Storage

If you're seeking a reliable solution to store your garden equipment and tools, a garden shed is the perfect choice. With a wide range of sizes, shapes, and materials available, you'll find a shed that fits your budget. For smaller items or limited outdoor space, explore options like bike stores and mower stores for efficient garden storage.

Outdoor living

To expand your living space during the warmer months, a summerhouse may be more suited to your needs. These versatile and stylish buildings allow you to enjoy your garden in shelter and comfort. However, if you require a garden building which can be used all year round, then opt for a log cabin or insulated garden room. These buildings benefit from thick log boards and insulated walls respectively, ensuring a cosy environment even in the winter months.

Work and hobbies

Our large wooden sheds and workshops offer ample space for DIY projects, hobbies and home offices. With sizes up to 20ft x 10ft and various material options, you can transform these large buildings into your personal workshop or hobby room. For a year-round home office, consider an insulated garden room or log cabin.

Growing

For storing gardening tools and equipment, a garden shed provides the perfect solution, with options for shelving or storing larger equipment. However, if you require a shelter with the ideal growing conditions for your flowers and plants, explore Mercia’s greenhouses! If you desire both storage space and a sheltered growing area, our combi greenhouses offer the best of both worlds—a secure tool storage space and a spacious area for plant cultivation.


What size shed do you need?

Mercia offer a diverse range of sizes, catering to various needs. From a compact 5ft x 3ft bike store to a spacious 20ft x 10ft workshop, there's a shed to suit every requirement. Unsure about the ideal size? Consider the equipment or tools to be stored and ensure generous space for manoeuvring items in and out of the shed doors. It's crucial to determine the shed's placement inyour garden to avoid selecting a size that is too large. Remember, the dimensions provided are approximate measurements and act as a general starting point. For example, a 5ft x 7ft shed may have precise measurements of 4.8ft x 6.9ft.

Location

When selecting the size of your shed, it is crucial to consider its placement in your garden. Some things you’ll need to consider:

  • The space around your shed; you must leave at least 60cm around your shed for annual maintenance
  • Check you have enough space to open the doors and windows
  • Choose a location with a firm ground to install a strong and level base for your shed to sit upon
  • Avoid placing under trees as falling debris could damage your building

The shape of your shed

When selecting a shed, you'll be pleased to discover the wide range of shapes available, including popular options like apex, reverse apex, and pent. To assist in your decision-making, refer to the descriptions and examples provided in the table below, helping you find your preferred shape. Keep in mind a top tip: while aesthetics play a role, it's essential to consider practical factors such as height, both at the entrance and inside, to accommodate yourself and the items you plan to store. Furthermore, be aware of planning permission regulations, as height restrictions may apply based on your location or the shed's positioning relative to your house.

apex.jpg

APEX

An apex roof features a central peak where two wooden roof sections meet. This classic design is perfect if you plan to work inside your shed, as the roof provides optimum head height.

reverse-apex.jpg

REVERSE APEX

A reverse apex shed features a central high point where the two wooden panels meet. However, the roof runs horizontally from side to side, providing generous headroom and a spacious working area.

pent.jpg

PENT

Featuring a flat single panel sloping from front to back, the pent roof provides sufficient height for the door while aiding in water run-off. This design is perfect for placement near a wall or fence.

barn.jpg

BARN

The barn is the most traditional of all shed shapes. This is a great option to store items which require vertical space, as the barn design supplies considerable internal height.


Choosing the material of your shed

Sheds are traditionally built using wood, as it is an excellent material to manufacture, easy to customise and is visually appealing in gardens. However, there are now various material options available, each with their own advantages and disadvantages. These are broken down in the table below to help you choose the right material for your shed.

Maintenance

Regardless of the type of shed you choose, it is important to note that regular maintenance is necessary to ensure its longevity and functionality. Maintain your shed by regularly clearing debris and checking for damp and mould. If you’re looking for a low-maintenance building we would suggest a plastic or metal shed, as these don’t require any treatment.

Our wooden garden buildings all have a treatment applied before leaving the factory which determines how much maintenance it will need. However, all wooden buildings require a preservative and waterproofing topcoat to be applied once installed and annually thereafter to validate your anti-rot guarantee.

Dip treatment

Our buildings are dip treated during manufacture as standard. This process sees a water-based colourant applied to the timber for protection whilst in storage and transit. However, this is not a preservative, therefore the building requires a preservative and waterproofing topcoat application once installed and annually thereafter. This then validates your 10 year anti-rot guarantee.

Dip-Treatment-1.png

Timber is cut ready for treatment.

Dip-Treatment-2.png

Timber is dipped into a cylinder containing preservative.

Dip-Treatment-3.png

Dip-Treatment-4.png

Pressure treatment

This is a high pressure chemical process designed to preserve exposed timber by providing optimal protection against insect attack, fungal attack and decay. The pressure treatment process drives preservative chemicals deep into the timber fibres. However, pressure treated buildings also require a preservative and waterproofing topcoat application once installed and annually thereafter. This then validates your 15 year anti-rot guarantee.

Pressure-Treatment-1.png

Timber is loaded into a chamber and a vacuum empties timber cells of air.
