The Haven Cabin Kit 20m²

The ‘Haven’ cabin kit is definitely our most popular designed cabin as it lends itself to a multitude of uses.

Some of our clients use this cabin kit as a home office with a basic toilet configuration while others have used it as an art studio and used the bathroom space just for storage. The ‘Haven’ is also great as a teenage retreat as there is enough room for a kitchenette and a queen size bed as well as a toilet, shower and vanity in the spare room space that comes with this model as shown in below left side diagrams. The “Haven” kit suits being a ‘Mancave’ or ‘She Shed’, overnight accommodation, music room, yoga or gym, swimming ‘pool house’ or just the space you need to get away from it all in the convenience of your backyard. It comes with Tongue and Groove Timber floors, Double Glazed Windows and a 1.5 x 5 metre covered verandah.

This cabin comes as a kit only which includes the colourbond roofing in a colour of your choice and standard base kit with bearers, joists, standard roof batons and 125mm round treated pine poles. Kitchen, bathroom, electrical, plumbing and roofing insulation are not included.  

NSW council regulations now allow cabins up to and including 20m² in your back yard without council approval. Conditions apply. Click here to see legislation

Usage Ideas for your Timber Cabin

This size is common to be used as a home office for one 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 comprehensive 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 listed above.
But, Sub Floor Base kits can vary in price due to your site specifications. Certain 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.
Sloping blocks also make a difference to the lengths of posts both in and out of the ground which leads to more expensive posts and concrete.
We provide the sub floor kit based on a standard flat level ground site.
We are here to help. We can guide you through what’s required for your site as part of our discussions if you decide to proceed with a cabin purchase.

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. 

DIY - Handy Info

If you have had reasonable experience in DIY projects, then our cabin kits are very straight forward and easy to assemble. If your kit does require council approval then you can DIY as a licensed ‘Owner Builder’ or enlist the help of a licenced, local Carpenter or Builder.
Sometimes it is a better use of your valuable time and more cost effective to have our installation team come and install it for you. Prices for installation are located on this page.  This cabin takes about 1 week onsite for our installers to complete the cabin build to lock-up stage.


Cabin Kit delivery cost depends on several factors. Geographic location, type of cabin kit, access for the crane truck. If you cant wait for a cabin and want it now, check out our ‘In-Stock’ cabins page on this website
