Plus, a new home built with energy-efficient designs can result in significant savings on power bills for years to come.

THE STRESS-FREE Knockdown Rebuild Process

Reduce stress by getting Alexacon to help with
the whole process.

Free Inspection & Quote

One of our experienced team will come visit you onsite to assess your block and determine the best possible design solution for you. Based on your individual requirements and needs we will prepare a detailed costing for your approval.

Permits & Approvals

Alexacon will then help arrange and gain all the necessary permits and approvals with the Central Coast Council. We will then also advise appropriate timeframes for when you’ll need to move out of your existing home.

Move out & Demolition

If you’re currently living in your existing home it’s time to move out – we can even help recommend a removalist company.

Work is now underway and the demolition starts.

New Home Construction

Once your old house is gone, the build process begins. We will provide consistent updates throughout the entire process and you’ll be able to see your new home coming to life as the new slab is poured, the roof is pitched and the brickwork begins.


Once construction is complete we will undertake a walkthrough and final inspection with you.

If there’s any outstanding items, these will be addressed and seen to then it’s time to get your keys and move into your brand new home!
