BillyOh Petra 12x10 Reverse Apex Summer House – Log Cabin

The BillyOh Petra is a generously sized 12x10 garden room that works equally well as a home office, hobby space, gym, or simply a peaceful retreat at the end of the garden. Its reverse apex roof gives it a distinctly contemporary look that sets it apart from traditional summerhouses, while panoramic windows flood the interior with natural light and keep the space feeling open and airy throughout the day.

Construction is solid throughout, with interlocking tongue and groove panels forming the walls, floor, and roof for a weathertight, stable structure that should stand up well to the British climate year after year. The shatter-resistant SAN glazing offers UV protection and added peace of mind if you have children or grandchildren about, and the mineral-grade roofing felt provides a reliable barrier against wind and rain. Wide double doors make it genuinely practical too — moving in a desk, sofa, or gym equipment is far less of a headache than you might expect.

One of the Petra's more thoughtful features is its adaptable panel design, which lets you reposition the doors and windows to suit your particular plot and get the best from the available light. That flexibility makes it a good fit for gardens where aspect or layout can be a limiting factor. It will need treating with a suitable wood preservative after installation, but maintained properly this is the kind of structure that earns its place in the garden for the long term.
