Onesie - 1 bed

A popular design for singles, couples, retirees or as a rental.

The Onesie is equipped with 3 kW solar on the roof that diverts power to your hot water heater system to optimise your household running costs and reduce the carbon footprint.

It includes extra durable, easy-care ply walls and fantastic insulation. Every FirstBuild house comes complete with double-glazed windows and a heat pump to keep you warm in winter or cool in the summer.

The modern kitchen has a ceramic hob, oven and rangehood. The European Inspired kitchen has soft close drawers and a machine stone benchtop. 

You have a great choice of flooring textures and carpet colours.

Each bathroom has high quality fixtures and fittings which 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 site.

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

The Onesie is built in our quality control factory and transported in different modules to the site. 

It is a quick build time of between 4-6 weeks to complete your home compared to the industry average of 25 weeks saving you time and money.

The modules are made from New Zealand timber using the New Zealand Building Code 3604. The frames are extra strong with a steel jointing system between the floors and walls for transport.

The houses are almost all completed in the factory with final assembly, final waterproofing and landscaping completed on site. FirstBuild will provide you updates throughout the build process including when your house will be delivered and craned onto the foundations.
