What your structural package includes
A typical structural engineering package includes:
- Structural calculations for beams, joists, rafters, and supports
- Steel beam (RSJ) design
- Padstone and bearing details
- Foundation design and load assessments
- Structural layout drawings
- Connection details
- Wind load and point load analysis
- Coordination with architectural and Revit drawings
- Building Regulations‑ready documentation
All calculations are produced to UK standards and accepted by Building Control.
Our process
A coordinated, accuracy‑driven workflow:
- Review of architectural drawings We assess your plans, load paths, and structural implications.
- Site survey (if required) We inspect existing structure, materials, and constraints.
- Structural design Beams, frames, foundations, and supports are engineered to specification.
- Calculations & drawings We produce Building Regulations‑ready documents and structural layouts.
- Building Control submission We prepare documents for approval and respond to any queries.
Fees
Typical fees start from:
- £295–£495 for single beams or wall removals
- £495–£895 for loft conversions
- £695–£1,495 for extensions
- £1,495+ for new builds or complex structures
A fixed quote is provided after reviewing your drawings.
Borough‑specific considerations
Structural requirements vary depending on local policy, building age, and construction type. We specialise in:
- Kensington & Chelsea — older buildings, heritage structures, complex load paths
- Westminster — façade retention, basement structures, conservation constraints
- Camden — terraced properties, party wall implications, roof alterations
- Lancashire authorities — traditional masonry, foundation upgrades, extensions
- Conservation areas — structural solutions that preserve original fabric
Your structural design is tailored to your building type and borough requirements.
Common mistakes to avoid
Projects often face delays or Building Control rejections when:
- Builders remove walls without calculations
- Beams are undersized or incorrectly supported
- Architectural drawings and structural drawings don’t match
- Load paths are misjudged
- Foundations are not designed for soil conditions
- No structural engineer is involved in loft conversions
Planning World eliminates these risks with fully engineered, compliant solutions.
