The BillyOh Petra summerhouse range has been designed to offer a modern and contemporary look to a popular style of summerhouse. The combination of the T&G boards, long windows and glazed door achieve this at an affordable price.

We offer this building in our 8’ and 10’ gable sizes in different configurations so all garden sizes and types, whether you are looking for a small hideaway (10x8) or a large space to relax (20x10) we have a size for you..

Each wood board is soaked in treatment until it is absorbed then dried. This protects the wood inside-out which is better than regular treatment spraying or using rollers which only coats the surface of the wood.

The pressure treatment penetrates the wood leaving you with a building that is low maintenance and doesn’t need treatment at home. You will save money in the long run and free yourself of maintenance worries.

All of our non-PT buildings come factory finished for transit, requiring treatment after installation and regular maintenance to maintain quality. We have a variety of paint and primer products available as additional extras. Note: all paint comes in a tin, not pre-painted onto the panels.

Create a place to relax at the end of the garden with this modern, stylish and versatile summerhouse design. The long windows and door allow you to appreciate views of your garden and entertain in all weathers.

Long windows and high apex roofline are features designed to give the Petra Summerhouse a light and airy interior, whether stood up or sat in comfort.

Built using Tongue & Groove panels, the Petra has a secure and stable structure which is built to last. The panels interlock, creating a smooth finish which enhances the style of the summerhouse. The interlocking Tongue and Grooves form strong panels which create a strong structural strength.

All of our buildings are Spray Treated for transit, but we recommend treating the wood after installation to protect it. Paints are available in a variety of colours, so you can protect your building whilst decorating it in a way which looks great in your garden. Note; Paint is supplied in a tin for application, not pre painted.

In addition to the T&G engineering, you can take the protection and maintenance of your building up a notch by going for the Pressure Treatment option which infuses each wood with treatment. This increases the longevity of the building and frees your maintenance worries.

Modern styled doors and windows are a key feature in the Petra Summerhouse Range Summerhouse. With the large windows, you can allow lots of natural light into the building, and you can relax in comfort whilst admiring your garden space all year round.

The doors are constructed from pre planed timbers rebated for an easy to fit glazing system. These are fitted together using pre machined Mortise and Tenon joints providing a solid construction at a great price. The glazing used is a 1.8mm styrene providing a simple, effective and safe solution.

The long windows are glazed using the same 1.8mm styrene as the door. These are simply fitted into the rebated area and held in place with beading.

You can choose where you put the doors and windows along the front. The frontages of the buildings can be set to offset or central, to suit how you want to use the buildings. With this versatile feature, you can personalise your Summerhouse to exactly what you want and need to fit your garden.

Central door positions are great when positioned in the centre of the garden with space either side. Advisable for summer houses where you enter into the centre of the building, typically with all seating focused on the centre of the room.

Offsets buildings suits the building to be situated near an existing path or corner. The side windows can be placed either side to suit.

The images in picture show an example of a 10x8 with central doors and 20x10 with offset door.

All of the panels and sections used in the BillyOh Petra Summerhouse fit through a standard door opening. What this means is that you don't require rear access to get this model installed in your garden. Simply walk the easy to manage panels through your home with ease.

This panel construction method makes these easier to handle and lighter to carry.

Choose from a range of floor options. OSB offers a value floor for the shed, while the Durelis Solid Sheet provides a water resistant, standard level of protection. These floors are suited to lighter items being placed in the storage unit.

The 11mm T&G provides a stronger, interlocking floor for the shed. For larger and heavier items, we recommend, our premium flooring options which are the 19mm T&G floor and the pressure treated 19mm T&G floor.

If you’re looking for a floor which is durable and well protected, pressure treatment is a great choice. This floor option provides unmatched strength and durability. It also means no treatment is required at home.

The Petra Summerhouse comes with a durable 11mm panel Tongue & Groove roof. The roof is extremely strong, built using the same techniques as the rest of the building, and will protect your summerhouse from harsh weather and falling debris.

Petra Summerhouses come with Sand Felt for basic roof covering protection. You can upgrade your roof cover to Mineral Felt to add extra protection against elements. Mineral felt is watertight and provides a waterproof covering to your roof and building. The felt is longer lasting than basic sand felt so will not require replacement as frequently.
