Corporate Offices & Workplaces
Office fit-outs, relocations and workplace transformation for corporate occupiers, managed on your behalf so the space works for your people and your budget.
Where we add most value.
CAT A and CAT B fit-outs
New leases, floor-by-floor fit-outs and refurbishments of occupied buildings.
Office relocations
From building evaluation and space planning to the move itself, with the business running throughout.
Workplace transformation
Reconfiguring space for hybrid working, collaboration and growth, informed by how the office is actually used.
Headquarters and boardrooms
Executive floors, boardrooms and client suites where the finish reflects the organisation.
Landlord and building approvals
Licences for alterations, building rules, services connections and building control.
Technology and furniture
Coordinating IT, AV and furniture suppliers into one programme.
What our clients need from their project.
- A realistic budget agreed before design starts
- Minimal disruption to staff and clients
- Landlord consent and building rules met first time
- One adviser accountable for programme, cost and quality
- Clear reporting for the board or overseas head office
Client-side, from brief to handover.
We act for you, not the contractor or designer: we set the brief and budget, appoint and coordinate the design team and contractors, and report to you at every stage. We do not act as your architect or interior designer unless appointed to do so; we make sure the right ones are appointed and deliver.
How client-side project management works- Brief: requirements, building evaluation, budget
- Design: coordinating the designers and specification
- Tender: competitive procurement and contract
- Site: programme, cost, quality and approvals
- Handover: commissioning, defects and move-in
