WHAT SIZE HOME CAN I BUILD ON MY LAND?
There are 2 different sets of legislation that we could choose to use. Our expert sales and design team are all very knowledgeable in this field and can walk you through your options.

  1. The first being CDC which will allow for a size home based on a formula that correlated to your land size.
  2. The other option is through the council rulings which normally works on a percentage based on the size of your land.

CAN I BRING MY HOUSE FORWARD?
This quite often depends on the front setbacks of the neighbouring properties. Most councils (not all) will allow you to build to the average front setback of the neighbouring properties on either side of your dwelling.

MY LAND SLOPES TO THE REAR OF THE PROPERTY CAN I BUILD A STANDARD 2 STOREY HOME? 
This is not something to worry about and can sometimes be a blessing in disguise, when your property slopes to the rear we can introduce a few steps throughout your hallway leading down to increased ceiling heights in the rooms towards the rear of your home. This will provide you with a luxurious and spacious feel to the main living quarters of your new home. You can find out more about building on sloping blocks here.

WHAT IS THE AVERAGE COST/SQM?
Cost will be dependent on your site conditions, materials used in your build and internal fixtures and fittings. Generally, on a standard level block the average cost/sqm can range from $1,600 - $1,800.

WHAT ARE SITE COSTS AND HOW MUCH WILL MINE COST?

Site costs include but are not limited to:

  • creating a level platform to build your slab on making your house structurally sound
  • importing or exporting soil to provide you with a level platform
  • running new services such as sewer connections, stormwater connections and potential on site detention for stormwater (OSD), services and connections for gas, and water, provide you with your own private power pole, running the new electrical connection underground to your house
  • rainwater tanks to meet hydraulic requirements
  • construction site fencing
  • scaffolding for a 2 storey home

Each house and site is individually assessed based on its requirements. Our sales and design team will be able to provide you with a fairly accurate guide to your requirements before ordering specific reports.

DO YOU INCLUDE SITE COSTS IN YOUR TENDER ESTIMATE AND FINAL TENDER?
Yes, we provide detailed site cost based on numerous reports we gather to confirm the overall costs at the time of tender. This means no nasty unforeseen surprises later down the track.

CAN YOU LOOK AFTER THE DEMOLITION FOR US?
We partner with a trusted demolition team which is an external company. We will provide you with a quote from the company and will assist in the communication and timing to ensure everything is completed in time to start your new build.

ARE THERE ADDITIONAL COSTS?
There are a few costs that council charges that should be considered towards your overall budget. These costs include:

  • Section 94 contributions fees which is a council fee charged when constructing a new dwelling. This fee can differ from council to council but a rough rule of thumb would be 1% of the build cost
  • Additional costs will be incurred for granny flats or dual occupancy
  • There may also be council bonds applicable or Sydney Water Section 73 fees if you are extending or relocating their services.

WHEN DO I SIGN THE CONTRACT?
We want to ensure we are giving you the true cost of building your dream home which is why you will sign your contract:

  • AFTER you have signed off on your internal and external selections
  • AFTER your plans have been approved by the authority
  • AFTER we issue your Home Owners Warranty and Construction Certificate
