Technical design

01What the package holds

Stage 4 turns the planning drawings into the information a scheme is built from. We produce fully coordinated architectural technical design: site and substructure plans, GA plans, sections and elevations, the roof plan and MEP plans. Wall types and the fire plan sit alongside build-up details, cladding, fire stopping and the interface details at the ground floor, external walls, roof and internal junctions. Window and door details and schedules, stairs, kitchen and bathroom layouts, and bin, bike and laundry stores complete it, with Building Control notes and specifications.

02Resolved before it is bought

Ducting, plant and utility cupboards are worked out in the 3D model, so they do not clash on site. We run regular design team meetings, keep a planning condition tracker, make the condition submittals and track Building Control conditions where the job needs it. Once the scheme is on site we attend monthly progress meetings and stay in touch with the planning officer.

03Where engineering and manufacture take over

Fire, structural and MEP engineering are by others, as are SAP and Part L calculations, overheating analysis, the NBS specification and the Employer's Requirements. Manufacturing and shop drawings are not part of Stage 4. When a factory is building the scheme, that work moves to our DfMA manufacturing drawings service.
