Yes, you do require a demolition permit but this should be organised by your demolition contractor.

We will support and provide you with assistance with this step of the process. Once we have established that your site is ready to prepare for your new home, Sienna Homes can provide you with a list of reputable demolition companies that have been used and recommended by other clients and an optimal demolition timeframe

A Building Permits is a specifc permit that is required before you can start the construction of your home. Sienna Homes will arrange this permit on your behalf.
In some instances, a Town Planning Permit may also be required and this will need to be obtained before a building permit can be issued. We will be able to advise you whether your home will require a Town Planning Permit.

A Town Planning Permit may be required for things like removal of vegetation or it may be required for the type of home you are building.

Building envelopes set design parameters for what you can build on your allotment. It is like an outline of where you can build on your block.

Our New Home Consultant will assess the proximity of power lines near your existing house and discuss any special requirements with you.

A site survey is an inspection of the build site to gain information on where the home will sit on the block and if there are any site restrictions or obstructions like vegetation or that need to be addressed prior to construction.

A soil test is conducted by a Geotechnical Engineer who
drills down into the ground at your build site and takes a sample to review the ‘reactiveness’ of your soil at various depths. Soil reactivity is essentially a  measurement of how likely it is that the ground under your home will move. It is
important to understand how stable the soil is as this will determine the kind of footings your home will need. It is really important that your home is built on an appropriate foundation. If your soil is subject to a high level of movement, your home will require stabilising footings. Usually moisture is the main cause of movement so sandy rocky soil is usually more stable than clay.

Below is a guide to the different classifcations:

• Class A – Stable, non-reactive: possibility of very little or no ground movement as result of moisture change (often sand and rock sites)
• Class S – Slightly reactive – Clay sites with a chance of slight ground movement from moisture changes
• Class M – Moderately reactive – clay or silt sites with the possibility of moderate ground movement
• Class H1 & H2 – Highly reactive clay sites with a possibility of high to very high ground movement
• Class E – Extremely reactive – possibility of extreme ground movement from moisture changes
• Class P – Problematic sites that include flled, soft soils, such as soft clay or silt or loose sands; landslip; mine or other abnormal moisture conditions or sites which cannot be classifed otherwise.

Rock removal – If rock is encountered, a provisional sum will be estimated for the cost of removal as it is diffcult to determine the extent of rock until construction commences.
