Structural Engineer for New Builds – Safe, efficient new build structural design
As your structural engineer for new builds, we design the foundations, frame and roof so your architect and builder have everything they need.
- New build foundations, floors, steelwork and roofs designed as a complete system.
- Fixed-fee structural calculation packs, agreed in writing before any design work starts.
- Chartered-level oversight on all new build designs for peace of mind.
We work with homeowners, developers and architects across the UK, providing new build structural designs that satisfy Building Control and keep your project moving on site.
What we design for your new build home
We cover every structural element your architect and builder need for a safe, efficient new house build.
Steel beams and frames
- RSJ beams for wide openings, feature spaces and double-height areas.
- Goalpost and portal frames where stability or large glazing is needed.
Timber floors and roofs
- Joist layouts and trimmers sized for modern finishes such as tiles or concrete screeds.
- Trussed or cut roofs, including hips, valleys and feature ceilings.
Loadbearing walls and columns
- Masonry and steel columns checked for vertical loads and stability.
- Padstones and bearing details clearly noted for your builder.
Lateral stability and wind
- Shear walls and wind bracing designed so the building can safely resist horizontal loads.
- Roof diaphragms and straps set out for Building Control and your builder.
Retaining walls and level changes
- Garden retaining walls and semi-basement walls checked for ground and surcharge pressures.
- Drainage and waterproofing notes where needed.
Information we need to design your new build
Good information in means a smoother design process, fewer queries on site and quicker Building Control sign-off.
Architect drawings in PDF or DWG
- Plans, elevations and sections showing the proposed layout, roof form and levels.
- We are happy to work directly from architect PDFs or DWG exports if your designer prefers.
Site investigation or soil details
- Any trial pit logs, existing foundation information or ground reports if available.
- If you do not have a report yet, we can advise what your engineer or geotechnical consultant should cover.
Basic loading and finishes
- Wall types, floor make-ups and any heavy finishes such as stone, large tiles or balconies.
- Any special items such as roof lanterns, plant or solar arrays.
Project address and timings
- Site location, planning status and whether you already have Building Control appointed.
- When you hope to start foundations and frame so we can agree realistic timeframes.
