Customers Garden Rooms Supplied
Another one of our lovely buildings brought to life! Our Royal buildings are the perfect choice for a fully insulted and double glazed year round garden room. Our customers came in to design the building with our sales advisor. This Royal is 10 foot x 16 foot with an apex roof with black felt tiles. The building also includes PVCu windows and door frames in the colour of your choice and Strongcore cladding painted in a Royal Exterior paint. The customer chose to include laminate floor and blinds for the windows also. Our base contractor constructed the heavy duty timber subframe base for the building and will be back to add decking to the base area together and our electrician will visit shortly to add the electrics to the building.
Lovely feedback to receive from our customer who recently had installed our Platinum Odiham 12ft x 10ft pent insulated garden room. Thank you for your comments 😀 ***** 5 out of 5 stars Mr C - December 21st, 2024 Happy with the range of summerhouses seen on site. Quality and pricing is good. It was easy to view and did not feel pressured into buying. Our queries were answered and we went ahead with our purchase, The summerhouse was installed on the date given. No issues. A good shopping experience.
We really did love receiving some photos of our customer's completed building which she's using as a hairdressing salon . The building is our Royal Pent Garden Room 20 foot x 8 foot which comes fully insulated, painted Strongcore, PVCu double glazed windows and doors and designed to our customer's specifications.
One of our customer's recently bought one of our Platinum Winchester Apex Garden Studios 12ft x 8ft. They had the studio painted, ply lined and with laminate flooring in advance at the manufacturer but they also wanted their very own bar to enjoy in there! Which of course we could do for them and what a nice addition to the building.
We always love seeing the finished result! From initial discussions to placing the order and sketching out the customer's desired building and then to actually seeing the building in our customer's garden is so satisfying and why we love what we do! This building is from our Royal range of fully insulated and double glazed garden rooms and is 12 foot x 10 foot with a pent roof which has EPDM rubber roofing as standard. PVCu windows and door frames, laminate floor and painted Strongcore cladding all in colours choices chosen by the customer.
Some lovely photos from one of our satisfied customers! This is one of our Royal Buckingham insulated and double glazed garden rooms measuring 10ft x 8ft. These buildings make great year round buildings and perfect for a home office. Our base contractor also laid our customer's timber subframe base for the building and our electrician has fitted the electrics including an air con unit.

Choosing a 4m x 4m Garden Room: Dimensions, Layout and Uses
An exact 4m x 4m garden room has a footprint of 16 square metres, approximately 172.22 square feet. The nearest whole-foot imperial dimensions are 13ft x 13ft, approximately 3.96m x 3.96m. These sizes are close, but not identical. Confirm the exact external dimensions, overhang and foundation requirements for the selected building.
Compare the four designs below for a configuration around this size. Request a 13ft x 13ft quotation or an exact metric configuration and confirm availability for your chosen model. Framing, insulation and lining reduce usable internal space, and roof overhang adds to the space needed outside.
How should I plan a 4m x 4m garden office?
The square proportions allow desks on adjacent walls or a central worktable, subject to door and window positions. Draw the finished interior to scale and mark each item of furniture. Allow room to pull back chairs, open drawers, and move through the entrance. Plan windows to avoid screen glare, and reserve suitable wall space for storage.
Can a 4m x 4m garden room combine work and leisure?
Yes, if each activity has enough usable space. Keep seating clear of chair movement and door swings. For hobbies or exercise, measure equipment with its operating clearance, not just its storage footprint. A central worktable may suit a studio, while desks around the perimeter can leave space for a separate seating area.
Can two people work inside?
A garden office around 4m x 4m can suit two workstations on separate walls or side by side, depending on the entrance and glazing layout. Check that both chairs can move without blocking the entrance and that you can access the cupboards. Confirm the finished internal dimensions before buying furniture.
Compare Garden Rooms Around 4m x 4m: Request 13ft x 13ft
The following designs have published size ranges that allow consideration of this footprint. Request a 13ft x 13ft configuration, the nearest whole-foot imperial size, and confirm availability and the agreed dimensions in a quotation before ordering. Request exact 4m x 4m measurements if your site requires them.
Platinum designs with optional wall and roof insulation
Compare doors, windows, roof style, cladding, framing and flooring as well as insulation. Check the selected drawing rather than assuming that every design has the same entrance, roof orientation or usable wall space.
Optional Insulation, Glazing and Colour Paint Treatment
Can I specify an insulated 4m x 4m garden office?
Optional wall and roof insulation is available on the models listed above. Confirm the insulation and internal lining package for your selected configuration. Check floor insulation separately; optional wall and roof insulation does not establish that floor insulation is included.
Confirm the doors and windows specification and ask which double-glazing options are available for the selected model. Explore our insulated garden rooms for information on insulation choices, then agree the package applicable to your building.
What else should I plan for regular office use?
Assess heating, ventilation, moisture management, lighting, sockets and an internet connection alongside the building specification. Confirm any electrical installation and other services separately in your quotation. Insulation alone does not control the room’s temperature year-round.
Can I choose a colour paint finish?
Optional colour paint treatment is available. Browse our painted garden rooms and confirm the available finishes for your chosen model. Check colour choices and maintenance guidance, and ask about samples if a precise shade matters.
Assembly Service, Base Preparation and Garden Access Information
Free assembly is included on all our garden rooms and offices. Provide your postcode and access details before ordering so delivery arrangements and any restrictions can be confirmed.
What base does a 4m x 4m garden room need?
Obtain the exact foundation requirements for the chosen model before commissioning work. Prepare a firm, flat and level base with sufficient surrounding installation clearance. Do not build a 4m x 4m base from the category name alone; use the agreed manufacturer’s drawing and foundation requirements for the selected metric or imperial configuration.
See our base preparation and additional garden building services. Base preparation is separate from the included building assembly; confirm availability and costs for your address.
What access should I check?
Measure the narrowest gate and passage along the route from the delivery point to the base. Describe tight turns, steps, slopes, overhead restrictions and any enclosed section so the team can assess access for the panels before installation.
Robin Antill’s Advice and Seeing Garden Rooms Before You Buy
Robin Antill, founder of 1st Choice Leisure Buildings, began working with garden buildings in 1979. His manufacturing and retail experience informs our advice on comparing construction, layout and insulation.
For a square office or studio, start with a measured furniture plan and compare the whole building specification. Check the floor, framing, roof, glazing and insulation, and confirm the exact dimensions of your selected configuration before preparing the base.
Can I inspect representative garden rooms?
Visit our Surrey garden building show site at Sutton Green, near Guildford and Woking to compare representative buildings and finishes. Contact us before travelling if you want to see a particular model or feature, as we may not display every size and configuration.
