Mini Keeper Overlap Apex Bike Shed

If you need an outdoor building to make the most of your outdoor spaces, but garden sheds take up too much room, then the Mini Keeper is the perfect option.

Bike Storage

Get secure storage when you buy a BillyOh bike storage unit thanks to quality materials and construction and security-friendly features like lockable doors.

Cladding Types - Weather Resistant Overlap

The overlap cladding style used in the Mini Keeper means we can offer you a weather-resistant garden storage unit that's built to cope with British weather at a budget-friendly price. With quality weather protection and construction, you'll have a garden building that's bound to last for a long time to come.

Tongue and Groove Floor

And with the 11mm standard and 19mm optional cladding thickness for the tongue & groove floor, you can ensure protection from damp and rot as the point that comes into most contact with moisture. Tongue and groove cladding offers a tight seal against moisture ingress.

Roof Styles - Apex Roof Design

The apex roofline of this garden building isn't just a stylish traditional addition. It's also designed to allow for excellent runoff in even harsh weather - protecting your bikes. And, with a Durelis solid sheet included, you can add to the weatherproof qualities of this overlap bike store.

Double Doors

Double doors allow or both easy access when putting bikes in or taking them out as well as extra security as they support a hasp and heavy-duty lock (available as add-ons upon purchase).

Installation Service and Assembly

Your Mini Keeper will come as pre-assembled panels with comprehensive assembly instructions. That's why we don't offer an installation service - we've made it easy enough for you and a friend to do with some basic tools in just a matter of hours! Just remember to construct your bike shed onto a level base.

You should be able to construct this bike store without planning permission due to the eaves height and ridge height falling well within 'permitted development' (so long as you don't build it past the front wall of your house). However, we suggest checking your local council's planning permission rules if you have any queries.


Your Mini Keeper will come with golden brown spray treatment for dependable quality and protection until it's delivered. Then, we advise that you treat wood after installation. Why not purchase the wood stain and protector paint we offer as add-ons?

Garden Buildings Direct - Delivery

At Garden Buildings Direct, our fast and free delivery service to most of mainland UK means we can get your BillyOh building to you in as little as 1 - 4 weeks. Just enter your delivery address to get started with purchasing your bike store today!

Frequently Asked Questions

Below you'll find answers to the questions we get asked the most about our products.

Spray Treated: Our sheds and summerhouses get a beautiful golden brown spray treatment before leaving the factory in order to preserve the quality of the wood up until the delivery. As this only lasts through the transit stage, we do advise treating the wood after installation to protect and preserve it, as well as annual maintenance.

We offer a range of roofing and flooring options, so depending on how you’re going to use your shed, you can choose the better option for you.


OSB solid sheet is standard on the 3x6 and Durellis is standard on the 3x8.

Durellis & OSB Solid Sheet: A value, cost effective roof option.

Floor: All floor types aren't available on all sizes

OSB Solid Sheet and Durellis Solid Sheet: Both value, cost-effective options for flooring. These floors are suited to lighter items and light domestic use.

11mm: Our Standard flooring option provides a durable, solid foundation and underfoot to the building. The 11mm option is ideal for less demanding and frequent usage, suitable for lighter intensity purposes like summer houses and other living spaces containing light furniture. The 11mm tongue and groove timber makes this a solid yet suitable, economical option.

19mm: A premium floor is the perfect choice for higher intensity usage. The construction uses thick 19mm tongue and groove timber, which gives you not only strength but better insulation against the cold weather. This specific floor is the perfect option if you’re planning on using the building as an everyday use office, gym or games room with heavy objects.

Yes, all garden buildings should be assembled on a firm and level base. A base will ensure your building has a solid, long-lasting and well-drained foundation.

Our robust and simple to use EcoBase provides you with a firm, long-lasting foundation with suitable drainage for your garden building. It is quick and easy to install through the use of snap connectors that link the grids to each other.

If your building is shorter than 2.5m you should not require planning permission, (unless it’s more than 50% of your garden or will be placed in your front garden). Planning permission rules can vary by area so we would strongly recommend checking your local council rules before purchasing a garden building from us.

We do not offer an installation service on any of our buildings, as they are designed to be easy and simple to assemble. Using the digital assembly instructions included in your order confirmation and with a team of at least 2 people, the handy pre assembled panels mean you will have your BillyOh building up in no time!

Our sheds and summerhouse are delivered in easy to assemble panels. For your convenience the panels are no wider than 4ft so they can be easily maneuverable and fit through a standard doorway. Glazing and any additional wood is delivered in separate, clearly labeled packages.

Your order can be tracked through the account section on our website or by contacting us directly. You will be contacted after your order via your online account, email or text to provide updates on delivery dates.
