Although not an assessment, we touched on non-consent buildings - Light Timber Models with a footprint less than 10sqm. I have a big interest in small spaces, and came up with variations of a single 10sqm meter design, that is visually effective, while also manageable to construct.
This design would make for a great guest room or office, having the privacy of being detached from the existing dwelling, and creates extra space and property value. - "This exemption covers the construction of small buildings such as garden sheds, cabins or sleepouts." -NZ Building Act 2004
