DRG 07 · About us
Why homeowners use us
Moving house costs stamp duty, solicitors and estate agents, with nothing to show for it at the end. Extending, or converting the loft or garage, adds space and value to the house you already have.
We have been designing extensions for over 20 years, and working with the planning and Building Control departments across the North West for just as long. We draw everything in CAD, keep our fees fixed and stay with you until the drawings are approved.

Planning, permitted development and fees
Do I need planning permission for an extension?
Not always. Many single storey rear extensions, loft dormers and garage conversions can be built under permitted development, within limits on size, height and materials. Two storey extensions, conservation areas, listed buildings and flats need planning permission. We tell you which route applies at the free survey.
How long does a planning application take?
Usually six to eight weeks from when the council validates the application. It can take longer if the planning officer asks for changes. We handle the officer's questions for you.
Will I need to do anything for the application?
No. We prepare the drawings and forms and submit the application on your behalf. You approve the design and pay the council's fee.
How much do extension plans cost?
Planning drawings start at £525 + VAT and Building Regulations drawings at £295 + VAT, depending on the project. Every fee is fixed and confirmed after the free survey. The council's own fees are extra.
What drawings will I get?
For planning: location and block plans, existing and proposed floor plans and elevations. For Building Regulations: a site plan, floor plans, elevations, sections, construction details and a written specification your builder can price from.
Do you provide structural calculations?
If your design needs them, for example for steel beams or new openings, we source them for you and include them in the Building Regulations submission.
Can you recommend a builder?
Yes. When the drawings are approved we can invite local builders we have worked with to price your project, so the quotes are all based on the same drawings.
Which areas do you cover?
We are based in Swinton and work across Manchester, Salford, Stockport, Trafford and Cheshire. Clients in our reviews come from Chorlton, Timperley, Poynton, Wigan, Worsley, Marple and Salford.
