Knockdown Rebuild On A Sloping Block

Everything you need to know about a knockdown rebuild on a sloping block

Thinking of knocking down your house and rebuilding the home you’ve always wanted? If your house is on a hill, you might be wondering about the complexities of a knockdown rebuild on a sloping block. You might also have started the process of looking into demolition and potential site costs required to level the block including excavation and expensive isolated retaining walls. 

The good news is that a knockdown rebuild on a sloping block doesn’t have to be complicated! At Montgomery Homes, we can build on almost any site, no matter how steep. We’ve developed smart and intuitive building techniques to maximise the space and build the home you’ve always dreamed of. 

In this article, we share all the essential information you need to know about a knockdown rebuild on a sloping block and answer some common FAQs about the process.

Is a knockdown rebuild on a sloping block too complicated?

If your block has a very steep gradient, you might be worried about the complexities of a knockdown rebuild project. The good news is that you don’t need to be concerned about the logistics of the project — Montgomery Homes are the sloping site specialists in Newcastle, Sydney and the Central Coast. We’ve built hundreds of beautiful, functional homes on blocks that slope uphill, downhill and to the side!

Split level homes make the process quite simple. These clever home designs follow the natural slope of the land — rather than cutting deep into the block and creating an artificially level site, we follow the slope and use the excavated soil to flatten and level the land. This eliminates the need for expensive retaining walls and creates a unique floor plan with multiple spacious levels.

Does it cost more to complete a knockdown rebuild on a sloping block?

A common misconception is that a knockdown rebuild on a sloping block costs more than a knockdown rebuild on a level site. This is not necessarily true — the cost for your new home will vary depending on the home design, the demolition costs and any additional upgrades you choose. 

Before making the decision to build or place a deposit, our construction team will complete a free site inspection and determine any additional site costs so there are no unexpected surprises along the way. We’re transparent about our pricing from day one so you can feel confident about the entire building process. 

Many of our clients have said their knockdown rebuild project was the best decision they ever made financially. Contact us for more information about potential site costs or to book a free site inspection.

What is the knockdown rebuild process?

The knockdown rebuild process is relatively simple once the demolition has been completed — in the video above, we share the knockdown rebuild process in a timelapse fashion, so you can see one of our client’s knockdown rebuild projects from start to finish.

Below, we share a detailed breakdown of the knockdown rebuild process.

What do I need to know about retaining walls?

If you’re building on a sloping block, you may be considering the cost of retaining walls. Retaining walls are designed to protect your home, boundaries and adjoining properties, while also keeping the landscaping and soil where it’s meant to be. We recommend an integrated retaining wall — these retaining walls are built with concrete blocks or bricks and form a part of your home’s construction, sitting tight against the external walls of your house.

Drainage is possible through this kind of retaining wall and creates a natural pathway for water to run down the side of your home, following the natural slope of the land. This is advantageous for both you and your neighbours, especially if your neighbours have a pool or outdoor entertaining area.

The benefits of a split level home design

As well as being affordable, knockdown rebuilds on sloping blocks come with a lot of attractive advantages — for example, a split level home design (a standard in a sloping block design) adds a fascinating dimension to your home. Even a seemingly single-level home can have stairs and multiple levels, following the natural contour of your block. This allows for an abundance of natural light flowing through your home!

Besides this, the benefits are boundless:

  • Less cut and fill required for site preparation
  • Separate living areas on different levels 
  • Preservation of natural drainage
  • Enhanced outlooks and views
  • A more manageable driveway
  • More affordable land choices
  • Fewer retaining walls
  • A more manageable backyard for landscaping.
