FAQs – Granny Flat Builders Christchurch
What is the price of a granny flat in Christchurch?
The cost of a prefab granny flat can range from $70,000-$90,000 installed. Custom builds range from $90,000-120,000 for a basic one-bedroom build, and up to $150,000+ for larger and higher specification builds. The final cost will vary according to the size, layout, site conditions and materials chosen. Comprehensive, itemized quotations are provided after visiting your premises – NO guesstimates!
Does the council need to approve a minor dwelling?
Yes, usually a minor dwelling needs to be built with consent in Christchurch. This includes structural compliance, plumbing and electrical compliance with the NZ Building Code. Certain small structures may be able to be classified as exempt work; however, we strongly suggest that this be confirmed first. We analyze, prepare and process the entire consent procedure for you.
How much time is needed to construct a granny flat?
It normally takes 6-10 weeks to install a prefabricated granny flat when consent is granted. The time to complete a custom build is typically 12 to 18 weeks, depending on the complexity of the design, the time it takes to prepare the site, and the time it takes for council consent for the project. Before we start work, we will provide you with a realistic and clear timeline and update you on the entire construction process.
How big can a granny flat be in NZ?
The Christchurch District Plan contains a set of zoning and gross floor area limits that a minor dwelling cannot exceed. A minor dwelling is generally defined as a dwelling having maximum square metres, setbacks, site coverage and height. The rules may differ from zone to zone as well as from location to location. Your site is evaluated as part of your free consultation, and we will let you know exactly what you can achieve before you commit.
