Usage Ideas for your Timber Cabin

This size is common to be used as a home office for 1 or more people. Plenty of room for several desks and a meeting table with a small kitchenette and bathroom.

This is a broad catergory. Visiting relatives from out of town, expanding families needing more room, teenage retreat, divorcee accomodation (it happens), even Air BnB rentals or local traveling workers accomodation. Use for your own needs or rent it out as an income source.

A great space for a pool table, or a big lounge and TV, so you can kick back and enjoy family and friends in a safe, casual and entertaining environment.

Enjoy the ability to potter in your favourite hobbies in your own dedicated space. Art Studio’s, Pottery, Sewing, Beauty Rooms, Massage. It makes a great ‘chill out’ space to read a book, Tutor Music or even Home Schooling. Relax and Recharge with some soft music and a cuppa tea to have a break from the day to day grind. Plenty of clients say their cabin is their favourite “Happy Place” away from the day to day grind.

Nothing beats a dedicated space to work on your favourite hobbies. If your current shed is full of family “items” and doesn’t look like changing anytime soon, enjoy the new dedicated workspace and great size for your gardening passion or computer repairs, or whatever you like doing. Its really up to you.

Building Plans

Easy to Follow Building Plans are included with the cabin kit. We also have a range of instructional videos to help DIY’ers build the cabin step by step.

Sub Floor Base Kits

Our standard base kit is included in the price, But Note: Base kits can vary in price due to site specifications. Cabin heights off the ground can add additional post length. If soil tests are required, some hole diameters and depths may vary and some site specific engineering may be required depending on your cabin usage. We will advise if any variation in price is required, but it is not common that we need to add some to the cabin kit price.

Additional Windows and Doors

Additional Windows and Doors can be added into one of our standard designs. We would advise the price once we have discussed the options available. Adding or removing items from a standard kit may result in a significantly longer delivery time, as the additions or deletions need to be catered for at the factory as a one off build. This can add around 20-25% to the price of a cabin for a one-off design.
