Overview

A pent shed features a single-slope (mono-pitch) roof that angles from front to back. This streamlined design makes pent sheds ideal for positioning against walls, fences, or in locations where maximum height at the front is desirable.

Key Features

The key advantage of the pent design is its lower rear height, allowing it to fit under eaves, against boundary fences, or in situations where planning restrictions limit maximum height. The sloping roof still provides adequate water runoff.

History & Design

Pent sheds gained popularity as gardens became smaller and the need for space-efficient storage solutions increased. They maximise usable space while respecting boundary constraints.

When to Choose a Pent Shed

Choose a pent shed when you need:

To position the shed against a boundary fence
A lower overall height for planning compliance
The shed to fit under existing eaves or trees
Maximum frontage height with a lower rear
Simple roof construction with single-direction runoff

Pent sheds excel in restricted spaces and where height limits apply. The asymmetric design can be oriented to direct rainwater away from boundaries or paths.

Pros and Cons

Advantages

Lower overall height
Simple roof construction
Easy to position against fences/walls
Modern, clean appearance
Rainwater directs to one side only

Considerations

Less headroom at rear
Limited internal height variation
Can't add loft storage
Asymmetric appearance not to all tastes

Construction Notes

Foundation

Pent sheds can often sit on simple pressure-treated bearers, as the lighter roof structure creates less load. Ensure the slope direction matches your drainage needs.

Framing

The graduated stud lengths on side walls require careful calculation. Cut one set as a template and use consistent stud spacing.

Roofing

Minimum pitch of 10° for felt, 5° for EPDM. Ensure roof sheets or felt extend adequately at the low edge to prevent wind-driven rain entry.

Special Considerations

If positioning against a fence, leave 50mm gap for air circulation and maintenance access. Check boundary regulations before building to the fence line.

Frequently Asked Questions

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.
