Chapter House

This full refurbishment of Chapter House, Old Street, transformed a dated building into a sleek, modern Cat A space with fully exposed services across five floors. Designed with flexibility in mind, the open-plan layout and industrial-style finish helped the building secure tenants quickly after completion. The project involved complex coordination, new incoming services, and structural alterations, all delivered under tight programme constraints and BREEAM requirements. Through detailed 3D design and careful visual planning, we achieved a clean, functional aesthetic that meets both current market expectations and future tenant needs.

This cut-and-carve Cat A project involved a full building refurbishment with fully exposed services, from basement to fourth floor, encompassing the reception and communal areas. The intent was for open plan arrangement offices, ready for incoming tenants to sub-divide, and so our design had to allow for the easy flexing of service capacity to suit future fit-outs.

The former Hertford House was in a tired state, desperately in need of a refresh to bring it up to the modern expectations of any incoming tenants whilst maximising ROI for the landlord.

Integra was chosen to carry out the M&E works due to the complex exposed services design coordination. There were a lot of areas that could have become pitfalls if consideration wasn’t given to avoid these – we worked with BREEAM design requirements and tight programme sequencing alongside structural works. All incoming services were completely new, and an additional floor and side extension were constructed as part of this project.
