Buying Guide - Insulated Garden Rooms

Insulated garden rooms offer a quick, easy, and cost-effective alternative to a home extension. Enjoy usability throughout the year with these premium buildings which stay cool in summer and warm in winter, making them a practical and functional space for any purpose. Whether you’re planning on transforming yours into a home office, entertaining space or perhaps a personal gym, these premium buildings are designed for versatility to suit your family’s needs.

1. What is an Insulated Garden Room?

As Mercia’s most premium product range, insulated garden rooms provide year-round usability, complete with exquisite features and details that will elevate your space.

Shiplap+ Cladding

Used for exterior wall panels, Shiplap+ cladding is manufactured using strong and thick 16mm interlocking tongue and groove boards that offer an unparalleled finish. The unique design gives the boards added support for strength and weatherproofing, creating a tight seal against wet weather.

Insulation

All wall panels are insulated using EcoQuilt, a revolutionary foil-coated and breathable foam membrane which, thanks to its minimal thickness, provides plenty of insulation without sacrificing internal space. Providing thermal values equivalent to over 100mm of fibre insulation, this material is assembled with six layers of thermowadding, a breathable foam membrane which also acts as a vapour control layer, and is finished with a coating of highly reflective foil.
As well as wall insulation, all Mercia garden rooms are manufactured with insulation in the floor and roof. This maximises the building’s insulating properties to ensure you can use the building throughout the year, keeping you warm in winter and cool in summer.

Floors

Fitted on top of a strong, secure frame, the floors of our insulated garden rooms are made from 16mm tongue and groove board. This robust material is designed to support the weight of furniture and easily withstand daily use, making it the perfect choice for these premium products.

Roof

Each garden room is equipped with a solid sheet board roof, clad with 12mm interlocking tongue and groove board on the interior. To protect against wet weather, the roof is covered with high-quality roofing material which extends the life of the garden room.


Windows

All garden rooms are supplied with 14mm double-glazed windows and doors as standard. Not only does this provide a greater level of security, it also helps to keep your garden room warm during the cooler months.

7. Which garden room is best for you?

Investing in an insulated garden room is a big decision, not only for the present but also for the long term. It is crucial to carefully consider which garden room aligns with your current needs while also anticipating how it can accommodate your future requirements. The grid below outlines Mercia’s insulated garden room collections to help you choose the style, size and design perfect for you.

 
8. Planning permission and installation

All Mercia insulated garden rooms are designed to meet the official criteria for ‘permitted development’ to avoid the need for planning permission. However, before making any purchases, we recommend verifying with your local planning office for complete peace of mind. Planning guidelines restrict any garden building from occupying at least 50% of your garden without planning permission. For those considering long-term accommodation or the addition of utilities like mains power, water, and drainage, adhering to building regulations is crucial.

All garden buildings must be installed on a solid, level base which matches or exceeds the building’s footprint in size. Not only does this save you money in the long term by extending the life of your garden room, but it also provides protection against damaging elements like insects and ground water. Additionally, for convenient access and future maintenance, ensure you leave at least 60cm of free space around the building, free from any obstructions. This clearance allows for smooth construction and makes it easier to navigate around the structure during future maintenance.

For those skilled in DIY, our range of DIY garden rooms are an excellent choice! These buildings are supplied with in-depth, comprehensive instructions and step-by-step videos to assist in the construction. Prefer a hassle-free installation? Our other garden room ranges come with home installation as standard. Our expert installers ensure your garden room is constructed to the highest standards, taking care of every detail. Plus, they’ll tidy up any leftover debris, leaving you to enjoy your brand new garden room in peace!


9. Installing utilities

Whatever your garden room’s purpose, it may be beneficial to install facilities such as electric power, water, or drainage. These additions boost the building’s versatility, making it perfect for a home office, personal gym or entertaining space. Ensure that these facilities are installed by qualified, competent tradespeople, and always check with building regulations and your local planning office before beginning work.

Electricity

For safety and building regulations, it is essential to have a qualified electrician handle the electricity installation for your garden room. You can prepare for the process by digging necessary trenches to lead the cables and marking out the proposed route. Connecting electricity to your garden room opens up a multitude of opportunities to reinvent your space. Additions such as lighting and plug sockets are essential for a functional home office or entertainment space, and offer versatility for future renovations.

Internet

Uninterrupted internet connectivity is a must for remote workers or business owners working from their garden room. There are a few ways to connect the internet to your garden building, considering your garden and home setup. Explore options like extending your home WiFi connection to reach your garden room, either directly or with the help of a signal booster. Keep in mind that insulation and double glazing may impact the signal strength from your house. For a more reliable connection, another option is to run an ethernet cable alongside your electric supply. This ensures a stable and consistent internet connection for seamless work and productivity.

Water

Prevent leaks and potential damage in your garden room by enlisting a qualified plumber to install water pipes. You can prepare for the task by digging the trench yourself, just make sure to consult a plumber first for guidance. Ensure the safety of your water supply by maintaining a minimum distance of 350mm from other pipes and wires. Make sure to locate existing services beforehand to avoid any conflicts. Additionally, water pipes should be installed below the frost line, which means a minimum depth of 750mm. Line the bottom of the trench with builder’s sand to provide a soft base for the pipes and cover up any sharp stones that may cause damage.

Drains

The easiest and most permanent drainage solution is to make a connection to your house’s mains drainage system. This is the best option if you are installing water or a bathroom in your garden room. However, if your building is located below the level of existing drains, you will need a domestic pumping station which requires a power supply.


10. Maintenance

Regular maintenance is essential to ensure your garden room remains functional and in good condition. Mercia’s insulated garden rooms are supplied with a 10 year anti-rot guarantee, providing it is treated with a wood preservative and waterproofing topcoat after installation and annually thereafter. To maintain the building between treatments, it is recommended to regularly clear any debris away from the building and check for damp or mould. Efficient maintenance of your garden room will ensure its longevity and functionality, so it can be utilised and enjoyed for years to come.
