Knockdown Rebuild: Step by Step Guide

Knockdown Rebuild
If you’re happy with the area you live in, but you’ve outgrown your home, there’s no need to pack up and leave. Instead of buying somewhere else, why not consider knocking down your current house and rebuilding a new custom home?

For first timers, the knockdown rebuild process can be a little daunting. But if you’ve got a trusted builder on board, and you know what to expect, it can be a rewarding experience. To give you a breakdown of what’s involved, we’ve put together this handy step-by-step guide.

1. Doing Your Research

While some people look for other properties to knock down, rebuilding the one you’re already in takes care of most of the initial legwork. However, it’s still important to get some ideas about your block before chatting to a builder.

Take a look at the title documents, and check in with the council to see if there are any regulations or issues related to your block of land. Building regulations and council requirements can often change in the time from when your home was originally built. It’s also worth chatting to a real estate agent about the resale value in your area – just in case you end up wanting to sell down the track.

2. Choosing Your Builder

It’s safe to say, rebuilding your home is a big deal. Therefore, it’s important to pick the right builder for the job. Firstly, should you work with a custom home builder or a volume builder? To break it down, a volume home builder will offer you a limited set of options to choose from, while a custom home builder will do everything they can to work around your vision.

If you’re looking for flexibility in budget, materials and overall design, then a custom home is the way to go. Your suburb may command a custom build too, should you be looking to sell later on. Once you’ve decided on a builder, they’ll explain the whole knockdown rebuild process in detail.

3. Deposits and Paperwork

Your next step will be making your first deposit and giving your builder a copy of your Land Title (or proof of ownership) and the Contract of Sale of Land. Once this has been settled, the builder will do a thorough property assessment, site inspection, and soil report. This is all to make sure your block of land is suitable for a knockdown rebuild.

After the tests are completed, you’ll then start finalising your home design. While the design process can vary, a custom home builder will work closely with you and your family, making sure your vision stays within budget and regulations. Look for a builder that has connections to an architect or has an architect in house for best design results.

4. Internal Selections

Once you have your overall home layout finalised, it’s time to move to selection your internal fixtures and finishes. This is where your new home really comes alive and for many people, can be the most exciting part of the entire process. Look for a custom home builder who has qualified interior designers they work with consistency throughout your home and maximum impact.

5. Signing The Contract

Now it’s all coming together. At this step, your builder will prepare an HIA or MBAV new home contract for you to look over. This will include your tender, design specifications, preliminary soil test, site survey, and contract drawings. You’ll need to pass this on to your financial lender to figure out progress payments. For peace of mind, it’s worth getting your lawyer to have a look before signing anything.

5. Demolition Time

With your knockdown rebuild well and truly on its way, the next step is demolition. You can find a company yourself, or your builder may suggest one for you. However, it’s important to a get a few comparison quotes before you commit. That way, you’ll know what kind service each company provides. Before this happens, you’ll need to organise your utilities to be disconnected.

Once the demolition has been done, you builder will organise another soil test, site survey and finalise the slab design. Keep in mind there might be some adjustments to make on your construction plan and site costs.

6. The Rebuild Begins

With all the paperwork approved and building plans ready to go, your builder will start construction. Depending on a number of factors, the custom home build timeline can take anywhere between 9 to 12+ months, and involves a whole new set of steps, from site preparation to handing over the keys.
