Insulated Garden Rooms

Insulated Garden Rooms & Summer Houses

The UK may not be known for having the best weather, but don’t let that get in the way of enjoying your time outside. Rain or shine, make the most of your garden all year round with an insulated garden room. Complete with residential-grade wall, floor and ceiling insulation, a Crown Pavilions luxury insulated garden building offers a comfortable and cosy living space, perfect for home offices, garden gyms and recreational activities, such as a games room or crafts studio.

At Crown Pavilions, we offer the very finest in outdoor living, using only the highest grade materials and expert craftsmanship. We also offer more customisations as standard, as well as a selection of upgrades, with a choice of superior quality doors and windows, cladding options, soundproof insulation and more.

Our Garden Room Models

Our range of insulated garden rooms comprises three magnificent models in a range of sizes. The Crown Sandringham offers a sumptuous design to suit a traditional garden landscape, whereas the Crown Clarence features a bold exterior wall for a more contemporary feel. Our Buckingham hybrid model boasts a beautiful covered gazebo area in addition to an insulated summer house. Looking for something specific? Work alongside our designers to create a bespoke build.


Why have an insulated garden room?

A well insulated garden room will provide a space that is warmer in the winter and cooler in the summer. It can also save you money on heating and cooling bills as you will be able to go longer into the year before needing to turn on your heater or engage your air-conditioning. An insulated garden room acts as an extension of your home, providing you with more living space, an extra bedroom or insulated garden office. Perfect for hosting guests, relaxing with family or working from home anytime of the year, an insulated garden building offers a multifunctional space that can be tailored to suit your lifestyle - be that creating a tranquil space to pursue your hobbies or the ultimate entertainment hub to take your social life to the next level.

Best of all, an insulated garden room is built separate from your main dwelling, saving you the hassle of planning permission*, dusty and noisy building sites and a long building process. A Crown Pavilions building can be installed within a matter of weeks with minimal disruption to your home life, compared to alternative home extension methods.

*Please note that planning permission is required in some instances. See our planning permission guide for more information.

Insulated garden studio

Insulated garden studio

Building an insulated garden studio is a cost effective alternative to moving house or a conventional home extension. Since a garden studio is built separately from your main home and is constructed with residential-grade insulation, it provides the perfect place to host guests, house relatives or rent out a room for additional income. Similarly, you need not worry about noisy or dusty building sites disrupting home life, which means you won't need to find temporary accommodation during the building process, saving you time and money. Please note that you may require planning permission if you plan to live or sleep in your garden studio.

Entertainment room

Whether you enjoy cosying up for a movie night, hosting friends and family for dinner or enjoying a tipple or two, an insulated garden room provides the perfect entertainment room. Why not go for our Sandringham model and make the most of an insulated room throughout the winter, and a covered gazebo area to soak up the British sunshine? You could even install infrared outdoor heaters and impress your neighbours with al fresco soirees anytime of the year.
