Thinking of a Garden Room or Sun Room in Weymouth? Here's How We Can Help

If you're considering adding a garden room, sun room, or similar standalone space to your property in Weymouth, now is the perfect time to explore your options.

At Rosenkelly Architectural Design, we specialise in designing high-quality, planning-compliant outbuildings and extensions that add genuine value to your home. Whether you’re after a quiet retreat, a hobby space, or a self-contained annexe for family use, we can help turn your ideas into a fully approved project.

Why Build a Garden Room or Sun Room?

Adding a garden room or sun room offers a range of benefits:

Additional living space without the need for a full extension
Year-round usability with the right orientation and insulation
A bright and comfortable setting for work, relaxation or hosting guests
Potential for future adaptability, including accessible layouts

Depending on your location, design and intended use, planning permission may or may not be required. As a ARB-registered architect based in Weymouth, we are well placed to advise on what is possible for your property and to guide you through the process if an application is needed.

Recent Success

We’ve recently secured Householder Planning Approval for a new detached annexe building in Weymouth that replaces two outdated garden structures. The design remains modest, accessible, and fully integrated with the main dwelling. It provides an ideal model for anyone thinking about a high-quality, low-impact garden building.

How We Work

From initial feasibility to planning applications and Building Regulations, we offer a clear, staged service. You’ll receive tailored advice specific to your site, along with drawings, technical coordination, and all necessary submissions to Dorset Council.

We also offer pre-application services for those unsure about their options and work closely with trusted surveyors and consultants when required.
