Flex Pent Security Shed

A secure, modular pent shed you can configure to suit your garden.

Why choose a Flex Pent Security Shed?

If you need a shed that puts security first, most standard garden buildings fall short. Weak doors, poor locks, or awkward layouts can leave tools and equipment exposed.

The Flex Pent Security Shed is built to solve that. It combines solid timber construction with reinforced locking and narrow security windows, all wrapped up in a flexible, modular design that adapts to your space.

How does the modular design work?

The Flex Pent range uses interchangeable wall panels. This means you can choose exactly where the doors and windows are positioned, rather than being forced into a fixed layout.

This makes it much easier to fit the shed against fences, walls, or into tight corners while still keeping access practical and secure.

What makes this shed more secure?

Every Flex Pent Security model is designed with protection in mind. Windows are kept narrow and glazed with 3mm toughened glass, helping reduce vulnerability.

Doors are full boarded tongue & groove timber and fitted with security bars, padlocks, and lock & key systems. Double door versions include a hasp and padlock setup for extra peace of mind.

Is the construction solid?

Yes. The shed uses 12mm shiplap tongue & groove cladding all round, supported by a strong 28mm x 44mm timber frame.

The roof and floor are also 12mm tongue & groove boards, giving the building a sturdy feel underfoot and helping it stand up well to everyday use.

What about the roof and weather protection?

The pent roof gives a clean, modern look and can be sloped front to back or back to front, depending on how you want rainwater to run.

It’s finished with grey mineral felt and supplied with a temporary water-based treatment. For best results, the shed should be treated inside and out after assembly and then re-treated annually.
