Large Garden Rooms
LARGE (from 13 - 18 m²)
Discover our large garden rooms.
Large garden rooms provide a substantial amount of additional living space, offering the freedom to create a dedicated environment tailored to your lifestyle. Designed for homeowners who need more room to work, exercise, entertain, or relax, they deliver all the benefits of a traditional extension while maintaining a strong connection to the garden.
Garden rooms and outbuildings over 15m² may require Building Regulations approval, depending on their size, location, construction and intended use. Planning permission may also be required if the building does not meet Permitted Development rules. We can advise you on both before your project begins. As they are built to achieve the same standards as a regular house, these can be utilised as an extension or stand-alone unit. We can help you through the process, get in contact today.
With their generous internal dimensions, large garden rooms can comfortably accommodate multiple functions within a single space. Whether you're creating a professional home office with a meeting area, a fully equipped home gym, a creative studio, a games room, or a stylish garden retreat, a larger footprint allows you to design a space that works exactly the way you need it to.

Large garden rooms are ideal for those seeking a versatile, multi-purpose building that can adapt as requirements change over time. The additional floor area provides room for larger furniture, storage solutions, exercise equipment, or separate zones for work and relaxation, making them an excellent long-term investment for modern living.
Many homeowners choose a large garden room as an alternative to moving house or undertaking a costly extension project. By transforming underused garden space into a practical and attractive living area, a large garden room can significantly enhance both the functionality and value of your property.
