Structural engineers for family homes

Your house probably needs less steel than you’re about to pay for.

We design the structure lean, and we design it early, so the build costs less. Walls out, extensions, lofts and cracks, for families getting their house done.

We reply within one working day.

The steel beam sits in a boxed-in bulkhead above the opening. The lime line follows the weight from the roof, along the beam, down each pier and into the ground.

  • We reply within one working day.
  • Fixed fee, confirmed in writing before we start.
  • We answer Building Control’s questions on our calculations as part of the job.
  • We are insured.

We work from your drawings and photos anywhere in England, with a site visit where the job needs one.

The idea

Every beam is paid for by the kilo.

A bigger beam is quicker to design, and nobody complains about one. You pay for the difference.

One published case: 700 kg of steel saved on a £50,000 rear extension.

Same safety, same codes, less waste. The earlier we are involved, the more of your structure is still worth optimising.

Two sections at the same scale. Both designs meet the Building Regulations; one carries steel the house never needed.
Key to the drawings
  • Existing masonry A flat tone: everything already there, cut or seen.
  • Concrete Aggregate triangles and fine dots, scattered at random: foundations, slabs, padstones, lean-mix cavity fill, encasement.
  • Undisturbed ground Basket weave, as a band that follows the ground line and fades out.
  • Hardcore Large open zigzag, the depth of its own layer.
  • Timber, cut A box with a cross. Seen along its length, an outline only.
  • Steel, cut Solid, at the section's true proportion.
  • DPC Heavy dashed line, as Approved Document C draws it.
  • Load path Where the load goes, from the roof to the ground; dashed where it runs beyond the cut.
  • Load marks Arrows at the symbol weight: loads down onto a member, bearing up under a foundation.
  • Hidden, beyond or removed Out of the cut, beyond it, or taken out.
  • By others, beyond Faint: frames, coverings. Not our structure.
  • Cloud Confirm on site. Never a revision mark.

What are you thinking of doing?

Pick one and watch the model draw it.

What each one involves

Timing

Options close as the project advances.

Each decision, once made, stops being one we can improve for you.

  1. Just an idea

  2. Talking to an architect

  3. Drawings are being done

  4. Planning application in

  5. Planning granted

  6. Out to builders for prices

  7. On site

Under each stage, five levers: layout, openings, structural approach, foundations and member sizes. Tall is open, short is closing, a hairline with a lock is fixed.

Watch it close, stage by stage

How it works

Four steps, and no surprises in the middle.

  1. 01

    Tell us

    A few lines and some photos are enough to start.

  2. 02

    We read your drawings

    We tell you plainly what we can see and what is missing.

  3. 03

    Fixed fee, confirmed in writing before we start.

    You know the scope before any work begins.

  4. 04

    Calculations and drawings your builder can build from

    One set for Building Control, one for your builder.
