Envirotech N.Z.

Domestic Design Services specialises in designing and building modular buildings using a sandwich panel of coloursteel and expanded polystyrene (BONDOR).These units meet the new insulation standards, even in the harshest climates.

We have a range of standard units, or can design specifically for your needs.

They are built in a factory or on-site, and in most cases are transported to your site fully completed with floor coverings, cabinets, plumbing fittings, all lights & power points with an Electrical Certificate, all ready for hooking up to your services.

We specialise in providing stand-alone unserviced units generating your own electricity using a combination of solar and wind power, which is being developed all the time.
