Merc.Build builds luxury custom homes and knockdown rebuilds in St Ives under Builders Licence 377744C. St Ives' large garden blocks and ageing mid-century stock make it one of Sydney's strongest suburbs for replacing an old home with a purpose-designed family residence.
St Ives is a suburb of quarter-acre thinking: wide frontages, established gardens, streets under a canopy of gums. What has aged is not the land but the houses on it — and that gap between block and building is exactly what a well-run rebuild closes.
The strongest rebuild arithmetic in Sydney
A 1960s brick home on nine hundred square metres of St Ives garden is usually worth less than the cost of dragging it to modern standard — while the same budget builds a new home designed precisely for the family and the block. Single-level living, north-facing family rooms, pools placed for sun rather than leftover space: the brief writes itself when the page is blank.
Gardens and tree canopy as design partners
Ku-ring-gai's tree controls are serious, and rightly — the canopy is the suburb. We survey significant trees first and design the home around them, using their shade and screening as assets. The result sits in an established garden from day one instead of waiting a decade for landscaping to catch up.
Multi-generational by design
Many of our St Ives briefs now include a self-contained wing for parents or adult children. Large blocks absorb this graciously — separate entries, acoustic separation, shared gardens — when it is designed in from the start rather than converted later.
Questions.
Is St Ives good for a knockdown rebuild?
It is one of Sydney's best suburbs for it: large, regular blocks, ageing post-war housing, and Ku-ring-gai planning controls that generally support a well-designed replacement home. The main considerations are tree protections and streetscape character. Merc.Build runs feasibility against the controls before design, and manages demolition through to handover under one contract.
How long does a St Ives knockdown rebuild take?
Typically 20–28 months end to end: two to four months for feasibility and demolition approvals, four to eight for design and the CDC or DA pathway, and twelve to sixteen months of construction for a substantial family home. Merc.Build fixes the construction programme in the contract and reports against it monthly.
