Upwards and outwards
By reconstructing a 21-storey building around its original core, we maximised the lettable space for this commercial office development squeezed into a site in the heart of the City of London.

Points of note
Maximising spaceTo enable two more of the upper podium floors to be let as office space, we relocated the mechanical and electrical plant from the seventh storey to the basement. As the plant requires greater height than the office floors, we fixed all the 27 new floors above them at different levels from the floors in the original building. Lettable space was also increased by leaning the building's frame outwards until the tenth storey, when it straightens to vertical.
Benefiting from our fit out expertiseThe Cat A fit out of the commercial offices was undertaken by our fit out specialists, Como. They were able to share logistics from hoists and cranes to the site’s clocking-in procedures on site. It also enabled us to overlap the final stages of construction work with the Cat A fit out, saving the client time and money.
Constrained logisticsSteel beams and columns used for the building’s construction were up to 12m long and had to be separately delivered and lifted into position one at a time. So that the drivers delivering the beams could safely navigate the narrow streets surrounding the site, we trained them on a practice track using a video representation of the road layout.
Being good neighboursTo minimise noise for the development’s neighbours, our team came up with an innovative solution and suspended acoustic screens around the site’s perimeter instead of using secondary glazing. This measure saved costs and reduced the number of noise complaints received.
“Undertaking such a major refurbishment in the heart of the City was a significant challenge, but the time taken to develop detailed logistics strategies with the City of London and other key stakeholders has enabled the project to be successfully delivered.”
“On a normal project of this size you wouldn’t get this sort of advance fit out activity happening while the shell and core contractors are still on site. It makes the transition so easy and smooth and it’s been great.”
