Cumberland Mansions

by Base Interior

This was our fourth project for the same client, a private boutique developer, who appointed us to interior design and project coordinate the complete renovation of this 2,400 sq ft apartment in a large Marylebone mansion building.

The brief centred on the developer’s requirement for 4 bedrooms, all with en-suite bathrooms, as well as a large entertaining space and kitchen. The structure of the building was quite rigid and many walls had to be retained where fireplaces had once been sited. Initially The Portman Estate were not keen on the introduction of so many new bathrooms, however ultimately we managed to fulfil the brief, much to our client’s satisfaction.

A tight budget and an even tighter five-month timeline were set for us to complete the work. Upon appointment, our priority was to focus on the space planning and prepare documentation for all permissions from both the freeholder and head lessee, including the Licence to Alter and Building Notice; the fact that permission was granted for the new air conditioning system was a particular achievement. We created a comprehensive concept and detailed design specification to assist with this, as well as tendering the project, administering the contract, coordinating the build, and overseeing the procurement, installation and final handover.

The building’s period features were reinstated through the introduction of elegant cornicing, restoration of the sash windows and installation of solid parquet flooring. Classic furniture and lighting options, paired with more contemporary wall finishes and bespoke detailed joinery, resulted in a warm, inviting scheme.

In addition to air conditioning, the client required underfloor heating, a smart home system including Lutron, solid oak doors and an Italian kitchen complete with Siemens’ appliances, which were all incorporated in our scheme.

The project was successfully completed in September 2016.
