Got some site cost questions?


Site costs pay for the preparation of your building block before foundations can be installed. There’s a couple of key points that make up overall site costs:


  1. Infrastructure

Before you can commence work on your site we need to tick a few boxes.


  1. Local building permits and fees
  2. Soil test report
  3. Contour mapping of your site
  4. Builders construction insurance
  5. Home owners warranty
  6. Temporary security fencing

A more detailed breakdown will be provided in your initial quotation from our licensed builder.


  1. Site works

These costs result from the actual physical work required to prepare your site for foundations. I final cost will be detailed for you after the various test have been concluded on your building block.

Some of these test include but not limited to:


  1. Slab upgrade due to soil conditions such as fall/slope of block and level of back filling required to level out your site.
  2. Installation of services such as gas/water
  3. Retaining walls
  4. Extra fill (Soil)
  5. Excess soil removed
  6. Removal of rock or maybe core drilling for slab piers
  7. Estate covenants

Site costs include all the steps necessary in order to prepare your site before construction. These include all regulatory fees and charges, soil testing, cut & filling of soil, retaining walls, rock/debris removal, installment of services and any ancillary items required before construction.

You can break down the cost of site preparation into fixed costs while others are determined on soil test results and/or difficulties the builder may foresee during preparation. An example would be extra drilling depths for concrete piers in order to find solid substrate. These fees can be negotiated in many cases depending on the site.

A more detailed itemization will be provided in full by our licensed builder/s.

Site costs are calculated based on a number of factors. That is why its hard to arrive at a correct figure without prior consultation and site inspection. Some key factors can be:

  1. Problematic soil (Rock, clay, sand can effect movement)
  2. Cut & Filling required
  3. Size of block
  4. Drainage requirements
  5. Soil stability
  6. Length to connect essential services
  7. Retaining walls etc

It’s also important to note that a firm price for site costs will not be available until certified testing reports are made available. Only guesstimates can be provided beforehand.

It’s almost impossible to calculate a correct figure until all the necessary information required is complied. Every land owners building site varies depending geographical location, soils types, size of block and numerous other factors that come into play.

The best way to acquire an approximate figure is by organizing a free site inspection with your Grouse House licensed builder.
