Structural engineering services for homeowners

We provide practical structural design for wall removals, extensions and loft conversions – focused entirely on residential homes.

This page explains the main types of projects we routinely design and the kind of service you can expect.


Core services

Knock-throughs and wall removals

Structural design for removing load-bearing walls, for example opening up between a kitchen and dining room or creating larger living spaces.

  • Beam sizing and support details
  • Calculations for Building Control
  • Clear, practical drawings for your builder

Typical fee for a straightforward knock-through is around £450 fixed price, no VAT, including site visit and full structural design.

Single-storey rear extensions

Structural design for rear extensions, including openings into the existing house, roof structure and supporting beams or lintels.

  • Works with your architect’s drawings
  • Designs coordinated with Building Control requirements
  • Focus on buildability and cost-effective solutions

Two-storey extensions

Full structural design for larger extensions adding both ground and first-floor space.

  • Load paths and supports through to foundations
  • Stability considerations and bracing
  • Details suitable for Building Control submission

Loft conversions

Structural design for loft conversions, including floor strengthening, new beams, dormer openings and roof alterations.

  • Practical solutions that work with existing structure
  • Details for steelwork and timber members
  • Calcs and drawings ready for Building Control

Other residential projects

In addition to the above, we routinely design:

  • Sunrooms and orangeries
  • New-build houses
  • Major internal alterations

If you’re unsure whether your project fits into one of these categories, you’re welcome to call or email to ask.

What we don’t do

To keep our focus on homeowners altering their properties, we do not normally provide:

  • Commercial structural engineering work
  • Structural reports for property buyers or sellers

Our work is centred entirely on structural design for home alterations and extensions.


How we work with you and your architect

Most projects start with your ideas and, where available, your architect’s drawings. We then:

  • Discuss the proposed layout and any structural options
  • Carry out a site visit to understand the existing structure
  • Develop a practical, buildable design that meets Building Regulations
  • Provide drawings and calculations for your builder and Building Control

Throughout, the emphasis is on clear communication, practical details and avoiding unnecessary construction cost.
