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.

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.

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.

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.

More About the Expert Corner Shed Workshop...

The Expert corner is a fantastic affordable solution for conserving space in your garden while still offering a convenient solution to storage. The 7x7 shed fits into the corner of your garden and comes in windowed or windowless variants. With a compact design made for any garden space, and able to store anything from garden equipment to outdoor furniture, this corner shed is the perfect solution for an awkward or small garden.

The windowless version provides increased privacy and security - ideal for secure storage such as bike storage, BBQ storage, or a garden tool shed. In contrast, the windowed option offers natural light, lending itself to a small home studio or workshop. 

Tongue & Groove Floor and Roof

The Expert Pent comes with 11mm tongue and groove flooring and roof as well as green mineral felt. The robust groove floor and roof and floor give this corner shed a solid and durable construction, and a sturdy underfoot feel. To increase your sheds vertical storage capabilities further, you can even add on shelving. This is a great way to make the most of your wall space and building height without losing out on floor space.

This garden storage shed is versatile and compact, giving you a great storage solution without removing lots of floor space from your garden. Many of our customers have customised their sheds with shelving, workbenches or by simply painting them. For inspiration on how you can make the expert pent suit your space and your needs see the images below.

Tongue and Groove Garden Storage Solution

Tongue and groove timbers interlock together to provide a tight seal against water ingress. This cladding style is used in the groove walls, floor, and roof of this BillyOh Expert corner workshop. Quality tongue and groove panels also help with insulation and thermal regulation - keeping your builder warmer in cold weather and cooler in hot weather - perfect for a workshop.

Wide-opening Double Doors

And with the option for windowless security shed or a 7x7 model with windows, you can customise your preferred style. Wide-opening double doors for ease are featured on windowed and windowless options to make frequent usage easier in your ideal workspace. Galvanised steel ironmongery is also used for hinges and fixings for security and your peace of mind when purchasing this versatile building.

Installation and Assembly

We don't offer installation services as our BillyOh buildings are designed to be easily put together with just a few hours, some basic tools, and a pair of helping hands. Follow the installation instructions provided with your order to erect the Expert workshop on a level base like pavers, timber bearers, an Ecobase (available at checkout), or a concrete base.

Quality and Guarantee

Wood stain and protector paint are available upon purchase to prolong the dependable quality of BillyOh products. The Expert workshop will come with golden brown spray treatment to cover it until after delivery. However, to further protect your building against rot, decay, and insect infestation, we suggest you treat the wood after installation.

Our tongue and groove sheds do come with a 10-year guarantee against rot, however, as a sign of our confidence in our products' quality weather protection.
