11mm Tongue and Groove

Our Standard flooring option which 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 Tongue and Groove

1.7 times thicker than our standard 11mm flooring, our premium floor is the perfect choice for higher intensity usage. The construction uses thick 19mm Tongue and Groove timber, which gives you not only the 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.

Mineral felt

Quick and easy to apply, Mineral felt is durable and protects the building against the elements. The mineral felt is also more durable than traditional sand felt, meaning that it does not need to be regularly replaced, making it a long term, cost effective option.

EPDM Roof Covering

EPDM is a rubber based polymer that is fast and easy to install. It is a great alternative to felt and other roofing solutions, It is resistant to ozone and UV radiation while still being weatherproof and less affected by temperature changes. This option provides a more durable covering for your building while giving a stylish black look to the roof.

BillyOh Expert Reverse Apex Workshop

The Expert Reverse Apex Workshop comes in a wide range of sizes and options suited to an amazing range of uses. The windowed version of the building is perfect for use as a home workshop or just to allow more natural light into the building. In contrast, the windowless option may be your choice due to the increased privacy and security - perfect for storage.

Whatever your choice, both styles come with double doors and ample room to help clear up your outdoor space. Both options use durable 11mm wall, floor and roof construction to create a robust building. The floors can be upgraded further to 19mm thick tongue and groove timber for more intense usage.

Garden Storage

The Expert serves as an excellent storage solution for gardening equipment including bikes lawnmowers and even more valuable equipment, which can be kept safe with a windowless option and latch that will support a heavy-duty padlock.

Wooden Sheds vs Wooden Garden Workshops

With the Expert shed-workshop, you won't have to decide between wooden workshops and garden sheds - you can have it all in one! And you don't have to stop there - a garden workshop can quite easily be converted or repurposed as a garden office.

Reverse Apex Roof

Green mineral roof felt is also included to increase the longevity of your building, helping it last for years to come. And whether you opt for spray treatment or pressure treatment, you can customise your building with a lick of paint. That's why we have a wide variety of hard-wearing shed paint to choose from on our site.

Size and Base

The variety of sizes with this garden storage shed, from 10x8 all the way up to 20x10, allows you to find the perfect fit for all of your needs. The smaller buildings are great for storage, such as for use as a bike store or a garden tool shed, but could also be used as a small garden studio. The larger options lend themselves to wooden garden workshops with more than enough room for storage. With space for a workbench, shed shelves, and the option to have windows, the larger sizes fulfil everything you expect from large garden storage.

We suggested constructing floor joists and your solid timber floor onto a level base like a gravel-filled Ecobase, timber bearers, or even a concrete base. The flooring of the Expert workshop can be upgraded in cladding thickness to support heavier items and even pressure-treated to combat damp.

Cladding type - Tongue & Groove Cladding

The 11mm cladding thickness of the tongue and groove timber walls offer both extra strength and protection from adverse weather conditions. With strong construction that features interlocking panels, the Expert has increased structural integrity as well as a tight seal against water ingress.

Pressure Treatment

And if you don't want to go through the hassle of annual retreatment, you can even have your outdoor building pressure-treated. Pressure treating timber allows chemicals and preservatives to penetrate deeper into the wood whilst in a vacuum, better protecting it for longer.

Exceptional Workmanship

Our skilled craftsmen have pre-measured and cut your timber panels ready for delivery. They'll come spray treated (unless you opt for pressure treatment) to protect them throughout delivery. Simply follow the comprehensive assembly instructions provided with your order to have your Expert up in a matter of hours.

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 in unil 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.

Pressure Treated: For an extra level of protection, you can opt for a pressure treated building which is an effective way of keeping the wood long lasting. This is an extra step in the manufacturing process where the wood is treated in a pressurised tank. Chemical preservatives are forced deep into the wood’s fibres to resist rot, decay and termites. When you upgrade to Pressure Treatment, the guarantee is extended from 10 to 15 years.

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.

If you want to build your own base, from a sturdy material such as concrete or flagstones, you can find minimum dimensions for each size of this building in the tech specs. In order to protect your building from moisture, you should leave a 2ft gap around the exterior of your building, so remember to take this into consideration when laying any sort of base.

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.

With the Expert Reverse Apex an 11mm tongue and groove floor and roof is included but you can upgrade to 19mm to suit more intensive use.

Roof:

11mm: Our standard roof option, this interlocking roof provides a reliable covering for any building. The Tongue and Groove not only gives your building a stronger roof but also a premium look and feel.

Floor:

11mm: Our Standard flooring option which 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 the 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.

The building should be treated once fully assembled and within one month of receiving the product. All the treatments we supply ensure the building will only need to be treated once a year, but always consult the directions on the treatment that you have purchased. Pressure treated buildings don't need to be treated annually but may need to be topped up in its later life.

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 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 by our helpful care team to arrange delivery of your building.
