    Check out our BillyOh Harper range. The apex summerhouse is designed with tongue and groove (T&G) panels, with a Georgian bar window giving the Harper a long established, traditional look.

    Available in a range of different sizes, the Harper can fit in all types of garden styles and sizes. Our smaller buildings are perfect for gardens with less space or couples who need a cosy room for themselves (4x6 to 8x8). We also have larger designs (10x6 to 12x8) available, which are great for bigger families who want a place to host guests.

    Get Cosy In Your Garden

    The Harper style offers a cosy space with a traditional look, where you can get some quiet, peace and relax. Go outside get yourself comfy and enjoy the feel of your summerhouse.

    The lower roof panels and shelf space on the wall give the summerhouse a snug and intimate aura, making it an ideal area for winding down after a tough day.

    The 11mm T&G floor option is recommended as a popular option and would really compliment the T&G panels.

    We use our 11mm Tongue and Groove fittings for the Harper summerhouse. The T&G fitting offers an authentic look, whilst also offering great protection against the British climate. So there is no need for concern when it comes to storing away furniture.

    The panels are pre-made on site by our UK workforce using traditional methods. The boards are cut to length, with the panels interlocking together to give the construction it’s strength, not allowing water entry.

    Georgian Bar Door and Windows

    With the Harper, it doesn’t matter if you are next to two fences, or need to fit into a corner space. You can enjoy looking onwards towards the rest of your garden with the Georgian bar doors and window design.

    The classic Georgian style door and windows make this summerhouse a traditional, authentic looking unit. They are glazed using 1.2mm styrene for the windows and 1.8mm styrene for the doors.

    Alternatively, if you do have limited space or want to go with a more modern look, you can custom fit the windows to suit you. We offer a variation on the design of the windows and doors, to keep the Harper at great value for money.

    If you love the feel of a comfortable, cushy summerhouse and want to keep your garden style up to date, the Harper is ideal. By changing the window and door style you can combine traditional and modern keeping to a more contemporary garden style.

    Fits Through a Standard Door

    With our BillyOh designs we want to make construction and delivery as easy as possible. All of our panels are made with the intention of fitting through your front or back door.

    Sometimes gaining access to your garden and moving large panels through can be difficult. So we want to do the hard work for you.
