A knockdown rebuild in Regents Park costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Cumberland City Council approvals, and construction under one fixed-price contract.
Regents Park Knockdown Rebuilds
A knockdown rebuild in Regents Park suits the aging 1950s to 1970s stock a walk from the station. The homes sit on standard blocks in an affordable, well-connected suburb, so a rebuild gives you a modern custom home without a premium land cost. The era of the stock means the demolition is the main thing to plan.
The ground carries reactive clay, so the new slab is engineered off geotech. The 1950s to 1970s stock commonly carries asbestos, so a licensed strip-out and clearance certificate lead the demolition. The blocks also suit granny flat additions where a rebuild is not the goal.
What I check first on your Regents Park knockdown rebuild: any asbestos in the demolition, the reactive clay for the new slab, and the block's scope for your new home. Those decide the play.

Affordable rebuild near the station
Regents Park's aging 1950s to 1970s stock on standard blocks suits a knockdown rebuild, and its own station plus an affordable land price mean the numbers work well: your budget goes into a modern custom home rather than a premium land cost. It resets a tired home entirely rather than renovating around aged bones.
The rail connectivity keeps the location convenient, so a rebuild that lifts a tired home to modern standard is well supported here.
Reactive clay and asbestos
The reactive clay under Regents Park means the new slab is engineered off a real geotech to stay stable against clay movement. The 1950s to 1970s stock commonly carries asbestos, so a licensed strip-out and clearance certificate lead the demolition before the rebuild. I map both as part of the feasibility.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free site inspection of your Regents Park property. We check lot dimensions, Cumberland City Council's planning controls, existing home condition, and potential asbestos. Written assessment with budget estimate within 5 business days. KDR is the chance to get the design right — the new build doesn't have to mimic the original layout. We start from your block's strengths (orientation, slope, views) and your family's brief, then design the home the original lot always deserved.
⏱The Regents Park construction phase. Fixed price, programmed, supervised. Licensed demolition of existing 1950s–1970s-era dwelling. Asbestos removal by certified contractors (if present). Site cleared, levelled, and ready for new slab. Typically 1–2 weeks. Your new home goes up on the cleared site. Engineered slab sized for Class M soil, frame, roof, fit-out, kitchen, bathrooms, flooring, painting, driveway, and landscaping. Quality inspections at every stage.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Handover pack: OC, structural certificates, BASIX, appliance manuals and warranties, paint colour schedule, maintenance plan, and the keys. Six-year structural warranty kicks in from OC date — keep the documentation safe for any future sale.
