There are a few considerations needed before purchasing a shed. Some are based on how it will be used, and others are more based on appearance, location, and available space.

Shed Sizes, Bases, and Siting

Most sheds are organised by width, and generally this is measured on the side with the door. Level ground is critical, and you may need a base for additional stability. There are options for plastic interlocking bases or wooden frame bases depending on the kind you need. You can visualise how much space you need by laying a hose pipe down around the area you plan to site your new shed.

Shed Roofs and Styles

An apex roof is two sided with a high ridge in the centre. Pent-roof designs have a single sloped roof with double doors offering greater accessibility. Both types are designed so rain easily runs off the sides, and guttering kits can typically be added for better control if needed.

Security sheds are built without windows, and they offer extra reinforcement in the doors. A corner style is perfect when space is a premium as it can easily fit into a right-hand corner of the garden, saving valuable space. Potting sheds are a combination storage space that adds greenhouse-style windows, designed for potting seeds and planting as well as a normal storage space.

If you are purchasing one of the options with windows, be sure to consider whether glass or styrene is best for you. Styrene is ideal if the building is positioned where glass could be broken, so it’s more ideal if this will be next to a play area. Glazed sheds offer greater security and let in more light, so they are generally preferred.

Shed Materials

Wood offers the greatest choice in shape, style, and function. Pressure-treated timber requires little maintenance, but dip-treated sheds will need repainting within the first two years. Both treatment types can be painted easily to suit preferred colour schemes.

Overlap sheds are the standard value and this cladding is made up of boards that simply overlap one on top of the next. Tongue-and-groove boards are the next step up, and they have special channels that interlock with each other for an almost airtight seal. Shiplap cladding combines the best features from both. They have interlocking or grooved channels for a more secure construction, and there is an additional lip on each panel to assist with rainwater runoff and quicker drying.

Plastic sheds are maintenance free as they arrive prefinished and are quick to build; however, they do need a concrete base in situ before assembly. Metal options have a simple design, always without windows, and offer a high level of security due to the material used. They are great for storing animal feeds as they tend to be anti-vermin.

Assembly or Build Your Own

All sheds are delivered unassembled, but there are options by Forest Garden and Mercia that offer an assembly service. This does not include a ground preparation service, and the assembly team will only be able to work on a prepared level surface.
