Why Extend Your Home in Lakemba?
Lakemba is an inner-west suburb with excellent train connectivity and a diverse community. Older housing stock on standard lots provides strong opportunity for knockdown rebuild and duplex development under R2 and R3 zoning.
Lakemba's established streetscape and median house prices of $1.1M–$1.4M reflect a premium location within Canterbury-Bankstown. Building costs sit above the metro average, offset by stronger capital growth and rental returns. Direct rail access from Lakemba station adds genuine value to Lakemba property. 1930s–1960s-era homes in Lakemba often have good structural foundations worth building on. Extensions add living space at a fraction of the full rebuild cost. Class M–S soil (moderately to slightly reactive) is standard for Lakemba — Buildana includes engineered slab design in every quote.
Home extensions across Canterbury-Bankstown suit the area's character housing stock — from 1920s–1960s bungalows in Canterbury and Earlwood to post-war homes in Bankstown and Revesby. Common projects include rear living extensions, upper-floor additions, and modernising period kitchens while retaining character elements. Heritage requirements may apply in some areas. Buildana manages design, approvals, and construction.

How It Works
From First Call to Final Key
We assess your Lakemba home — existing structure, block size (400–600m²), R2 Low Density & R3 Medium Density zoning, setbacks, FSR, and your space requirements. You'll know what's achievable before spending on detailed design.
⏱Our designer works with your existing home's layout — connecting new living areas to existing rooms, matching materials and roof pitch, and maximising natural light. You approve floor plans and 3D renders before we proceed.
⏱All approval documentation prepared: structural drawings, BASIX, shadow analysis, stormwater, and statement of environmental effects (if DA). Lodged and managed through to Construction Certificate.
⏱Extension built from new footings to completion — connecting structurally to your existing home. Class M–S soil design managed. Temporary weatherproofing maintains liveability where possible.
⏱Defect-free inspection, OC issued, 6-year warranty on all new work. Junction between old and new sections waterproofed and warranted. Maintenance guide covers care of new and existing areas.
