01Commercial
Start with the use. Then the building.
A commercial project starts with the use: who occupies the building, how people move through it and what the proposed change needs to achieve.
Looking for a commercial architect usually means a decision about a building or site is waiting on information. We help you develop the proposal and identify the design, planning and technical information it needs to move forward.
Architectural design, planning applications, Building Regulations drawings and structural engineering are coordinated within the practice, so each stage describes the same proposal.
- The building or site
- Its current use, layout and construction, and any drawings or planning history you hold.
- The proposed use
- Who will occupy the space, how it will operate and what needs to change.
- Approvals and information
- Whether planning permission, Building Regulations approval or structural design is likely to be needed.
- The decision ahead
- The design, appraisal or application information needed for the next step.

Feasibility
03The process
From feasibility to technical delivery.
- F
Feasibility
Where useful, an early review of what a building or site could accommodate and the planning options.
- D
Design
Layouts and proposals developed around the use, access and circulation the building needs.
- P
Planning
The planning route confirmed, and an application prepared where permission is required.
- T
Technical
Building Regulations drawings, coordinated with structural design and calculations where required.
04Planning / Building Regulations
Two approvals. Prepared together.
Planning
- Considers
- The proposed development or use, and its effect on the site and surroundings.
- We prepare
- Planning drawings and supporting information, and manage the application.
- Decided by
- The local planning authority.
- Commercial focus
- Change of use, alterations to premises and development proposals.
Building Regulations
- Considers
- How the building work meets the technical requirements for its use and occupancy.
- We prepare
- Technical drawings and Full Plans information, coordinated with structural input.
- Decided by
- A building control body.
- Commercial focus
- Alterations, change of use works and new structure.

05Structural engineering
Structure for commercial buildings.
Commercial work can involve larger spans, new openings in existing buildings or entirely new structure. Structural design is carried out within the practice, from alterations to framed and multi-storey buildings, supported by computer structural analysis.
Considering the structure while the layout develops means openings, spans and the layout can be coordinated before the technical information is finalised.
Structural design covers
- Reinforced concrete
- Steel frame
- Composite construction
- Masonry
- Timber
