17 Connaught Place, London

17 Connaught Place, London

Known formerly as Lex House, Designer Group undertook a full survey of the building and carried out the full Design and Build of the following services at this high quality office development covering 4,180sqm located at Marble Arch.

This development involved the complete renovation of the existing Connaught Place building in London. All the usable floor space was stripped out and extensively reworked, creating a  new modern flexible commercial space.

A new category A mechanical and electrical installation was completed by Designer Group on a design and build contract. The service shafts were completely stripped out and new mechanical services were installed. Electrically a new rising main busbar system was installed to feed new distribution boards at each floor allowing the client to lease the building to one or many tenants. Energy efficient solutions were used throughout the installation. All interior light fittings use LED lamps and are controlled by intelligent lighting sensors to allow daylight to supplement the light levels in the office space. The complete installation was designed, built and handed over within a 5 month period.

17 Connaught Place was completed March 2013.
