Protects the wood on your building against rot and decay.
Over 20 years of experience in design and production.
Quicker and easier to build, the Expert Pent is delivered in handy pre-assembled panels
11mm Tongue and Groove roof, floor and green mineral felt roof covering.
Every garden is different, which is why with the Expert Pent Workshop you are in control of the panel placement. Whether you require the door on the left, right or in the centre of the building, you can simply adjust the design by changing the front panels around.
The shed is a solid, interlocking structure made from 11mm Tongue and Groove cladding, constructed using high-quality timber panels that interlock together. Tongue and Groove cladding creates a strong, stable and weatherproof structure with a stylish finish.
Durable Single SAN glazing included as standard. SAN is used for its UV properties and the tougher finish avoids breakages.
The windowless options provide you with maximum privacy, both when you're working and storing items inside. The windowed option offers natural sunlight to the building, a great benefit when you are working inside.
The Expert has been designed to provide you with as much space and mobility as possible. The interior allows you to store lots of items without struggling for space, and the wide-opening double doors make transporting things in and out of the shed extremely easy.
The Expert features generous headroom and high eaves and ridges for added convenience and mobility whilst inside the shed.
Give your building the look it deserves - or simply give it an extra layer of treatment to keep it in great shape. We have a wide range of paint colours and timber treatments available. Simply explore our collection.
Make use of the vertical space afforded by your building with these handy shelving units. Available in two sizes, you can buy as many shelves as you need, with the units themselves specially designed to fit with BillyOh buildings. Use them as a place to keep tools, boxes, toys and more.
Ensure your shed is getting great drainage with our flexible guttering addition. Simple to assemble and with a universal fit to any shed or building with its screw-on design. Comes with a downpipe to effectively channel rainwater.
Give your building the foundation it deserves with the Ecobase. A versatile plastic base, the Ecobase is available in a wide combination of sizes with its connectors to tailor to the building you’ve bought. Made from recycled plastic, you can fill with gravel to allow for natural drainage.
Stay secure with the deluxe padlock and hasp combination. Screws, hasp, shackle, and padlock with key all included. Easy to install and ensures your building is kept safe from intruders. Padlock protector is also available.
The BillyOh guarantee covers this building against:
Please note: The guarantee does not cover timber splits or warping which may occur naturally over time.

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.
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 Pent 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.
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.
We offer a pay by finance option on any purchase over the value of £560.
Our simple finance options allow you to spread the cost of your purchase over 24, 36 or 48 months.Read more about our Pay by Finance option here.
In the BillyOh Expert, we've created an outdoor building that has loads of space, fantastic versatility, and a wide range of optional features and sizes. This ingenious combination offers loads of utility, meaning you can use the Expert for just about anything practical you can imagine - from a storage shed, to an art studio, to a full-blown workshop. The Expert is a truly multipurpose garden building!
This reliable wooden workshop is equipped with 11mm tongue and groove roof and floorboards which ensures a robust structure, as well as a tall pent roof that provides loads of vertical space and great ease of access. Whether you need a shed that can fit all your garden furniture in or a workshop with enough space for your ambitious projects, the BillyOh Expert Workshop fits the bill.
The Expert Workshop is extremely adaptable and features a number of customisable options that you can choose to make your model suit the needs of you and your garden.
We offer the Expert both with and without a set of windows. Choose the windowless option if you want to use your garden building solely for storage, as the lack of windows gives you extra security by hiding your possessions away from sight. You can increase security further by adding a padlock and taking things to the next level with our deluxe padlock protector.
The Expert is also available in a wide range of sizes. Pick the cosy 8x8ft option if you need a small workshop to fit into a tight garden space. If space isn't a problem you can go larger, all the way up to our deluxe 20x8ft workshop and you'll have all the space you'll ever need.
If storage is your priority, you can get some additional space by selecting our shelving option. We'll provide shelving for as much of the shed as you need - from one side to all way around! Or, if you're looking to invest in a little more weather protection for your workshop, you can choose to have it pressure treated.
If you're looking for a dedicated outdoor workshop, the BillyOh expert will be just what you're looking for. With an array of features designed to accommodate workshop elements, the Expert is a popular choice with craftsmen.
The pent roof style gives you loads of vertical space when working inside the workshop. With this extra bit of height, you'll never have to worry about banging your head! The size of the Expert Workshop is also ideal for all the elements that make up a proper workshop, with loads of space for a workbench, tool racks, and all your building materials.
As with all our garden buildings, we offer free delivery to the majority of the UK mainland. Just check whether this applies to you when entering your delivery address on the order screen.
Our delivery is fast and efficient, and we'll keep you updated with everything you need to know up to and including the day of delivery.
Just like our delivery, assembly of your garden workshop is practical and easy. We'll send you a digital assembly manual as soon as you complete your order, meaning you can get acquainted with the instructions before construction even begins!
This BillyOh Building, as with all our tongue and groove models comes with a fantastic 10-year-guarantee. Our guarantee covers your garden building against insect infestation, rot, and even decay of the wood.
If you choose the pressure-treatment option, you'll be glad to hear that the guarantee is extended up to 15 years instead!
