Property type
Residential Estate
Area covered
85 m² waterproofing, 72 m² new roofing, 72 m² new ceiling, 182 m² floor tiling, 182 m² ceiling painting, 107 m² wall painting
Materials used
Torch on bituminous membrane, bituminous UV resistant silver paint, structural steel I beams, roof trusses, roof joist hangers, shatterproof roofing, Rhinoboard ceiling materials, concrete, screed, aluminium stacking doors, aluminium windows, interior and exterior paint
The problems
1. Existing layout restricting the planned home extension
The property's existing walls, roofing, ceilings and floor finishes needed to be removed to accommodate a substantial home extension.
The renovation required major structural alterations, including the installation of steel support beams and new brick columns. The existing roof structure also needed assessment to determine which trusses required replacement.
2. New roof requiring reliable waterproofing
The extension required a new roof structure with effective waterproofing protection.
Without a properly installed waterproofing system, roof surfaces and junctions can become vulnerable to rainwater penetration, potentially damaging ceilings and interior finishes.
The project required 85 m² of torch on bituminous waterproofing, together with a UV resistant protective coating across 72 m².
3. Structural support for the extended living space
Removing existing walls and altering the roof created a need for additional structural support.
The extension required multiple structural steel I beams, including a welded corner beam, together with two new brick columns.
These components formed part of the structural design necessary to accommodate the revised building layout and roof construction.
4. Interior surfaces requiring complete reconstruction
The renovation involved extensive alterations to the property's ceilings, flooring and internal finishes.
New ceiling construction, floor tiling and painting were required to integrate the extended areas with the existing home.
A recessed patio floor also required concrete and screed work to establish the intended finished floor level.
5. New openings and exterior finishes
The revised layout required new aluminium folding stacking doors and windows.
The exterior kitchen wall and new front face also needed painting to create a consistent appearance between the new construction and existing property.

Project results
1. A successfully extended and renovated home
The renovation delivered the planned structural alterations, creating a substantially reconfigured living space with new roofing, ceilings, flooring and aluminium openings.
The completed work integrated the new construction with the existing home, providing renewed interior and exterior finishes.
2. New roof successfully waterproofed
The new roof received 85 m² of torch on bituminous waterproofing, establishing a protective barrier against rainwater penetration.
The completed waterproofing was successful, with no roof leaks reported following installation.
The waterproofing was complemented by UV resistant silver paint across 72 m², providing additional protection against sunlight and weather exposure.
3. Structural alterations successfully completed
The structural renovation incorporated steel I beams, brick support columns, roof trusses and joist hangers.
These elements formed part of the new structural arrangement supporting the extended living areas and roof construction.
4. Restored interior with new ceilings and flooring
The renovation included 72 m² of new ceiling installation, 182 m² of floor tiling and extensive ceiling and wall painting.
The completed finishes created a consistent appearance across the renovated interior and extended areas.
5. Modernised openings and exterior appearance
The new charcoal aluminium folding stacking doors and windows updated the property's openings and complemented the revised layout.
The exterior kitchen wall and new front face were also repainted, creating a coordinated finish between the extension and existing structure.
