Building a second dwelling

Second dwellings are popular for generating additional income, hosting guests, and expanding liveable space. If you have a large enough section, a small home or self-contained unit is a clever way to make the most of the extra space and add value to your property.

If you have questions about building a second dwelling, our experienced team is here to help. To ensure you make an informed decision, we have outlined the key things you need to know.

 
 
 

The building process

When building a second dwelling, our prefab houses offer a seamless, cost-effective, and predictable solution. To start with, our team will guide you through consultations, design proposals, sign-offs, colour selections, and consent applications.

Then we begin construction in our specialised factory. Once the basic structure is up, we line the walls and complete the interior fit-out. This includes all the decorating, plumbing, and electrical fittings.

When your second dwelling has been thoroughly inspected, we will load it onto a flatbed truck and deliver it to your location. In a matter of weeks, the house will be fixed to the foundation, connected to utilities, and ready for you to enjoy. 

 
 

Second dwelling requirements

Limitations on the size of your second dwelling will depend on your local council rules and whether you're in a rural or residential area. In all South Island districts, a second dwelling will require building consent if it is larger than 30sqm and has a bathroom and kitchen. It will likely require resource consent as well.

In most South Island districts, the maximum for second dwellings is set at 70-75 sqm. However, some districts allow up to 90 sqm.

No matter where you are in the South Island, the Genius Homes will project manage the entire operation. As part of this, we can sort all the relevant consents and permits for you. For more information on your local consent regulations, chat with our team or book an onsite consultation.

Benefits of a prefab second dwelling

Building a second dwelling has a reputation for being stressful, messy, and disruptive. If the idea of having builders encroaching on your space for months on end is putting you off, prefab homes are the ideal solution. Benefits include:

  • Efficient manufacturing.
  • Minimal noise and disruption on your property.
  • Fewer weather delays.
  • Full project management by our experienced team.
  • No tradespeople on your site for long periods.
  • Delivered to site as a complete home.
  • No mess or waste on your property.

With our prefab method, the main disruption to your site is when the house is delivered and lowered onto the footing, which is completed in a matter of days. This is followed by basic site work such as final touch ups and connections to utilities. In a few short weeks, we will hand over the keys to your brand new second dwelling.
