Garden Room Extensions Explained

Garden room extensions are an excellent way to expand your living space while maintaining a connection with the outdoors. These modern outdoor structures can be designed as an entertainment space, outdoor kitchen, or even a serene retreat.

In this guide, we will explore the key aspects of garden room extensions, including costs, permissions, attachment possibilities, and whether they can serve as living spaces.

A garden room extension is a versatile, semi-permanent outdoor structure designed to enhance the living space of a home. Unlike traditional conservatories, these modern extensions are constructed using durable aluminium frames, gables and glass panels, providing a contemporary look with optimal natural light.

Our garden room extensions can be customised with features like retractable awnings, heating, lighting, and screening to make them suitable for year-round use. They serve various purposes, including dining areas, outdoor lounges, home offices, and entertainment hubs.

The cost of a garden room extension in the UK varies depending on size, materials, and additional features. On average:

• A basic garden room with heating and lighting ranges from £15,000 to £25,000. This design would include glass panels and a glass roof for year-round use.
• A premium garden room with bespoke designs, smart technology integrations, and add-ons such as a retractable awning can cost £30,000 or more.

Investing in a well-constructed garden room extension can increase property value while providing a functional, stylish outdoor space to enjoy.

In many cases, a garden room extension falls under permitted development rights, meaning planning permission is not required. However, there are certain conditions:

• The structure should not exceed 50% of the total land area around the house. This ensures that the extension does not dominate the outdoor space, preserving garden usability.
• It must not be higher than 2.5 metres if within 2 metres of a boundary. This prevents overshadowing or privacy issues with neighbouring properties.
• If freestanding, the maximum height is 4 metres with a dual-pitched roof or 3 metres with a flat roof. This restriction helps maintain aesthetic harmony and prevents excessively tall structures.
• If attached to the house, it must comply with building regulations. This is to ensure structural integrity, safety, and energy efficiency.
• The intended use of the garden room can affect planning permission. If the space is used as a permanent living area or includes facilities such as a bathroom or kitchen, it may require additional approvals. It’s always best to check with your local planning authority to ensure compliance with specific regulations.

Yes, a garden room extension can be attached to your home, serving as a seamless transition between indoor and outdoor living. When attached, these structures operate like a modern sunroom or glass extension, enhancing both appearance and functionality.

They can be designed to complement the existing architecture and can include sliding doors for an open-plan feel. However, if the extension affects structural integrity or insulation, building regulations may apply, hence professional guidance is recommended.

While a garden room extension can be heated and equipped for comfortable year-round use, using it as a permanent residence requires planning permission and compliance with building regulations.

To be classified as a habitable space, the structure must meet insulation, ventilation, and energy efficiency standards. Nonetheless, for occasional stays, guest rooms, or home offices, a garden room extension is an excellent solution.

Garden room extensions have become an increasingly popular choice for homeowners looking to maximise their living space without committing to a full-scale home renovation. Our high-quality aluminium frames and glass panels turn these modern structures into luxurious yet functional spaces to any property.

By understanding the costs, permissions, and potential uses, you can make an informed decision and create a stunning garden room extension that adds value and comfort to your home.
