What Is A Garden Room?
A garden room (also called a garden studio) is a double glazed garden building that can be attached to your house like a conservatory but is most often found as a standalone structure in the garden. Traditionally, timber garden rooms have been the most common. However, modern garden rooms are also available in uPVC, aluminium and other materials depending on your needs, preferences, and budget.
A garden room is built as a standalone structure, an insulated building, with double glazed windows and usually double doors, totally self-contained away from the main property. Garden rooms are popular because of their privacy and versatility; they can be used in a vast number of ways, depending on what you and your family are looking for in a bespoke extra space. Any additional features will impact the cost of your garden room, so it’s important to understand the various different elements and how these might increase the garden room price you are quoted.

What Affects Garden Room Prices?
Double glazed and insulated garden rooms are solid, versatile, structures with a concrete base that you can enjoy all through the year. Warmth, comfort and energy efficiency are bound to be top of your tick list, and the best way to ensure maximum thermal efficiency is to invest in the right doors and windows using high quality materials and glazing. This will also enhance the aesthetic appeal of your garden room, upgrading your home environment, and appealing to potential buyers when you come to sell your house.
Many people add additional windows to their garden room design, creating a studio or conservatory effect. This fills the space with natural light and allows you to benefit from plenty of fresh air in the warmer months. The construction and what you have inside will all impact the price. Smaller windows rather than floor to ceiling or large windows will cost less, and if you’re installing a garden kitchen or a pod with a bedroom and bathroom, this may suit your needs better. If you’re using the garden building as an office then you’ll probably want to maximise daylight, fresh air and garden views.
Another important consideration in a garden building are the doors. Double doors create a feature entrance and exit and are the perfect choice if you tend to use the room mainly in the summer months. However, they do reduce the available wall space for fixtures and storage. Despite the extra cost, always choose the best quality doors you can afford for energy efficiency, design and security. Let’s take a look at different doors for garden rooms in more detail.
Sliding Doors for Garden Rooms
Contemporary sliding doors for garden rooms bring a reliable and modern design to your new space. Sliding doors have been chosen as patio doors by homeowners for many years and are enduringly popular; it’s a style that transfers well to garden rooms and garden offices. Sliding doors are the most cost-effective choice for your garden room and marry practical features with traditional styling and appeal. Also, the frames are available in a vast range of materials and finishes including wood to complement wooden garden rooms.
Bifold Doors for Garden Rooms
Bifold doors have seen a recent surge in popularity for home extensions and conservatories as well as garden rooms. Bifold doors allow you to maximise the amount of space you have, as they fold away neatly on their tracks in a concertina style. Installing them is simple and straightforward. However, most bifold doors will need to stack on the inside of the garden room, so they may not be the right choice for smaller spaces. However, larger garden rooms will benefit from this design plus it’s right on trend!
French Doors for Garden Rooms
French doors bring a touch of continental charm to garden offices and buildings. They open out into the fresh air, and allow you to benefit from an influx of natural light. Slim frames and an elegant symmetrical styling make French doors a great choice for a more traditional garden structure, blending well with a classic new build or period property.
What Can You Use Garden Rooms For?
Garden rooms can be used for a multitude of different purposes, making them an ideal investment for all types of homes.
A garden room is a great space to relax and unwind in a quiet area at the bottom of your garden, away from the hustle and bustle of the main house. You might want to create a vibrant social hub to welcome friends and family for dining and entertaining with an outdoor kitchen feature, or perhaps you want an extra bedroom and bathroom for family overspill or to welcome guests. With hybrid and home working more popular than ever today, many people have installed a garden room to create an office space that’s distinct from their living areas. If you want to start a business, garden rooms make a great studio space or dedicated area away from the noise and clutter of family life.
Garden rooms are ideal for homeworkers and entrepreneurs. They are a quiet, inspiring and completely separate place to go and work. Equally, as the line between work and home becomes blurred, many homeowners are looking for a place to escape to, separate from their houses. Garden rooms are ideal for this.
The cost of a garden room is well worth the initial investment because it encompasses a wealth of opportunities for you and your home. Here are some of the most inspiring garden room ideas.
- A home office or studio for employment or a new business venture
- A social hub for family and friends with an interior geared to dining or even another kitchen
- Compact accommodation for guests and family when they come to stay
- A home gym or wellness retreat for yoga and meditation
- A dedicated games room or multi-media space for all the family
- Just a garden room with beautiful views and comfortable furniture for down time and relaxing
Because a garden room has a proper concrete foundation and is well insulated with double glazed windows and doors, you can enjoy this space year round so try to think of a function that will benefit you throughout the year, too.
Why Is Double Glazing Essential For Your Garden Room?
You want your new garden room to be secure, durable and energy efficient. Highly sought after because of the way they combine an inside space with the outside world, you can heighten this impact by the use of windows and sliding or patio doors. This bespoke new room can be tailored to your design, with plenty of windows to welcome fresh air for a light, bright and airy space.
It’s vital to choose double glazed doors and windows for your new garden room with the right energy efficiency and insulation, so you can enjoy the space all year round in comfort, and make the most of the opportunities this extra room creates.
Insulated garden rooms with double glazing are designed to retain heat in the winter to prevent higher energy bills, whilst also protecting you from excessive heat in the summer.

Frequently Asked Questions
Can I install a toilet in my garden room?
Yes, you can add a bathroom, ensuite or shower room with toilet to your new garden room plan. These services increase the price because of the cost of the fixtures and the installation. Bathroom facilities are the perfect addition if you want to run a business from your garden room, are designing a home gym, or creating additional accommodation for the family.
Do I need planning permission for a garden room?
Typically, garden room construction falls within what’s called ‘permitted development’ so providing you stay within certain criteria regarding size, height and distance from your boundaries, then you won’t need planning permission. Sizeable garden rooms or those intended for business use will require planning permission. Also, if your home is listed or in a conservation area, then you will need to get special authority for your planned installation. Always check with your local authority if you are unsure about the installation.
How long does it take to build a garden room?
The construction time for a garden room varies depending on its size, the complexity of the installation, the services required and the interior finish. Once on site, most contractors will complete the build within 2-6 weeks. However, busy installers will have a lead-in time before they can start your project.
Are garden rooms thermally-efficient and sustainable?
Modern garden rooms are designed with energy efficiency front and centre. Insulated walls and roof covering combined with double or triple glazed windows and doors, maintain an even temperature year round protecting your energy bills and ensuring optimal comfort. Your installer can discuss a bespoke insulation package that reflects your proposed use so that you can maintain an appropriate temperature in your new garden room regardless of the weather outside.
Can I use my garden room as a home office if I run a business?
Yes, but you will probably need planning permission first. A garden room makes a super internal space for a home office or a dedicated workplace for a business. Check first with your local planning authority. You’ll need to discuss this with your mortgage provider and household insurer. If you intend to allow public access, then you must have public liability insurance too.
