Classic A-frame design with central ridge, providing maximum headroom and excellent water runoff
The apex shed is the most recognisable garden shed design, featuring a classic A-frame roof with a central ridge. This traditional style has been the go-to choice for British gardens for over a century, and for good reason.
The defining characteristic of an apex shed is its symmetrical pitched roof, which slopes down equally on both sides from a central ridge. This design provides maximum headroom in the centre of the shed and excellent rainwater runoff.
The apex design evolved from agricultural outbuildings and has become the standard against which other shed styles are measured. Its popularity stems from its practical balance of space efficiency, structural simplicity, and pleasing aesthetics.
Choose an apex shed when you need:
Apex sheds are the default choice when you have no specific constraints. They work in almost any garden setting and provide the most versatile internal space.
Choose the right size apex shed for your needs:
| Use Case | Recommended Size | Floor Area |
|---|---|---|
| Basic garden tools | 1800mm x 1200mm | 2.16 m² |
| Mower and tools | 2400mm x 1800mm | 4.32 m² |
| Bikes and equipment | 3000mm x 2400mm | 7.20 m² |
| Multi-purpose storage | 3600mm x 2400mm | 8.64 m² |
Apex sheds work well on either concrete bases or bearer/joist systems. For larger sheds (over 8x6ft), consider concrete for long-term stability.
The apex design requires careful rafter cutting with matching angles. Creating a template rafter and using it to mark all others ensures consistency.
The dual-slope roof can use any covering type. Felt is most common, but EPDM or metal sheets suit larger sheds. Ensure adequate overhang for weather protection.
Consider adding collar ties between rafters if the span exceeds 2.4m. These prevent the walls from spreading under roof load.
2.4m x 1.8m
The most popular size for typical British gardens. Fits a lawn mower, garden tools, and seasonal items with room to spare. Includes a single door and one window.
3.0m x 2.4m
Larger footprint for families with bikes, garden furniture, and outdoor toys. The extra depth allows for organised zones within the shed.
In most cases, garden sheds are permitted development and don't require planning permission. However, restrictions apply: the shed must be single storey with maximum eaves height of 2.5m, maximum overall height of 4m (for dual-pitched roofs) or 3m (for any other roof), and must not cover more than 50% of the curtilage. Sheds must not be forward of the principal elevation. Listed buildings and conservation areas have additional restrictions. Always check with your local planning authority if in doubt.
Options include concrete slabs, paving slabs, pressure-treated bearer and joist systems, or adjustable post supports. Concrete provides the most stable base for larger sheds, while bearer systems are quick to install and allow airflow beneath the floor. The key requirements are: level, stable, and dry with adequate drainage around the perimeter.
A well-built and maintained shed can last 15-25+ years. Key factors are: quality of original construction, adequacy of foundations, quality of timber treatment, regular maintenance (retreating cladding, checking for rot), and roof condition. Budget sheds with minimal maintenance may only last 5-10 years.
Ideally, treat all surfaces before assembly - this ensures hidden faces are protected. Pay special attention to cut ends, which are most vulnerable to moisture. After construction, apply treatment to all accessible exterior surfaces annually or as the product recommends.
Apex sheds provide maximum headroom at the centre, work better for taller storage, and have a traditional appearance. Pent sheds are better when height is restricted or when positioning against a fence. For most general-purpose uses, apex is the default choice.
