Send your postcode, a short description of the works and any drawings or photographs you already have. We review the brief, identify any missing information and confirm a project-specific scope and fee.
We welcome enquiries across North, South, East, West and Central London, as well as surrounding areas. Site attendance, travel and availability are confirmed for each project before appointment.
Yes. We can provide structural input alongside your architect and builder. Share the latest plans and explain who is coordinating the project so responsibilities are clear.
It depends on the proposed works and the information available. Some design work can proceed from suitable drawings and verified measurements; other projects require site attendance or further investigations. We agree this at the outset.
Fees depend on the complexity of the project, the information available, the deliverables and any site attendance. We provide an individual quotation rather than a headline price that may exclude work your project needs.
We confirm current availability and an expected programme after reviewing your brief. The timing depends on the agreed scope and receipt of the information needed to complete it.
