How much does a garden room cost? 

Why do the costs vary between different companies?  Which garden room is right for you?  A Comprehensive Guide to Garden Rooms... 

The cost of a garden room can vary significantly and is influenced by several key factors such as size, materials, and additional features. According to The Garden Room Guide, the average cost of a 3 m x 3 m garden room in the UK stands at approximately £21,632, or £2,403 per m2 inclusive of VAT and installation. However, the following factors primarily drive these costs:

1. Foundations: The type of foundation needed can affect the price, with options ranging from concrete bases to ground screws.
2. Materials: The choice between aluminium or uPVC doors and windows, along with the type of cladding, significantly impacts cost.
3. Inclusions: It's important to check what's included as standard. Are foundations and electrical connections part of the package?

The great thing about garden rooms is that you can customise the design to fit your budget and our advice is to check what the garden room company includes as standard. 

Why are Garden Rooms expensive?

When evaluating the cost of garden rooms, it's essential to consider the alternatives. Many families love their current homes, and appreciate their local community and schools, but find themselves needing more space. The traditional solution—moving to a larger home—comes with a hefty price tag, especially in the South East of England. Between stamp duty, legal fees, moving costs, and more, the expense can easily surpass £60,000, not including the higher price of the new property itself. If you want to assess how much it would cost you to move the Barclays Bank website has more information on this and the Government’s stamp duty calculator will help you work out how much Stamp Duty you’ll pay. Garden rooms emerge as a compelling alternative in this context. They offer a way to add that much-needed extra space without leaving your home or dealing with the financial and logistical strains of moving. For a 5m x 3.5m garden room, costs range from £30,000 to £37,000—a fraction of the cost of moving, with the added benefit of adding value to your home.  

  For those with a tighter budget, around £10,000, there are still options like log cabins or summer houses. While these can provide a more cost-effective solution, it's important to consider their longevity and what you plan to use them for. The primary distinction lies in their construction makeup which usually consists of locking the wall logs into one another, slotting in the windows and doors, and then fitting the roof timbers, before nailing in the roof boards and then the floorboards.  They are not as well insulated as a garden room and won’t last as long, however, depending on what you plan to use it for, it may be the right choice for you and your budget.   

In essence, garden rooms represent a smart investment in your current property, enhancing your living space without the overwhelming costs and hassle associated with moving. Whether your budget is big or small, there's a garden room solution that can meet your needs, providing lasting value to your home and lifestyle.

 

Why are some garden rooms cheaper than others?

The difference in garden room prices can often be traced back to the quality of materials used and the construction process. High-quality materials and meticulous design play pivotal roles in ensuring the durability and functionality of your garden room, impacting the overall cost. Established garden room companies, leveraging years of experience and customer feedback, have refined their designs to offer superior quality and efficiency. This expertise allows them to provide extended warranties, affirming the longevity and value of their garden rooms. On the other hand, opting for a local builder might present a cost-effective alternative initially. These savings are usually due to lower overheads, as local builders typically don't incur the same expenses as larger companies, such as maintaining a showroom or extensive marketing campaigns. However, it's crucial to consider the long-term reliability and availability of support should issues arise post-construction. While a reputable local builder can offer a satisfactory outcome, the absence of a long-term guarantee might pose risks. Choosing between a specialised garden room provider and a local builder boils down to prioritising between upfront savings and the assurance of quality, durability, and ongoing support. If reliability and a warranty are paramount for your peace of mind, investing in a garden room from a seasoned company might be the wisest choice.

Before we look at the materials and the factors that affect the cost of a garden room, it's important to let you know that My Retreat only makes timber frame garden rooms with EPS insulation, of all shapes and sizes, with steel frame floors, an EPDM rubber roof, electrical connection to your house, concrete pile foundation and a plaster finish as standard. However, we do offer alternative foundations and insulation types in our bespoke range.  The reason we are letting you know this is because this method may not be the best choice for everyone and this article takes an honest look at the pros and cons of each, allowing you to make the best choice for yourself. 

The key factors that affect the price of a garden room:

Labour:

The cost of labour significantly influences garden room prices, with two primary factors at play: location and expertise. In regions like the South, where the cost of living is higher, labour charges tend to be higher. More importantly, the skill and experience level of the craftsmen—be it installers, joiners, or carpenters—also dictate the cost. Seasoned professionals, with their ability to deliver exceptional quality and efficiently navigate through challenges, naturally command higher fees. This expertise ensures a superior finish and durability of your garden room. While hiring a company from a different area might seem cost-effective, consider the logistics and feasibility of post-installation support and problem resolution.

Garden Room Materials:

The outward appearance of garden rooms can be deceiving, as the true value and durability lie in the materials used beneath the surface. The choice of flooring frame materials that come into contact with moisture, the construction of walls and roofs, and the quality of insulation, doors, and windows all play critical roles. High-quality materials that withstand the test of time and elements contribute to the overall cost but also ensure the garden room's longevity and efficiency. The headline price of a garden room often doesn't reflect the full story, emphasising the importance of understanding what's included in the price and the construction specifics. In essence, when evaluating garden room costs, it's crucial to look beyond the surface and consider the long-term value provided by skilled labour and quality materials. These elements are pivotal in ensuring that your garden room remains a cherished and durable extension of your home for years to come.

2. Garden Room Electrical Connection:

Is the connection to your home's electricity included? Different companies have varied policies; some require you to arrange for electricity to be extended to the garden room's location, while others provide a specific amount of cabling. A professional electrician will need to link your garden room to your home's main electrical panel, typically requiring a 32-amp connection. Ensure there's available capacity on your consumer for this addition, otherwise, you’ll pay around £600 for a new consumer unit.

