Our off-market realty partners are presenting a superb duplex site opportunity in Bentleigh East—right in the coveted McKinnon School Zone. We completed a high-level feasibility, and the numbers are compelling: projected profit exceeds $400K.


This rare off-market site is ideal for investors, downsizers, developers, or owner-occupiers seeking premium living in one of Melbourne’s most tightly held suburbs.


A Modern Duplex Concept Designed for Lifestyle + Profit


The proposed duplex has been designed for bright, airy, modern living with flexible buyer-driven upgrade options including:


  • 4 bedrooms, zoned living and 3 bathrooms

  • North-facing living for year-round light

  • 120–140 sqm private garden with room for a pool

  • Optional 8-Star sustainability package for eco-conscious buyers

  • Flexible layout ideal for live-in-one, sell-the-other strategies


This combination of location, orientation, and design quality maximises both lifestyle and resale value.

Why This Off-Market Site Stands Out


1. Prime Location Advantage

  • Located inside the McKinnon Secondary School Zone, one of Melbourne’s highest-demand education catchments.

  • Off-market status means reduced competition and greater negotiation leverage.


2. Lifestyle Flexibility

  • Buyers can select optional upgrades (pool or sustainability package), strengthening resale outcomes.

  • North-facing orientation ensures bright, comfortable living spaces.


3. Strong ROI

High-quality design + smart value engineering + an A-grade suburb


4. Sustainability & Passive Design as a Value Driver

Eco-performance is becoming a key differentiator in the duplex market—here, it’s integrated intelligently and cost-effectively.



Passive & Sustainability Design Moves (Value-Focused)


These features deliver exceptional energy performance without excessive cost uplift:


  • Eaves & shading tailored to block high summer sun and invite winter warmth

  • Thermal mass where it adds value (slab under key living areas only)

  • Targeted high-performance glazing to north-facing living and master bedroom

  • Cross-ventilation via east–west operable windows and clerestory vents

  • Rainwater reuse for toilet + laundry

  • Hydronic heating, heat-pump cooling, 6.6 kW solar (upgrade)

  • Thermally broken double glazing (upgrade)

  • EV-ready garage

  • 8-Star NatHERS rating (upgrade)


These features boost buyer demand, reduce energy bills, and enhance long-term asset value.


Value Engineering Levers to Improve Margin


Practical, cost-efficient ways to protect profit while maintaining premium quality:


  • Rationalise bathroom finishes (keep one premium ensuite) — save $15–25K

  • Simplify façade with brick + feature entry — save $20–30K

  • Selective double glazing (north living + master only) — save $10–18K

  • Timber-framed upper level + slab only under main living — save $20–40K

  • Simplified landscaping—focus on usable lawn + screens — save $10–15K

  • Swap hydronic heating for high-efficiency heat pump — save $15–25K

  • Solar with optional battery upgrade — save $5–10K upfront


These strategies retain market appeal while keeping build costs controlled.


Final Takeaway


This off-market Bentleigh East duplex site is a rare combination of:

  • A-grade school zone

  • Strong projected profit

  • Flexible upgrade pathways

  • Eco-smart design

  • High buyer demand and limited competing supply


With thoughtful design and strategic value engineering, this project delivers both premium living and excellent financial outcomes.
