Design and build in Cardiff

One team from first sketch to finished building: design, planning, construction and finishes, with one point of responsibility.

Design & build at a glance

  • One point of responsibility

    Design and construction sit with the same team, so there’s no gap between what was drawn and what gets built.

  • Planning to completion

    We work through planning with you, then deliver the build. Our five-apartment scheme near the city centre went through planning in 2026.

  • Heavy work handled

    Demolition, new foundations, steels and extensions are part of the job, not something we pass on.

  • Flexible handover

    We can deliver a fully finished building, or do the heavy work and hand over for you to furnish and decorate, as on our Cathays flats.

How design and build works

With design and build, one company takes responsibility for both the design and the construction. You agree the brief and budget with us at the start; we coordinate the design, help steer the project through planning and building regulations, then build it.

It suits clients who want a single point of contact and fewer handovers between consultants and contractors, particularly on conversions and small developments where design decisions and buildability are closely linked.

Flat conversions and small developments

Our design and build work in Cardiff includes:

  • A four-flat development in Cathays: every floor taken out, the rear annex demolished, new foundations, services and steels, a double-storey extension and a dormer with two bedrooms and a bathroom. See the project.
  • Five apartments in Roath, near the city centre: planning approved in 2026, with the strip-out under way. See the project.

What to expect

We start with a site visit and a frank conversation about what the building can realistically become. From there we agree scope, design and budget, and keep you updated through the build with photos and site visits.

If you’re an investor, design and build can be part of a turnkey investment, where we also help with sourcing and handover.

Questions

Design & build: FAQs

All FAQs

Do you handle building regulations?

Building regulations approval is needed for most structural work, extensions, loft conversions and HMO conversions. We coordinate the drawings and building control inspections as part of the project, so you’re not left chasing sign-offs at the end.

What does design and build mean?

One company takes responsibility for both the design and the construction. You agree the brief and budget with us at the start, we coordinate the design, planning and building regulations, then build it. It means one point of contact and fewer handovers.

Can you help with planning applications?

Yes. We work through planning with our clients as part of design and build projects. Our five-apartment scheme in Roath, near the city centre, was approved in 2026 after a long process of back and forth.
