Outbuildings

Garden Rooms, Pods, Home Offices, Granny Flats & Annexes

KD Design can help you make the most of your outdoor space by designing versatile outbuildings such as garden rooms, home offices, granny flats, or annexes. Many of these structures can be constructed under permitted development rights, making them a practical and cost-effective way to expand your home.

Garden Rooms & Home Offices

Ideal for work, hobbies, or relaxation, these spaces are usually classed as permitted development, provided they meet criteria for size, height, and location. They remain ancillary to your main dwelling and generally do not require full planning permission.

Granny Flats & Annexes

If your outbuilding includes independent living facilities—such as a kitchen, bathroom, and sleeping area—it may be considered a granny flat or annex. KD Design can advise on planning rules, particularly the distinction between an annex vs. a detached dwelling, where the presence of cooking facilities is key.

Expert Advice from KD Design

With our expertise, we guide clients through planning rules & regulations, ensuring your outbuilding project—whether a home office, garden room, annex, or granny flat—complies with local rules while maximising usable space.

Why Choose KD Design for Your Outbuilding?

There are many prefabricated outbuilding units available, from garden rooms to granny flats, but these can often become expensive and may limit your design options. At KD Design, we can prepare bespoke architectural plans and drawings that allow for site-made structures, which can sometimes be more cost-effective and individually tailored to your needs.

Many builders or off-the-shelf suppliers offer standard solutions that may not make the best use of your space or suit your lifestyle. At KD Design, we take a different approach: we put your needs and your property first, designing outbuildings that work perfectly for you, whether it’s a home office, Garage, or garden room.

Our bespoke architectural design service focuses on creating spaces that are practical, functional, and enjoyable. We consider clever design tweaks and thoughtful features to maximise space and comfort. From integrated storage to bespoke kitchenettes or study areas, these details make your outbuilding not just functional, but a space you’ll love to use every day.
