A home renovation in Seven Hills costs $100,000–$500,000+. Kitchen from $30K, bathroom from $20K, full renovation from $150K. Buildana manages design, Blacktown City Council approvals (where required), and construction under one fixed-price contract.
Seven Hills Renovation Specialists
A home renovation in Seven Hills modernises solid 1960s to 1980s stock on generous 550 to 700m² blocks — reconfiguring dated floor plans, opening up living areas, updating kitchens and bathrooms, and often extending at the rear where the block gives room.
The technical constant is the Class H reactive clay: any structural change checks the existing footings against clay movement and underpins where needed, because an extension loaded onto tired footings on reactive ground cracks within seasons.
Where the older home carries fibro in eaves or additions, a licensed strip-out leads that part of the work. The station and motorway access keep the suburb practical.

Solid stock, room to extend
Seven Hills' 1960s-80s homes were built solid, so the renovation budget goes into layout, light and living space rather than structure — and the generous 550 to 700m² blocks give a rear extension real room.
It is a family suburb near the station and the M2/M7, so a renovation lifts the home while keeping you settled.
The reactive clay check
The Class H reactive clay means any structural change checks the existing footings and underpins where needed — the detail that keeps a renovation crack-free through the seasons.
Where the older home carries fibro, a licensed strip-out leads that part of the work, priced into the scope.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your Seven Hills home — existing condition, renovation scope, structural requirements, and budget. You'll receive a clear overview of costs and timeline before committing. Design phase includes floor plan modifications, 3D kitchen and bathroom renders, material palettes, and electrical layout. You approve every detail before construction begins.
⏱The Seven Hills construction phase. Fixed price, programmed, supervised. For renovations that need DA or CDC, we lodge structural drawings, hydraulic if wet areas move, BASIX if envelope changes, and SEE if DA. For pure cosmetic work, no lodgement, no permit fees — straight to scheduling trades. Fixed-price renovation from demolition of existing fittings to final finish. Staged programme keeps parts of your home liveable. All trades coordinated by your project manager with weekly updates.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Handover includes a defect walk-through where we mark any final touch-ups, complete them within a week, and re-inspect. The end-state is genuinely finished — not handed over with a list to chase trades back for.
