Property Types We Work With in Narre Warren

Narre Warren’s building stock reflects one of Melbourne’s fastest growing corridors, with a mix of established homes and active new development. Principal Built Engineering works across the full range of property types found across the area.

New Build, Deck and Dual Occupancy Certification

Narre Warren’s growth corridor means many enquiries involve new construction rather than renovation of an existing home. PBE provides independent structural certification for owner-builders and clients working with volume builders, as well as certification for decks, pergolas and other structures added to newer homes.

• Independent structural design and certification for new residential builds
• Deck and pergola structural certification for existing and new homes
• Structural engineering for dual occupancy and multi unit developments
• Footing design for estate lots, including fill and reactive clay conditions

• Substructure: footings, sub-floor framing, drainage conditions
• Superstructure: external and internal bearing walls, floor framing
• Roof structure: rafters, tie members, visible movement or distress

Service Area Coverage

Principal Built Engineering serves Narre Warren and the surrounding City of Casey area, including Berwick, Hallam, Hampton Park, Cranbourne, Fountain Gate and Endeavour Hills.
