3m garden room questions

The questions we're asked most often.

What can I use a 3m wide garden room for?

A 3m wide garden room offers a versatile space for a wide range of activities. You can transform it into a home office, providing a secluded workspace that fosters productivity and creativity. Alternatively, indulge your passion for fitness by converting it into a small private gym or a tranquil yoga room.

As a cosy retreat, your room can serve as a reading nook or an artist’s haven, making use of natural light for inspiration. For small social gatherings, a 3m wide garden room can be your entertainment hub, accommodating game nights, movie marathons, or intimate dinners.

Alternatively, embrace mother nature and use the space as a stylish growing room for cultivating plants and herbs. With its adaptability, a 3m wide garden room is a blank canvas for your own diverse personal interests and lifestyle.

Can someone install my 3m wide garden room for me?

Home installation by our expert installers is included with the price. After your order, our team will be in touch with a pre-installation questionnaire. You’ll need a firm, level base ready, and once your base and garden access have been checked, we’ll contact you to arrange a delivery and installation date to suit you. Concrete or paving slabs work well for the base. You can also add an Elite Timber Base with ground screws to your order. For detailed instructions on how to prepare the foundation, refer to our guide on garden room base installation.

Can I use a 3m garden room all year round?

Yes. These garden buildings are suitable for year-round use, with double-skinned, 72mm thick walls, double glazed windows and insulation in the walls, roof and floor. In much colder months, you may still want additional heating such as an electric or oil heater.

Turn your Waltons garden room into a home office, garden studio or entertainment space.

Why choose a 3m insulated garden room?

An insulated garden room gives you extra space without building an extension.

What makes the insulated garden rooms stand out is that they’re suitable for year-round use, with EcoQuilt insulation and double glazed windows, so you can use the office during the day, entertain in the evenings or work out at any time.

Our cosy 3m wide garden rooms suit smaller gardens. The 3m x 3m garden room makes a light, bright place to set up a desk, craft table or exercise bike, with full length windows letting the daylight in.

If you’ve got extended family to cater for and want to use the space for entertaining, consider a more spacious 5m x 3m garden room. You’ll be able to add a larger table, a sofa and even a drinks area tucked into a corner.

How do I finish and fit out my insulated garden room?

Your garden room is supplied untreated, so once it’s up, apply a high-quality timber preservative and a waterproof top coat, and reapply every year. You can add an exterior paint when you choose your room.

Once your new garden room is up, there’s nothing to stop you from transforming it into a home gym, dream hobby space or home office. Lighting has a big impact on the feel of any interior, so choose whether you want traditional wall lights, multi-colour LEDs or warm hued lamps.

Electrical installations must meet Part P of the Building Regulations. Please use a registered electrician. Find out all you need to know about getting your shed hooked up to the mains in our blog article.

What happens on installation day?

On installation day, our team will call in the morning with a rough ETA. They’ll come and install your garden room on the base you’ve prepared, and clean up afterwards.

What foundation is best for an insulated garden room?

We recommend a paving slab or concrete foundation for your insulated garden room. If completely flat and level, these create a sturdy base to keep your timbers aligned.

It’s always a good idea to get a professional in to make sure you get the best results, but if you feel up to the task yourself, take a quick look at our comprehensive base building guide for the best way to go about it.

Do I need planning permission for a 3m garden room?

Planning rules depend on your property and where you live, and they differ in Scotland, Wales and Northern Ireland, so please check with your local planning office before you order.

How do I connect a garden room to the internet?

You can connect your garden building to the internet in a few different ways. It’s quickest to simply use mobile tethering to get online in your garden shed but if you need lots of data to download big files and video call, consider a more permanent option like extending your current home WiFi or laying an ethernet cable.

Read our guide to getting your garden building online for tips on how to get your garden room connected.
