How Long Does a Knockdown Rebuild Take?
Taking on a complete knockdown and rebuild of your home is an exciting yet time-intensive endeavour. A realistic expectation of the typical timeline can help you plan and budget effectively. Many steps are required, from initial demolishing to final move-in – so how long does a full home rebuild really take from start to finish?
In this article, we’ll walk through the key phases and steps that factor into the schedule for a knockdown and rebuild. We’ll look at typical durations and variables that can impact the timeline. With an informed view of what to expect, you can better anticipate the project length and arrange your life accordingly around a complete home rebuild.
Planning and Permitting Phase
The planning and permitting phase lays the groundwork for the demolition and rebuild process. This involves assessing your goals, budget, and scope needs for the new home.
Initial designs are created to help obtain the required permits. The permitting process itself can take 1-3 months, depending on the jurisdiction.
You'll need both a demolition permit to tear down the existing property structure and full construction permits from the local council for the new home. It's important to work with an experienced builder, interior designers, and demolition company familiar with local permitting requirements.
Having all required approvals in place is crucial before proceeding with the knockdown. The planning and permitting phase typically takes 2-4 months in total but can vary based on design complexities and permitting timeframes. Proper planning and paperwork upfront saves significant time down the road.
Knockdown and Site Prep Stage
Once planning permits are secured by the site supervisor, the knockdown and site prep stage can begin. A demolition contractor or demolition specialist will mobilise on-site and safely tear down the existing home.
This demolition phase usually takes 2-4 weeks, depending on the home's size and construction process. The debris is then removed and disposed of properly. The now vacant lot is prepared by clearing and levelling the site for new construction.
Some excavation may be needed to prepare for laying the foundation. Temporary power and utilities are set up if needed. The knockdown and site clearing provides a blank slate and a stable base to rebuild. If your old house needs major renovation, you can save money by knocking it down and starting fresh.
Altogether, plan on 4-8 weeks to complete the demolition projects and fully prep the site, contingent on weather delays or undiscovered issues beneath the original structure. Careful site prep paves the way for efficient rebuilding.
Rebuild Construction Phase
The rebuild construction phase is the project's longest and most intensive part. It involves building the full custom home from the ground up.
First comes laying the foundation and framing the structure. The roof goes up, followed by exterior finishes like siding, windows, and doors.
Mechanical systems like electrical, plumbing, and HVAC are roughed in. Insulation, drywall, paint and other interior finishes are completed. Cabinets, countertops, fixtures and flooring are installed.
The expected duration for each step varies, but altogether, plan on 6-10 months for the primary rebuild construction phase. However, this is also the most vulnerable to delays based on weather, crew availability, materials supply, and other factors.
Careful project management and scheduling are key, but some delays are often unavoidable. Be prepared for this core construction phase to take up to a year in total.
Completing Your Knockdown Rebuild Process
The final stage involves finishing touches to complete the brand-new custom home. Final inspections occur for structural, electrical, plumbing, and other required permits.
Punch list items are addressed, and any last deficiencies are fixed. Exterior work is finished, such as a driveway, patios, walkways, and landscaping.
Interior design elements are completed and cleaned for move-in ready status. Plan on at least 4-6 weeks at the end for inspections, approvals, clean up, and closing out the permit process.
After over a year of demolition and construction, this last phase ties up loose ends. Once the final occupancy permit is issued, you can move into your stunning new dream home! A clear completion checklist ensures no details are missed before enjoying your rebuilt abode.
Key Factors That Impact Timing
While the general phases and durations provide an estimated timeline, several variables can shift the schedule significantly. More complex demolition and custom designs take longer upfront.
Permitting can drag on if plans require revisions or municipalities are backlogged. Material shortages, weather delays, or contractor availability affect construction timeframes.
Changes mid-project also push out the finish line. And undiscovered underlying issues like asbestos or compromised foundations can halt work.
For major rebuilds, pad at least six months of buffer into your plan. Having flexibility helps navigate unpredictable factors.
Maintain realistic expectations, build in contingencies, and work closely with your project lead for ongoing schedule updates. With large-scale demolitions and rebuilds, adaptability and patience are key to success.
What's the Typical Start to Finish Timeframe?
A complete home knockdown and rebuild is a lengthy endeavour, often taking 12-18 months from initial plans to getting your certificate of occupancy. While every project is unique, understanding the key phases, from permitting to construction, allows you to anticipate the road ahead. But in many cases, a rebuild is more cost-effective per square meter than a major renovation.
