Single Storey Extensions
Single Storey Extension Builders in North Yorkshire – Quality from the Ground Up
At R.M.Contracts (Yorkshire Ltd), we design and build bespoke single storey extension projects for homeowners across North Yorkshire, including Harrogate, Ripon, Wetherby, Otley, Ilkley, Spofforth, Pateley Bridge, Tadcaster, Boston Spa, Knaresborough, Horsforth, North Leeds and Boroughbridge. Whether you’re adding a kitchen-diner, rear lounge or utility space, we’ll turn your plans into a warm, energy-efficient and beautifully finished extension.
With decades of local experience, we manage the entire process—from foundations and structure to roofing, finishing and external works. We tailor every single storey extension to the home’s style, layout and surroundings, ensuring it blends perfectly with the original property.
All work is carried out by our in-house team of builders, joiners, roofers and roofing contractor specialists. That means fewer delays, no subcontracting, and a trusted team you can rely on.
Full Design & Build Service
Every single storey extension starts with a discussion about your space, goals and budget. We then help with design advice, planning permission (if needed), and build schedules that minimise disruption.
We handle:
Foundations and drainage
Structural walls and insulation
Roofing systems, including flat roofs, fibreglass roofs, and GRP roofs
Brickwork, house pointing, render or stonework
Windows, doors and rooflights
All external detailing, including fascias and soffits, and gutter replacement
Roofing Included – Seamless and Secure
Unlike many builders, we specialise in full roofing services — so your new roof is installed correctly and integrated with the rest of the property. Whether your extension needs a pitched finish with new roofs, or a modern flat design, we’ll deliver long-lasting protection that looks great.
We also inspect and upgrade adjoining areas as needed, offering roof repairs and chimney repair to ensure your whole roofline is watertight and up to spec.
Trusted by Local Homeowners
We’ve delivered successful extensions across homes in Ilkley, Boston Spa, Horsforth, Knaresborough, Ripon and beyond. Our clients choose us because we’re clear, consistent and committed to quality.
We don’t cut corners or leave you to chase other trades. Every stage is handled by our team—whether it’s structural work, interior joinery or finishing touches. You’ll always know who’s on-site, and we’re happy to talk through options at every step.
Add Value & Live Better
A well-built single storey extension does more than add square footage—it transforms the way you live. From open-plan kitchen spaces to peaceful rear lounges or playrooms, we help you get more out of your home without the stress of moving.
And if you’re planning future upgrades like dormer loft conversions, our team can factor in services and structure now to simplify the process later.
