Survey & Design
Measured survey, architectural drawings, planning application
We start with a full measured survey of your home. Our in-house architectural team produces detailed drawings and handles the planning application (or Permitted Development notification). You review and sign off every drawing before anything goes to the council.
You always know what's next.
Drag the progress marker to simulate how your project timeline looks at any stage.
Every Hearthstone project gets a live timeline like this. You'll always know what's happening and what's next.
People we've helped.
Real homeowners, real projects. Every quote is verified and tied to a completed build.
“We'd been let down by two builders before Hearthstone. From day one they were different -- weekly updates, a named project manager, and they actually finished a week early. Our extension is exactly what we hoped for.”
“The fixed-price quote meant we could budget properly. They flagged a drainage issue early and dealt with it within the contingency -- no nasty surprise invoice.”
“Living in the house during a loft conversion sounded awful. The site team were tidy every single evening. My kids barely noticed they were there.”
“Four weeks, no fuss. The garage is now the best room in the house. The underfloor heating alone was worth every penny.”
“I was nervous about the structural work -- removing load-bearing walls is stressful. They had the structural engineer on site, explained every step, and the result is stunning.”
“The Gantt chart they provided on day one was still accurate at week six. I've never experienced that level of organisation from a building firm. Would recommend to anyone.”
We work across Nottingham and beyond.
Based in NG2, we cover Nottingham city and up to 25 miles out. We know 1930s semis in Beeston, Victorian terraces in Sherwood, and 1960s detached in Wollaton inside out.
Not sure if we cover your area? Get in touch -- if it is within 25 miles of NG2, we almost certainly do. We can usually confirm within two hours.
