The Office Group

Collins has completed the refurbishment and fit out of Chancery House on behalf of our client, The Office Group.

The Collins team and its partners, Opera, dMFK, Castle Hayes Pursey, Heyne Tillett Steel, Environmental Engineering Partnership and MLM, have delivered 165,000 sq. of works to transform an historic but worn building into a vibrant, sophisticated and high-quality, flexible working space.

The team carried out extensive structural works to extend the internal atrium from the ground to third floor, increasing the office floor area by 4,000 sq. ft, and creating a new roof and external curtain wall façade. The ground floor lightwells have been opened-up to create lower ground level courtyards and a new third floor roof terrace now offers outside space as part of the refurbishment.

The scheme, Collins’ largest to date, has exemplified complex structural works combined with high-quality fit out.

Challenges included:

Spatial constraints

• Installing large format tiling with careful consideration given to ensure tile joints were set out to suit partition arrangements.

• Floor to ceiling constraints on lower ground floor resulted in the team omitting raised access flooring where possible, re-specified finishes, re-coordinated high level services arrangements and formed various penetrations through structural components

Commissioning of mains ventilation systems

• The team developed a series of designed scaffold solutions to encapsulate ventilation intake locations to protect from general contamination. This allowed critical commissioning to progress alongside the completion of our landscaping works.

Drainage routes

• Management of lower ground floor drainage routes to allow connections to existing systems resulting in extensive investigations to ensure compliant falls could be achieved. This was further strained by the need to navigate varying floor void build-ups and the inability to introduce new connection chambers due to the close proximity over the London Silver Vaults.

With a state-of-the-art fitness studio, rooftop terrace and courtyards, natural light and high quality design detail, Chancery House proves that office space doesn't need to look like the office.​
