Correct, feel free to explore the versatility of the Porto Log Cabin. Decide to place your veranda on the left or right side of your cabin, so you can build the Porto to suit your garden space.

You can even place the single door on either side of the Porto Log Cabin, so you can either have a private and secluded veranda, or opt for the popular veranda with single door entryway, the choice is yours.

Untreated: Our log boards can be delivered to you as untreated allowing you to enjoy the rustic and traditional aesthetic of a log cabin. Not only does this provide you with a lodge appearance, but allows you to decide the treatment type and colour which suits your tastes.

Pressure Treated: For a more protected building, you can opt for a pressure treated building which is an effective way of keeping the building long lasting. This is an extra step in the construction 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 termite.

We offer a range of roofing and flooring options, so depending on how you’re going to use your log cabin, you can choose the better option for you.


11mm T&G: 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 more premium look and feel

19mm: Heavy-duty and long-lasting, this roof will provide you with extra insulation for those colder months of the year.


11mm: Our standard flooring option which provides a durable and provides a 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, economic 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.

The double door is: 1870mm x 1548mm

The single door is: 1870mm x 774mm

Single Glazing: Crafted from shatter-resistant plastic (SAN) and suitable for seasonal use. SAN is used for its UV properties and the tougher finish avoids breakages, when compared to the properties of glass shattering. Single glazing is the perfect choice for seasonal buildings such as summerhouses and sheds providing plenty of natural light into the building.

Double Glazing: Created from toughened glass, the double glazing is the ideal option for a building which is used all year round. The extra thickness will provide better insulation and keep your building warmer in those colder months of the year.

If the building is shorter than 2.5m tall you should not require planning permission, (unless it’s more than 50% of your garden or to be put in your front garden). Planning permission rules can vary by area so we would strongly recommend checking your local council rules before ordering from us.

Using the assembly instruction included and with a team of just 2 people and a bit of DIY knowledge you can expect to have your BillyOh building up within a day, or as little as 3-4 hours with some of our smaller buildings.
