Buying Guide - Summerhouses

A summerhouse adds a captivating centrepiece to your garden and offers a comfortable, sheltered space for you to work, relax, or entertain while enjoying scenic views of your garden. With an extensive range of styles and designs to choose from, it can be challenging to find the summerhouse that meets your needs and requirements. Our comprehensive buying guide will offer insights into common uses, sizes, shapes, and styles of summerhouses to help you find the perfect one for you.

1. How will you use your summerhouse?


Escape the chaos of daily life without the hassle of commuting by transforming a summerhouse into your own private office or workspace. This affordable option often appeals to creative professionals, including artists, writers, and potters, as the spacious interior and abundance of natural light serves as an inspiring workspace. If you require Wi-Fi connectivity or running water in your summerhouse, there are several approaches to installing these utilities. The best method for you will vary based on the layout and positioning of your home and garden.


Ideal for creating your very own peaceful garden retreat, summerhouses offer shelter and comfort to enjoy scenic views of your garden. No matter the weather, summerhouses offer warmth and a peaceful respite from the hustle and bustle of daily life. Their natural timber construction allows for effortless personalisation, ensuring you can tailor your retreat to reflect your unique style. A lick of paint, a few key pieces of furniture and those all-important finishing touches are all it takes to bring your dream relaxation zone to life.


Perfect for the warmer months, a summerhouse is an ideal space to entertain friends and family. Whether you’re looking to host a unique dining experience, need extra shelter for barbecue guests, or require a quiet location for a cosy movie night, Mercia has a summerhouse for all occasions. Plus, if you’re an expert party host, our range of garden bars are a showstopping addition to any outdoor space. Available with shutters to allow for storage, these versatile structures will become the hub of every party.

2. Size and placement

When choosing the size of your new summerhouse, consider how it may be used in the future. Is there a possibility you might need more space down the line? If budget and garden space allow, buy a slightly bigger summerhouse than the one you think you need to allow for adaptability in the future. Please note that planning guidelines restrict any garden building from occupying at least 50% of your garden without planning permission. Most commercially available summerhouses are designed to fall within mandatory planning restrictions, but it is advised to check with your local planning office before making any purchases.

It’s also important to assess your installation site. To utilise the building to its full potential you may want to observe where the sunlight hits your garden throughout the day and position the summerhouse according to your preference. Before construction you should ensure that at least three feet of space will be left around the building to allow easy access during the install and future maintenance. Planning to add utilities such as electricity or running water? Take into account the summerhouse’s proximity to any vital infrastructure you need to avoid any unnecessary headaches.

Once you’ve chosen your summerhouse it’s time to make a base! The base of your summerhouse must be solid and level to protect the building from water build-up which would lead to rot and degradation. A good base will save you money in the long run as it extends the life of your garden building and helps to keep it away from elements which cause damage such as insects and ground water.

3. Summerhouse styles

Mercia summerhouses are available in a variety of stylish and eye-catching designs. The overall look and character of a summerhouse is strongly influenced by its roof shape, and door and window design. Features such as Georgian style windows or bi-folding doors may determine the building’s usability and affect how it integrates into your garden’s style.

6. Maintenance

Regardless of the type of treatment your building has received, it is important to note that regular maintenance is necessary to ensure your summerhouse’s longevity and functionality. Maintain the building by regularly clearing debris and checking for damp and mould. All buildings are dip treated before leaving the factory to protect the building while in storage and transit.
