consents from the City of Westminster.
