STRUCTURAL ENGINEERING ACROSS THE UK

Extension structural engineering

More room to live. A structure designed around the whole project.

The structure behind your plans

An extension needs to work with the existing house as well as stand in its own right. We review openings, foundations, floors and roof structure together to define a coordinated design scope.

What your scope can include

  • Rear, side, wraparound and double-storey extensions
  • Beams, columns, goalpost frames and large openings
  • Floor, roof and timber design
  • Foundation proposals based on available site information

What we need from you

  • Architectural plans, sections and elevations
  • Existing property drawings and photographs
  • Available ground information and nearby tree details
  • Party wall, drainage and previous alteration information
Foundation suitability depends on the ground, nearby structures and trees. Trial pits, ground investigation or specialist advice may be required before a final design can be issued.

From information to issued documents

Send your information through our quote form. We review the scope, confirm any missing details and provide a written quotation. Design and technical review follow once the appointment and required information are in place.

What you’ll receive

Your quotation identifies the calculations, drawings, report or responses to be issued. Documents set out the relevant assumptions and limitations so your project team can understand how to use them.

Common questions

Can you work from my architect’s drawings?

Yes. Send the latest drawings with their revision references. We will identify any additional measurements or investigations needed.

Do you cover every type of extension?

Rear, side, wraparound and double-storey projects can be reviewed. Feasibility, scope and the need for a visit are confirmed for each property.

How much will the work cost?

Fees depend on the structure, available information and required deliverables. You receive a project-specific written quotation before appointing the team.

How soon can you start?

Tell us your target dates. Availability and delivery timing are confirmed in your quotation; urgent or express work must be agreed before booking.
