Garden Rooms

Garden Rooms & Studios

Garden rooms are becoming an increasingly popular option for creating more space in a home for a whole range of purposes. With working from home now being the norm for many people, insulated garden rooms are a fantastic office space solution, allowing separation from the main house itself. Aside from an office, other garden room ideas could include using the space for a home gym, playroom, outside living area or bar, music or art studio, therapy room, hobby room, or simply additional storage space. Garden rooms are as versatile as you need them to be.

Looking for some more Garden Room inspiration?


We recently completed this 7.5 x 4m garden room, including everything from drainage and insulation to installing electrics and initial decoration.

This Garden Room has it all! After the initial construction, groundwork and drainage we installed electrics, sorting power and lighting in the space for the clients. The structure is fully insulated in the roof and walls, with radiators and Band A+ energy rated double glazed window units to keep the room as cosy and quiet as possible. We plastered and painted the interior walls as well as installing flooring and skirting boards. This Garden room features EdgeGlide aluminium sliding doors and ALUK aluminium windows (casement and fixed) all in black. The Hardie Plank Cladding is in the colour Smooth Slate Grey.

Our buildings come with a QANW 10 Year Insurance Guarantee and windows and doors come with a QANW 10 Year Insurance Guarantee and CERTASS registered.



Do you need planning permission for a garden room?

In short, the answer is no, you do not need planning permission to build a garden room, so long as they fall within permitted development guidelines. In general, small garden rooms which do not have sleeping accommodation and are a single storey with a max eaves height of 2.5m will not require any planning permission. There are some more restrictions that apply to larger buildings.

How much does a garden room cost?
Depending on the size, design and materials chosen, the cost of a modern garden room will vary.

As a guideline we have provided sizes along with estimated costs:

3m x 2.5m = £10,900 +VAT
3m x 3m = £11,200 +VAT
4m x 4m = £14,500 +VAT
5m x 4m = £20,500 +VAT
6m x 4m = £23,950 +VAT

However we can estimate for any size, so please get in touch.

What is a garden room?
A garden room is usually a small outbuilding that is constructed in the back garden of a property. Modern garden rooms are used for a whole variety of purposes, such as office space, lounging room or therapy space. Insulated garden rooms usually have electricity and lighting, and can be decorated inside like any room in a house.
Do garden rooms add value?
Yes, garden rooms do add value to a property. With working habits changing and many of us being based at home more, garden rooms are growing in popularity and are a unique selling point for homes. Additional floor space and storage room are attractive to many prospective buyers and offer a huge amount of flexibility and versatility for modern living needs. Property experts estimate that modern garden rooms can add anywhere between 5% and 15% to a property’s value.
