A guide to choosing the perfect shed

How to choose the best garden shedForest Gardens logo

Sheds are one of those versatile staples of the British back garden, but there are now more options than ever if you’re looking to get a shed or garden workshop project off the ground. A shed can be purely practical or a neat little talking point – it all depends on what it’s going to be used for and how much space there is to play with.

Take a look at this Forest shed selector below, making choosing a shed a breeze.

The five step guide to choosing a shed

1. Choose a size

4x34x3, 5x3 or 6x3 – small and compact. Perfect for neatly storing garden tools or bikes but it will be a squeeze if you need to store larger items


8x66x4, 7x5, 7x7, 8x6 or 8x8 – the mid-size choice. Suitable for larger equipment like lawnmowers and bikes


10x810x6, 10x8, 10x10, 12x8, 15x10, 20x10 – large and spacious. Offers more storage space or big enough to be used as a workshop

2. Choose a style


Apex – Useful if the shed will be used to store tall items. Water will run off easily when it rains

– A good choice if height needs to be restricted for any reason. Guttering that leads to a water butt can be added too


Reverse apex
Reverse apex
– Similar to an apex style but the door is on the longer side of the shed, another option to consider depending on the space available


– If a shed will be placed into a corner this style makes sense. Can also be used to hide an area of a back garden

3. Choose the construction

Overlap icon Overlap – Rough-sawn boards overlap to ensure water run-off

Shiplap tongue and groove Shiplap tongue and groove – A more robust set up with interlocking tongue and groove boards with a shiplap profile for water run-off

Tongue and groove icon Tongue and groove – Very tough. Tight tongue and groove boards for wind and rain protection

4. Choose the treatment

Forest offers two types of treatment:

  • Dip treated – the shed boards are dipped in anti-fungal solution at the factory. A surface-level treatment that provides short term protection against rot. 10-year anti-rot guarantee provided
  • Pressure treated – anti-fungal preservative is forced into the timber under pressure. 15-year anti-rot guarantee provided

5. Prepare the base

Forest recommends a base for the new shed is prepared one of three ways:

Concrete slabs
Concrete slabs – these are laid neatly with minimal gaps, on top of a dressing of sharp sand and hardcore


Concrete – a solid concrete base will minimise movement of sub-soil, so there’s much less chance your shed will move or drop over time


Timber base
Timber base
– this would be made of a timber frame that’s attached to stakes driven into the ground. Can be a useful solution if concrete or concrete slabs can’t be used

Features to look out for

  • PET glazing - Shatterproof plastic glazed windows can be fitted on either side of a shed
  • Felted roof – A weatherproof felted roof constructed from durable sheet material is robust
  • Solid floor – A pressure treated solid timber boarded floor will outlast other types 
  • Finial and barge boards -  A nice finishing touch
  • Strong construction – increased framing and a metal roof truss bracket will boost strength
  • Hidden hinges – these can’t be unscrewed from the outside so are an added security feature
  • Latch security – a shed door can be secured and locked with a plate hasp and staple latch
  • Robust doors – double ‘z’ framing will prevent doors from dropping over time
