10 reasons to knockdown and rebuild .

01. Create your very own personalised home to suit not only your land but your family and lifestyle. When renovating you are limited to the foundations of what already exists, often ending up with significant compromises.

02. Stay within budget and know all costs upfront before you commence construction, when renovating unforeseen issues often arise with areas such as plumbing, electrical and foundation works once you start demolishing existing structures.

03. Create new memories . “We wanted a fresh start and new memories. It’s not the same when you renovate and inherit a world of problems! Budget blowouts are common with an old home like ours. Rebuilding seemed the way to go” . Vini and Sheena

04. Improve the resale value and street appeal with a brand new home fetching a higher sales return than an existing newly renovated home.

05. Build a more energy efficient home  saving you money on bills and future proof your home for your evolving lifestyle.

07. Structural constraints Existing structures will limit your design to increase ceiling heights and change the location of your kitchen and/or bathroom.

08. Be smart with your investment With the average cost m2 when renovating sitting upwards of $3500m2 vs a knockdown rebuild which can be from $2500m2 dependent on your site and finishes. A smaller renovation can often be a great solution and far more cost effective than a knockdown rebuild if you are wanting to add a deck and remodel your kitchen. When families are running out of space though and need to extend out, up or both this is where we commonly see renovation quotes which are very comparable to knockdown rebuild!

09. It's time  “It wasn’t an easy decision as we lived in our home for 6 years and had made wonderful memories but the structures were literally falling down around us!” Heidi

10. Build your forever home.

What size home can I build on my land?

  1. The size home permitted will very greatly depending on approval avenue & land size. There are 2 different approval avenues available to us, Our expert sales & design team alongside our compliance team will walk you through your options to get the best outcome for you.

The first being CDC, an objective state-wide framework which is often faster & less restrictive than council. Due to the objective nature of CDC it is very rigid. There are factors which may mean you do not wish to use this avenue or in some cases such as the site being affected by flood, heritage (even in proximity), medium to high level bushfire or in close proximity to trees in excess of 8m tall we are unable to gain approval through CDC

  1. The 2nd option being approval through your local council & relevant planning controls (DA), councils will traditionally take longer to work through the approval process & may impose additional requirements for the project. However certain projects will gain a superior outcome through a DA approval or indeed will need to gain approval through council due to site or location constraints. We have a large amount of experience guiding projects down this avenue in some of Sydney's "more challenging" councils.

Can I bring my house forward?

This often depends on your neighbouring properties. CDC & most councils use a variation of the "prevailing building line" to determine a front setback. This is often the average distance to the main building line (front of the home) to the boundary of the neighbouring properties each side of the subject home. Our sales & design team have access to technology to help determine this in your initial assessment phase.

My land slopes to the rear, can I build a 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 start from $2,500. 

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 sales estimate and building contract?

Yes, rock is generally the only site cost which remains an allowance when the building contract is finalised.

Can you mange the demolition for us?

Demolition is organised and managed by the owner. You will need to engage the services of a licensed and insured Demolition Contractor as once demolition is complete, we will require a Clearance Certificate. Alternatively, we can put you in contact with our preferred demolition company that can explain the full process to you.  

How much does demolition cost?

The average cost to demolish your property can start from $30,000 and generally takes approximately 7 days (weather permitting.) However, it is strongly recommended that you work with your preferred company to book demolition in early, especially when considering a pool.

Demolition costs vary with the size of the house and costs include: 

  • access to site 

  • hazardous/asbestos removal (if required) Non-professional practice is often an attempt to save substantial tip fees by burying asbestos and other dangerous materials under the site. Your building site would then become a hazardous area and could cost you thousands to clear it up. 

  • rubbish removal. Tip and recycling fees 

  • established fencing between you and your neighbours. You will need to review whether is needs to be removed, which could become a shared cost

  • council or independent certifier costs to approve the demolition which range from $800 - $1,500

When do I sign the building contract?

At Hall and Hart we want to ensure we are giving you the true cost of building your dream home which is why you will sign your building contract: 

  • AFTER you have signed off on your internal and external selections 

  • AFTER your plans have been approved by the authority (Council or CDC) and  

  • AFTER we issue your Home Owners Warranty and Construction Certificate. It is then we require a 5% Contract Signing Fee.  

We give you every opportunity to design the home you want before you are required to sign your contract, ensuring there are no hidden costs along the way.
