A home extension in Wheeler Heights costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Northern Beaches Council approvals, and construction under one fixed-price contract.
Wheeler Heights Home Extensions — Fixed Price
From the eastern fall of Wheeler Heights you can see Long Reef — one storey up, you can see it from your living room. That's the pitch for a first-floor home extension here, and it's why so much of the suburb's 1950s–1970s brick stock on 500–800m² blocks is growing a second level. In a $2.4M–$3.6M market, the view floor is the renovation that actually moves the valuation.
Post-war brick from this era carries an upper storey once an engineer confirms footings and wall ties — some houses take it directly, others need targeted steel, and we don't quote until we've looked. The sandstone underneath adds $40K–$100K to any ground-floor dig, which quietly strengthens the case for building up instead. Book a structural check and find out what your roofline is hiding.
Buildana manages the complete home extension process in Wheeler Heights — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Long Reef from the living room
Wheeler Heights' eastern fall puts Long Reef one storey up — which is why so much of the post-war brick is growing a second level, and why the view floor is the build that actually moves the valuation here.
In a $2.4M to $3.6M market, the maths usually lands in its favour.

The sandstone under any ground-floor dig quietly strengthens the case for up. All priced upfront.

How It Works
From First Call to Final Key
Walk through your Wheeler Heights home with our designer and structural engineer. We measure, photograph, and check the bones — footings, frame condition, roof structure. The cost estimate that follows is grounded in what we found, not a generic per-m² number.
⏱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.
⏱Most rear extensions in Wheeler Heights qualify for CDC — cleaner, faster, no neighbour notification. Second-storey additions typically need DA through Northern Beaches Council because of overshadowing and privacy assessments. We choose based on your design, not on what's easier to lodge.
⏱Extension built from new footings to completion — connecting structurally to your existing home. Class Hawkesbury Sandstone soil design managed. Temporary weatherproofing maintains liveability where possible.
⏱Walk through the completed extension, confirm finishes, collect your OC. Six-year structural warranty covers all new work including the junction with your existing home. Maintenance guide provided.
