Certify 50 homes or 500. We scale with your programme.
"Certification bottlenecks are the biggest cause of delays in residential construction. A certifier who can't process batch CDCs concurrently, or lets one complex lot delay an entire programme, directly impacts your margin. No.1 Building Services eliminates this with dedicated batch processing, parallel lot assessments, and clear service targets and communication across every active site."
Streamlined services,
at scale.
We accelerate bulk residential pipelines with priority services for volume builders.

Frequently Asked Questions
Yes. No.1 Building Services’ batch CDC and Construction Certificate processing capability was purpose-built for volume residential builders operating land release programmes across Greater Sydney and NSW. We regularly manage 20 to 50 concurrent CDC applications across a single client’s programme — processing standard lots in parallel and escalating complex lots (bushfire, flood, heritage) to a specialist assessor without sequencing delays. All batch applications are managed through a dedicated programme account with a single point of contact.
A dedicated building inspection team is assigned to each volume builder account. We operate a next-day inspection scheduling model across all active sites in your programme — with all booking confirmations provided in writing and inspection reports issued the same business day as the inspection. All inspection records, including photographic reports, are available in your centralised project updates. We do not operate a shared inspection pool for volume accounts — your team knows your house types, your construction standards, and your programme.
Volume pricing covers CDCs, Construction Certificates, stage inspections, and Occupation Certificates at agreed per-lot rates, with no hidden fees for standard lots. Complex lot premiums are agreed upfront.
Our team identifies complex lots - including those affected by bushfire prone land, flooding, or heritage overlays - during the programme onboarding stage. These are assessed and processed in parallel to avoid sequencing delays.
