4m garden rooms offer light, bright spaces that are perfect for garden office working or simply relaxing. Manufactured in the UK using only sustainable and certified timber, these stylish retreats will provide you with comfortable additional living space suitable for year-round use. The garden rooms you see here feature robust, 72mm double-skinned walls and efficient EcoQuilt insulation, while the tongue and groove wooden floors incorporate Air Tech insulation. Buildings in the Sherwood range have 100mm double-skinned walls, giving even more insulation. Double-glazed windows are fitted as standard, and we provide a 10-year anti-rot guarantee for your peace of mind.

Free installation is included in the package – all you need to do is construct a concrete base for your building and our team of professionals will do the rest. For step-by-step instructions on installing a base for your garden room, see our shed base installation guide. Another alternative is to add an elite timber base with ground screws to your order when you’re making your purchase.

So if you’re looking for a comfortable outdoor building to use as a hobby space, home office, gym, or simply a tranquil spot to relax, a 4m garden room could be just what you’re looking for – but make sure you consider all the options by reading our ultimate guide to buying an insulated garden room.

Do I need planning permission for a 4m wide garden room?

Our 4m garden rooms are designed to meet 'permitted development' rules, meaning you can install them within your outdoor space without having to apply for planning permission.

However, there are various stipulations and exceptions regarding what you can and can’t do with external structures so it’s definitely worth having a thorough read of our article on planning permission for garden buildings to get an idea of all the necessary considerations in complying with the relevant regulations. If you’re in any doubt, check with your local authority’s planning department.

How to furnish a 4m wide garden room

A 4m garden room offers a blank canvas for creating an inviting and versatile space. When considering your options, start with the essentials, incorporating comfortable seating like sofas or lounge chairs to establish a cosy atmosphere. Of course, many of your choices will depend on your room's purpose – whether it's a home office, gym or relaxation haven – but it’s a good idea to opt for versatile furniture that can adapt to various settings, such as foldable tables or modular storage units.

A 4m garden room gives you plenty of space for shelving to showcase plants, books or decorative items, maximising both aesthetics and functionality. You can also utilise rugs to define distinct zones within the space and add a touch of warmth. Consider harnessing natural light with strategically placed mirrors to amplify the sense of openness. Finally, reflect your personal taste through textiles, cushions and artwork to make your garden room a comfortable retreat or workspace that seamlessly complements your lifestyle.

Why buy a 4m insulated garden room from Waltons?

A 4m insulated garden room is an incredibly popular size, and one step up from our cosy 3m wide models. It’s a good fit for a medium-sized garden and adds a smart, modern, focal feature to your outside space. Apart from increasing the value of your property, a good-quality 4m garden room gives you a comfortable space to indulge hobbies like painting, crafting, exercise or yoga.

Cutting-edge multi-foil insulation in the walls, ceiling and floor ensure that your new garden room is a comfortable place to spend time, come rain or shine. The double-glazed windows and lockable door keep your belongings secure, and having all your equipment in a dedicated space allows you to throw yourself straight into work or play as soon as you walk through the door.

The special modular design allows you to customise the final layout of your building. Position the windows and doors to fit your needs, whether that’s to catch the evening light, create easy access, optimise the interior storage potential or frame a favourite view. Landscape your outside space to complement your garden room and your entire property will be enhanced.

What are the best ways to use a 4m garden room?

Improve your lifestyle with a 4m garden room whether you’re a workaholic, gym lover or craft enthusiast. The best thing about installing a garden room is that you get a complete blank canvas in which to work or play away from the noise and hubub of the main house.

Move all your workout gear into your garden room to make a home gym. Install rubber matting, a whiteboard for PBs and a sound system to fuel your workouts. Our garden room interiors are airy with plenty of natural light, making for a much better workout than in a garage or bedroom.

If you want to improve your work-life balance, consider creating a garden office. Free yourself from a busy commute and expensive business rates by creating an office right in your backyard. Separating your workspace from your home helps you to manage your time and focus by improving productivity while also allowing you to close the door on work at the end of a busy day.

Our insulated garden rooms also lend themselves to easy outdoor entertaining and making the most of balmy summer evenings. Line a path with solar lights for guests to wend their way to your magical outdoor dining room, or create a cosy space to relax with a sundowner as evening falls.

Where to site a garden room

Think about the view you want to frame from your new 4m garden room. If you’re going to make it into a home office, you may prefer to face your room away from the house to avoid distractions. Remember to consider the view from the house as well as the view from your new garden room.

If you’re connecting to utilities like water, mains electricity and the internet, think about how far you want to be from the main house. And if you’re not going to be self-contained, think about how far you’re willing to run back and forth for comfort breaks and coffees!

Don’t forget to leave space around your garden room for future maintenance work. Check planning permission rules too, and make sure you put your garden room somewhere that doesn’t require an application. Generally, the rear of the house is the best place.

Once it’s installed, clever planting of shrubs and small trees around your new garden room can help it to blend beautifully into your garden. Whether you want something subtle or decide to paint it a vibrant colour as a stylish centrepiece, with a bit of thought it will transform the look and feel of your entire garden.

Can you run a business from a 4m garden room?

A 4m wide garden room provides the perfect space to start your own business. A 3m x 4m building has plenty of room for light storage, a desk and a planning table. But if you think your company could grow quickly, go for the biggest size your garden and budget will allow.

If you’re working online, you’ll need to get your shed connected to the internet. Hire a professional electrician to help you install mains electricity safely (and make sure you comply with building regs). You may want to think about connecting a water pipe for hot drinks and a handwash basin. Our guide to getting water to your shed can help get you started with this.

It’s always important to consider whether the business will impact your neighbours. While working from home a few days a week is usually fine, you may need to apply for planning permission before starting a business in an outbuilding, so double check with your local council first.

How to look after and maintain an insulated garden room

After your garden room is installed, make sure you treat the outside with a high-quality timber preservative and waterproof top coat as soon as possible. Simply give it a fresh coat every year to keep your 10 year anti-rot guarantee rolling. Our garden rooms are all designed against water ingress and decay, but if you do experience a problem don’t hesitate to get in touch with our team for advice.

The best way to maintain your insulated garden room is to keep a regular eye on the state of your structure. Check the walls, roof and windows for any damage. If you find anything that needs attention, don’t put it off.

Follow the care guidance outlined in your building’s product instructions and the manufacturer’s recommendations attached to your insulated garden room when it arrives.
