Kit delivery is generally between 5-6 weeks from ordering.
The entire kit can be delivered to your site by truck or it can be picked up from our warehouse.
This depends upon the amount of labour and skill level. As a guide, a non-skilled owner builder can erect frames and roof trusses for an average size home in 2-3 days then the remainder of the build is similar to that of normal build times.
A smaller kit can be built to lock up in roughly 7-8 days. Larger, more complex granny flats will take longer. You should allow 10-12 weeks on site for an average granny flat to be fully constructed.
Design, Costing and Inclusions
The kit includes all materials required for lockup but does not include on-site labour, site survey, site costs, PC items, Concrete, Electrical and plumbing etc.
A full list of inclusions, exclusions and optional extras are detailed on each of our designs.
As an owner builder/manager you are effectively cutting out the builder and therefore should make a saving of 20% to 30%. If you choose to be more hands on and undertake some of the manual tasks such as erecting the walls and roof trusses, installing windows, doors and painting the internals, your savings will be increased further.
Yes. Kits can be upgraded to a cyclonic rating at an additional cost. These kits are manufactured with extra reinforcements that will make them suitable for areas prone to cyclones.All standard kits can be upgraded to cyclonic kits.
