Knockdown Rebuild Holroyd — Demo to Handover in 12 Months
Holroyd 2142 KDR with tight programme: demolition (3–4 weeks), new home (24–40 weeks). CDC fast-track or Cumberland City Council DA. Weekly progress updates.
Holroyd KDR — Single Contract, New Home
A knockdown rebuild in Holroyd suits the post-war stock on standard 450 to 650m² R2 and R3 blocks, in a quiet residential pocket close to the Merrylands and Granville centres. The 1950s to 1970s homes are aging into rebuild territory.
The ground is Class M shale, which takes a standard engineered slab off a geotech. The post-war homes usually carry asbestos, so a licensed strip-out and clearance certificate lead the demolition.
On the R3 blocks over the 600m² minimum, a duplex can be worth costing, so I run both feasibilities where the block allows.
We rebuild fixed-price, licence HBL 487805C. Get our knockdown rebuild feasibility before you commit.
Buildana manages the complete knockdown rebuild process in Holroyd — from site assessment and architectural design through to DA or CDC approval, demolition management, and fixed-price construction to handover. One builder, one contract, one new home.

Quiet, central pocket
Holroyd is a quiet residential suburb well placed between the Merrylands and Granville centres. On standard 450 to 650m² blocks, the post-war stock is aging into rebuild territory, so a knockdown resets a dated home into a modern one.
It keeps you central to the wider Cumberland area while staying in a settled street.
Asbestos and the duplex question
The Class M shale takes a standard engineered slab off a geotech. The post-war stock usually carries asbestos, so a licensed strip-out and clearance certificate lead the demolition.
On the R3 blocks over 600m², I cost the duplex alongside the single rebuild so you can see both returns.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your Holroyd block — lot size (typical 450–650m²), R2 Low Density & R3 Medium Density zoning, setbacks, FSR, and existing dwelling condition. Asbestos survey included. You'll know feasibility and budget before committing. Complete design package: floor plans, elevations, 3D renders, structural engineering, geotech, BASIX, stormwater, and all documentation Cumberland City Council requires. Approval managed start to finish.
⏱The Holroyd construction phase. Fixed price, programmed, supervised. Pre-demolition: dilapidation report on adjoining properties (protects you against unfounded damage claims), service disconnections, asbestos clearance, neighbour notification. Then 1–2 weeks of physical demolition with material sorted at site for recycling where possible. Fixed-price construction: engineered slab, frame, lock-up, fit-out, external works. 8–12 months depending on size. Weekly progress reports with photos and milestone tracking.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Same address, completely different home. Permanent gas, water, electrical, NBN reconnected and tested. Council waste collection re-registered. Mailbox reinstalled. Move-in ready, not move-in plus 100 small jobs.
