The bathroom has high quality fixtures and fittings. These include a shower, dual flush toilet, heated towel rail, mirror and sink with cabinet & draws. The bathroom also includes a stainless steel mains pressure water heater and a laundry area.

The Onesie is designed with privacy in mind with doors between living spaces and windows on one side of the building – keeping the neighbours out of sight.

The queen bedroom is large enough for side tables, wardrobe and chest of draws.

The Onesie is built in our factory and transported in separate modules to your site. Building in our factory ensures a dry and controlled environment that ensures a high level of quality is maintained.

After a building consent is issued, it is a quick build time of between 4-6 weeks to complete your home compared to the industry average of 25 weeks. This saves you time and money.

The modules are made from New Zealand timber to the New Zealand Building Code NZS3604. Engineered for strength, the frames are designed to work with the steel jointing system between the floors and walls.

The houses are almost all completed in the factory with final assembly, waterproofing and landscaping completed on site.
