What we build

Residential and light commercial work. Every job has a named site manager from day one.

  1. 01

    Extensions

    Single and double-storey extensions, designed with your architect or ours.

  2. 02

    Loft conversions

    Dormer, hip-to-gable and mansard lofts, from steelwork to staircase.

  3. 03

    Renovations

    Whole-house refurbishments planned room by room, so you can stay living in it.

  4. 04

    New builds

    Individual homes and small developments, from groundworks to keys.

  5. 05

    Commercial fit-out

    Offices, shops and studios fitted out around your opening date.

  6. 06

    Groundworks

    Foundations, drainage and landscaping done properly before anything goes up.

One extension, start to finish

What a two-storey rear extension looks like at each stage — and what gets checked before the next one starts.

Opening up

The back of the house is opened up and new steel beams take the load, so the kitchen can run straight through to the garden.

CheckedBuilding control inspects the steels before anything is boxed in.

Drawings first.

Before a brick is laid, you see exactly what changes. Drag across the elevation to compare the house as it is with the extension as quoted — the same drawing your site manager works from.

Details you’ll live with

The quote names every material. These are the four we’re asked about most.

    Graded studs and joists, wrapped against the weather and fixed to the engineer’s schedule.

    Two coats, given time to dry before any paint goes on — the step that saves a repaint later.
