Load Bearing Wall Removal in Toorak

Wall removal to connect living areas is one of the most common structural interventions in Toorak. PBE provides the engineering assessment and documentation required for building permit applications.

Building permit required. Removing a load bearing wall requires a permit under the Building Act 1993. The application must include engineering documentation signed by a registered structural engineer. A builder cannot provide this independently.

Retaining Wall Engineering in Toorak

PBE designs new retaining walls and assesses existing structures for Toorak properties. All designs are produced to Australian Standards and City of Stonnington permit requirements.

Drainage is structural, not cosmetic. AS 4678:2002 requires drainage in all retaining wall designs. Most retaining wall failures in Melbourne are drainage-related. PBE specifies drainage as part of every design.

Site-specific design: soil type, retained height, surcharge loads
Engineering drawings and certificates for building permit applications
Assessment of existing walls showing movement, cracking, or deterioration
Boundary wall documentation for neighbouring property compliance

Extensions and Additions in Toorak

Second storey additions and rear extensions require structural assessment of the existing building and engineering design for all new elements. Some heritage overlays apply, with high council scrutiny of alterations.

Existing structure assessment: footing and wall capacity for new loads
Structural design for new floors, walls, and roof elements
Engineering drawings and calculations for building permit
Underpinning or strengthening recommendations where required
Coordination with architects and building designers throughout

About Toorak

Toorak’s properties range from Federation-era mansions to contemporary architect-designed homes. The City of Stonnington administers planning, and council scrutiny of alterations is detailed. Large footprints, complex structures, and high-value materials mean structural engineering is needed at every stage of renovation and extension work.
