Site Analysis

Understanding all the features of a site, using and protecting the best, and minimising the impact of the worst.

Site Analysis

Understanding the site is the first step towards designing or substantially renovating a house that will minimise its impact on the environment, minimise the use of resources and be comfortable and healthier to live in.

You will need to distinguish between macro (regional or large-scale) effects and micro (site-specific) effects.

You will need to understand site characteristics that are specific to the site (such as topography and landscape features) and broader local or regional effects such as regional climate.

In addition to physical aspects such as sun, wind or ground stability, look also for any covenants or encumbrances on the land title. These can limit what you can do on a site. Covenants may place restrictions around things like the building materials or colour schemes used on a building. They can also apply to the land around a building, by limiting the height of trees or prohibiting clotheslines that are visible from the street, for example. Covenants often apply to new suburbs or developments.

A land title may also contain an easement. This typically covers a neighbour or local authority running an underground gas, water or sewerage pipe through a property. This limits the use of the land where the pipe runs through.

In addition, it will be necessary to understand relevant Resource Management Act and District Plan requirements.
