Merc.Build is a licensed luxury home builder (Builders Licence 377744C) working in Matraville and Sydney's south-east. Our completed Matraville project is Hillary at 12 Hillary Parade — a double-brick Torrens-title duplex behind a sculpted breeze-block screen, sold in 2025 for $2.925 million.
Matraville sits in the quiet triangle between Maroubra's surf, Malabar's headland and the Port Botany working harbour — a suburb of generous post-war blocks that spent decades overlooked and is now one of the south-east's strongest rebuild markets. Ten minutes from the beaches and fifteen from the airport, its wide, flat lots take duplexes and family homes that simply cannot fit on the tighter streets further north.
Hillary — our completed Matraville project
Hillary, at 12 Hillary Parade, is what we believe a Matraville duplex should be: double brick and concrete construction, a white-brick street face screened by a curved breeze-block veil, and interiors by SICI Design that run herringbone oak floors into a travertine kitchen with Smeg Dolce Stil Novo appliances. It sold in March 2025 for $2.925 million — a suburb benchmark that reflects what disciplined design and construction return on Matraville land.
The south-east's best duplex arithmetic
Matraville's original housing sits on blocks commonly ranging from 400 to 700 square metres, zoned under Randwick City Council controls that support dual occupancy on suitable lots. Torrens-title duplexes work particularly well here: two full-sized homes, each with a garden and garage, on land a single cottage previously occupied. We run the feasibility — frontage, floor space ratio, driveway grades — before any design is drawn.
Coastal edge, industrial neighbour
Building well in Matraville means detailing for two exposures at once: salt air rolling off Malabar and Maroubra, and the working traffic of the port precinct. We specify marine-grade fixings, robust brick and concrete envelopes, and acoustic glazing where sites face the busier corridors — so the home stays crisp outside and calm inside for decades, not seasons.

Questions.
Can I build a duplex in Matraville?
On many Matraville blocks, yes — Randwick City Council permits dual occupancy and Torrens-title subdivision on lots that meet frontage and area controls, and the suburb's wide post-war blocks frequently qualify. Our completed Hillary project at 12 Hillary Parade is a current example. Merc.Build checks your block's eligibility against the controls before any design work begins.
What does it cost to build a luxury duplex in Matraville?
A high-end double-brick duplex in Matraville typically runs $4,500–$6,000 per square metre of construction, with each completed dwelling generally representing $1.3–$1.8 million in build cost depending on scale and finishes. As a value reference, our Hillary duplex sold for $2.925 million per dwelling in March 2025. Merc.Build provides a line-item estimate after a site inspection.
