Our expert single‑storey extensions in Dumfries and Galloway add stylish, functional space, whether it’s for a modern kitchen-diner, a bright new living area, or a home office. As trusted home extension contractors in Dumfries, we bring local knowledge, quality craftsmanship, and seamless end-to-end service to each house extensions project.

What Makes a Single-Storey Extension a Smart Choice?

Single‑storey extensions are popular for good reason: they typically fall under permitted development, reducing planning hurdles, and they often cost less to build than two-storey options. Single-storey extensions in Dumfries offer fast build times, energy-efficient design, and a strong return on value, especially when done well. Clarity in structure, materials, and contractor coordination is key.

What Types of Single-Storey Extensions Can We Build?

At South West Trades, our extension services span:

Rear or side-return extensions—perfect for open-plan kitchens or lounges, maximising your existing footprint
Full-width or wraparound builds—ideal for seamless indoor-outdoor flow and flood-lit living areas
Bespoke designs with rooflights or glass features—bringing in natural light and a modern feel without dramatic structural overhaul

Each is tailored to your home’s style and your lifestyle needs across single storey extensions Dumfries and Galloway. We also offer two storey extensions if you decide to expand the project.

Do I Need Planning Permission or Approvals?

Often, single‑storey extensions come under Permitted Development, meaning planning permission isn't required, especially for rear additions within size limits. However, conservation areas, listed buildings, home type, and dimensions might change things. Building regulations, which safeguard ventilation, insulation, structural integrity, and fire safety, always apply and we handle all compliance and sign-offs for you.
