Cowley House Material sourcing and procurement, design co-ordination, cutting sheets, on site quality control and project management

Built in 1905, Cowley House was designed in the style of Baroque 17th Century and is set within one of the best preserved Georgian streets in London. A Grade II listed building, it is a few minutes’ walk from the Houses of Parliament, and for over 30 years it was the headquarters of the Liberal Democrat Party.

This development converts the office space into a luxurious, super-prime residence complete with seven bedrooms, six bathrooms, gymnasium and indoor heated pool.

With a market value in excess of £20 million, only the highest quality materials were specified. To enhance the opulent interior, marble and natural stone were used extensively throughout the property.  This included bookmatched Calacatta flooring in the hallways from the basement to the second floor, bookmatched bathrooms in Bianco Fantastico and swimming pool floors and wall cladding in Moleanos limestone.

Stone & Ceramic won the stonework contract, but with limited resources for this type of project, they employed The Stone Consultants to manage the entire stonework package.

The Stone Consultants set about the procurement of six different types of stone and marble. Surveying and producing
drawings and cutting sheets, they visited suppliers in Italy to select the materials and confirm that the quality and capacity of the suppliers would meet the requirements of the project. With the client demanding the very highest standards and a tight installation programme, the process of factory visits continued throughout the contract to ensure the required quality and supply were maintained.

With the stone procurement on track, The Stone Consultants turned their attention to the stonework contract on site. The installation programme was key to the success of the project for the main contractor. Dealing with design changes and minimising their effect on delivery was a critical element of the project management, together with implementing a strict quality control procedure for the installation.

The Stone Consultants needed meticulous attention to detail to ensure the client’s high standards were met throughout the contract, but particularly with the bookmatched marble, which is notoriously complicated to procure and install correctly.

“The Stone Consultants’ service was excellent. From trips to Italy to select the material and drawing approval of complicated book-matched materials to production and site QA, the stonework was a great success. The project has now been nominated for a Natural Stone Award.”
