Quality you can rely on
We’re led by over 20 years of construction experience, including a regional LABC award for best commercial build. That same standard is behind every DWG project today, backed by a 12-month workmanship guarantee, so if something’s not right after you’ve moved back in, it gets put right.
Clear pricing from the start
Once we understand what you want to achieve, you get a detailed, itemised quotation before anything’s agreed, so you know exactly what you’re paying for.

One person, start to finish
We keep one experienced point of contact on every Bedford project, from the first conversation through to handover, so you always know who’s responsible and where things stand.

Questions about building in Bedford
If your question is not covered here, ask us directly.
Ask us directly 07928 100884Do I need planning permission for an extension in Bedford?
Not always. Some extensions fall under permitted development rights, others need planning permission, depending on your property, the size and position of the extension, and any restrictions affecting your home. We establish this early, and where an application’s needed, we coordinate the process with Bedford Borough Council on your behalf.
How will you price my project?
Every project is different, so we price the work properly rather than relying on estimates or square-metre rates. Once we understand what you want to achieve, you get a clear, detailed written quotation before construction begins.
How long will the build take?
It depends on the size and complexity of the project and the approvals needed beforehand. You’ll get a clear programme before we start, and we keep you informed as it progresses.
Can we stay in the house while the work’s carried out?
In many cases, yes. There will be periods of disruption, particularly where new and existing parts of the house come together, but we plan around that with you before work begins.
Ready to talk about your project?
Get in touch and we’ll arrange a time to visit your home, discuss your plans and give you an honest view of what’s possible, no obligation.
