Capital were appointed by The Royal Borough of Kensington & Chelsea (RBKC) to provide design services from RIBA Stage 2 for the re-cladding and associated works at Adair and Hazelwood Towers.
Contract Value:
Circa £7m
April 2019 – February 2023
JCT Design & Build Contract
Capital were appointed as Lead Designer, Architects, Employers Agents, Project Managers, Structural Engineers and Cost Consultants. We were responsible for undertaking a peer review of works carried out prior to appointment and developing a more holistic approach. During our initial investigations, we found further A1 solutions available and were able to propose these within our options appraisal.

The brief was  to reclad the towers utilising an A1, non-combustible system and to develop a bespoke procurement solution meet strict governance procedures. Given the sensitive location of the blocks, there was an increased requirement for resident liaison coordination and consultation.

Capital presented our proposal to RBKCs Planning and Building Control departments for early buy in and hosted numerous resident engagement surgeries. At these surgeries we provided samples of key components and architectural renders of alternative cladding options.

Key to the delivery of the project was the procurement route, which was to meet the requirements of leasehold services, OJEU and the overall programme. Capital developed a bespoke  procurement  route under a two stage design and build process where the contractor was to be fully engaged from the start and worked closely with the design team to develop and agree the most appropriate and cost effective design solution.

We were also responsible for developing and formulating the employer’s requirements and contract documents, coordinating the design team, Contract Administration and agreeing sign off and handover procedures on site.  Recently the Project obtained planning permission following a sympathetic design undertaken by Capital.

These works mark the first Cladding schemes undertaken by RBKC since the Grenfell Tragedy.
