Finding the right drawing design service in Hampshire isn’t always easy — there are a lot of options, and it’s not always obvious what sets one practice apart from another. Here’s why homeowners and developers across Southampton, Romsey, Totton, Lymington and Portsmouth continue to come back to Graham Barker Design for their drawing design needs.
A drawing design service you can genuinely rely on needs to be three things: accurate, clear and fit for purpose. That’s exactly what we deliver at Graham Barker Design. Whether you need drawings for a planning application in Southampton, building regulations approval in Eastleigh, or a full set of construction drawings for a project in Winchester — we produce plans that do exactly what they’re supposed to do.
Home extensions and loft conversions are among the most popular reasons people need a drawing design service — and with good reason. A well-designed extension doesn’t just create more space; it can add significant value to your property. But getting it right on paper first is essential. Our drawing design service covers everything from the initial measured survey through to the final, submission-ready drawings — so you know exactly what you’re getting before anything is built.
The drawings we produce aren’t just technically correct — they’re also clear and easy to follow. That matters for your builder on site, and it matters to the council officer reviewing your application. A confusing set of drawings creates delays. Ours don’t.
Building Regulation Compliance — detailed technical drawings meeting current building control requirements
Free quotations and consultations with no hidden fees
Home Extensions — single and double-storey, rear, side and wraparound
Loft Conversions — dormer, hip-to-gable, mansard and Velux
Planning Permission Applications — drawings prepared to local authority standards
Project Management Services — keeping your build on track from drawing to completion
We cover a wide area across Hampshire — including Fareham, Portsmouth, Andover, Salisbury, Ringwood, Lyndhurst and Lymington. Whatever the size or type of your project, get in touch and we’ll talk you through the options.
Here at Graham Barker Design, we have been helping homeowners and businesses across Hampshire navigate the planning process for more than 20 years. From producing accurate drawing design service plans for planning applications to advising on building regulations compliance — we are your one-stop shop for everything related to design and planning in the region.
Our aim is to make the drawing design process as straightforward as possible for every client. We start with a thorough site survey, then work through the design with you at every stage — ensuring the drawings we produce are not only technically correct, but also practical, compliant and tailored to your project. Whether you need a drawing design service in Southampton, Eastleigh, Fareham or Portsmouth, you can rely on us to provide clear guidance and great results throughout.
No two projects are the same, and the Graham Barker Design team understands that. Our drawing design service has been used by a wide range of clients — from homeowners in Romsey and Totton planning a rear extension, to developers in Andover and Winchester pushing through a commercial planning application. Whatever the scale or complexity of your project, we have the experience and knowledge to help.
The information above should give you confidence that there is no other drawing design service in Hampshire better placed to support your project than Graham Barker Design.

“For a while, I’ve been deliberating over whether or not to sell my property to upgrade to something bigger or extend my existing home for some additional space. After a recommendation from a friend, I gave Graham Barker Design a call and was pleasantly surprised by their friendly and incredibly helpful team. The team have been nothing short of professional and have already exceeded my expectations – and I couldn’t be happier with my new extended home!”
Mr Timothy Carter
“My partner and I have long been considering a loft conversion to create some extra space in our home since our son and his partner moved back after their studies. I’m so glad we reached out to Graham Barker Design, as they made the process so simple from day one. At first, we had no idea what to expect and how our home could accommodate an extension, but now we have a stunning extra double bedroom, as well as a brand new en-suite bathroom. Couldn’t be happier!”
Mrs Edie Francis
“Thank you so much to the wonderful team at Graham Barker Design, who recently helped me to obtain planning permission for a new build project. This was our first attempt, and I was unsure how to proceed. The team were so helpful and were there every step of the way to offer useful advice, and their help has been invaluable. Would highly recommend to anyone embarking on taking their first steps on the property building ladder!”