3. Garden Room Internal Wall Finish:

Some garden room companies opt for a durable, easy-to-clean melamine lining for the interior walls. This type of PVC cladding, commonly used in healthcare settings, is both cost-effective and quick to install. Alternatively, a plaster finish offers a look in-keeping with your house but comes at a higher cost and necessitates a longer installation period due to drying times. Additionally, consider whether the service includes a base coat of paint on the plaster, which can be challenging to apply due to its absorbent nature. Some companies may offer a finished paint as an upgrade, while others may leave the walls primed for your final decoration. 

4. Garden Room Roof type:

Flat roofs on garden rooms typically feature EPDM, a durable, low-maintenance rubber material made from recycled tyres. Another option is insulated metal roof panels, which are both economical and functional. However, this choice often means that electrical wiring and lighting fixtures must be mounted on the surface, concealed by white trunking, to accommodate the roof's structure.

EPDM Rubber Roof vs Insulated Metal Roof: Pros and Cons

EPDM Rubber Roof

Pros

1. Remarkably long-lasting with superior resistance to weather conditions
2. Contemporary and stylish appearance
3. Comes with a 20-year warranty and can last up to 50 years
4. Outstanding resistance to ultraviolet rays
5. Efficiently absorbs and retains warmth
6. Simple to repair
7. Eco-conscious choice, crafted from recycled car tyres that would otherwise contribute to landfill waste.

Cons:

1. Vulnerable to punctures or tears from sharp objects, such as tree branches
2. Lacks significant resistance to fire.

Metal Roof

1. Remarkable strength and longevity
2. Economically advantageous
3. Can last over half a century
4. Requires very little maintenance
5. Eco-friendly, typically crafted from materials that can be recycled.

Cons:

1. Electrical fixtures and lighting on the roof might need to be externally mounted, with trunking utilized to conceal wiring
2. Metal roofs may amplify noise during intense rain or hail, potentially disrupting your concentration
3. Prone to dents if an object falls on them.

5. Garden Room Electrics:

The specifics of internal electrical setups vary from one company to another. Typically, packages include white switches, a designated number of sockets, an electric heater, and spotlights. There's often an opportunity to opt for upgrades, such as chrome or black finishes for sockets and switches. A crucial aspect to consider is the type of electrical installation provided: recessed (where sockets are embedded into the wall, with wires hidden behind plasterboard, mirroring standard household electrics) versus surface-mounted. Surface-mounted electrics involve a network of channels and boxes for attaching lights and outlets externally, without the need to alter the wall structure. This method is cheaper and offers flexibility in electrical layout but involves visible wiring encased in trunking.

6. Garden Room Flooring

Most garden room companies will include flooring, but worth checking what they use. Laminate flooring is cost-effective and is now so good that it is often mistaken for wood, whilst being easy to clean and warm underfoot.

How is a My Retreat Garden Room made? 

We spoke above about the different things that affect the cost of a garden room. Now it’s time to look inside our garden rooms to see what materials we use and why.

Floor: Our garden rooms have a powder-coated, steel-frame floor with adjustable feet. This allows us to overcome any uneven surface, but the BIG thing is that steel doesn’t rot, unlike timber giving you a solid floor for years to come. If you place timber on or near the ground, after a number of years it will rot.

Walls: Our walls are constructed from timber frames with 50mm Foam or EPS (Expanded Polystyrene) insulation so that it is lightweight and easy to carry. We construct them in our production facility in the UK to ensure quality control. They are also made in a cassette format which means our garden rooms are quicker to construct, which saves on labour and helps to keep the cost down for customers, meaning that we can spend more on other materials that make a difference. The other benefit is that the garden room can be carried through a house or a flat if there is no side access. 

Doors & Windows: We use quality windows and doors from Deceuninck who are at the forefront of innovative, high-performance windows and doors. They supply award-winning PVC-U to the trade & commercial sectors. We could use cheaper alternatives, however, the issue is that replacement parts can be hard to find and the quality isn’t the same. All our doors and windows have matching colours on the inside and out, either black on the outside and inside or anthracite grey on both sides. Sure, we could save money and go for cheaper doors that are white on the inside, but it doesn’t give the same lovely finish to a garden room. 

Flat EPDM Roof: EPDM offers a long-lasting and low-maintenance approach to domestic flat roofing. With a life expectancy of more than 50 years, EPDM could outlive some buildings. EPDM delivers 100% waterproofing performance over its expected lifespan of over five decades and requires little or no maintenance once correctly installed. 

1. Impressive Durability
2. Easy to work with
3. Practically no maintenance
4. Environmentally Friendly

2. Hidden door - this is where the single door, usually to a storage room is clad with the same cladding as the garden room to hide or conceal the door for a clean look.
3. Aluminium doors rather than UPVC, are essential if you choose bifold doors. UPVC bifolds in a timber frame always need adjusting which is why we don’t offer them. 
4. Roof Overhang/Extension - Add a canopy at the front with spotlights for a unique look and bit of shelter from the elements. It's possible to add on one, two or three sides, with or without spotlights
5. Wall Extension - perfect if you want to close off one or both ends of the roof overhang for privacy and/or to create a unique design
6. Canopy - perfect cover for your outdoor furniture, hot tub or outdoor BBQ
7. Decking - choose from a range of colours and sizes
8. Windows - UPVC or aluminium in 4 standard sizes, opening or fixed
9. Internet - we understand that some people's internet reaches the garden room or they have boosters. However, if yours does not you can choose a CAT6 data cable that is connected to your router to give your garden room its own wifi zone and the same speed as in your house, perfect for those using it as a home office, kids playroom or gym. We also offer outdoor heaters, sockets, as well as a range of different coloured switches and sockets. 
10. Sizes - whilst our panels come in standard sizes to keep the cost down, we do offer a bespoke option and can make panels to any size if you need a particular sized garden room.
