Surrey Hills maintains some of Melbourne’s most stringent heritage controls. The suburb’s housing stock tells nearly 180 years of Australian domestic history, but carries structural quirks and regulatory implications.
Victorian homes, for instance, offer extraordinary presence and prestige, but their compartmentalised layouts and dark central zones make them difficult to work with. Edwardian and Bungalow homes tend to be more forgiving, with wider allotments and better side access. But they come with their own challenges: moisture management, thermal inefficiency, and the ever-present tension between the character of the original home and the functionality a modern family actually needs.
In a suburb like Surrey Hills or neighbouring Glen Iris, the price gap between a four-bedroom and a five-bedroom home can exceed $1.2 million. The stamp duty alone on a $3 million property in Victoria sits at around $160,000. A well-executed rear extension means additional space and long-term equity gain for a fraction of the relocation cost. Staying put and building well is the play; let’s see how you can do that efficiently and effectively.

What are Boroondara’s renovation rules?
Boroondara Council’s Heritage Policy operates through a grading system that determines what you can and can’t do. Homes classified as Significant Heritage Places face the most stringent controls; new openings in the principal façade or changes to visible roof forms are generally off the table.
Contributory Heritage Places allow more flexibility, particularly at the rear, provided any new additions are visually recessive from the street. The Heritage Overlay triggers a requirement for a Planning Permit for almost any external alteration, including tree removal in some zones.
It sounds daunting, and without the right experience, it can be. Engaging with the council early can prevent unnecessary redesign costs. As a general rule, the earlier you surface the issues, the cheaper they are to solve. Our team has learned this over years of experience and always ensures that planning risks are identified before they become budget blowouts.
The technical complexity of heritage renovation
Council approvals are one thing, but the construction itself is another. A good renovation pays attention to the junctions between old and new, in the materials, in the decisions that only become visible (or problematic) years down the track.
One example we love is thermal performance. Heritage homes were not designed to meet the energy standards we expect today, and their high ceilings, original single-glazed windows, and lack of insulation make them expensive to heat with conventional ducted systems. Hot air rises; in a room with 3.6-metre ceilings, that means warmth pools where nobody lives. Hydronic heating is considered the gold standard for heritage retrofits precisely because it elegantly solves this problem. When paired with Low-E double glazing matched to original timber window profiles, you get thermal performance without compromising the home’s character from the street.
Moisture is another issue, as historical homes breathe (literally). Suspended timber floors depend on airflow through sub-floor voids to stay below the moisture threshold that triggers fungal decay. Block those voids with non-breathable insulation or an ill-considered slab, and you’ve traded a century-old floor for a structural repair bill. We use vapour-permeable membranes and materials like wood fibre or cellulose insulation that work with these buildings rather than against them.
Design-led building is the answer
The design phase isn’t just about pricing up a set of drawings. It’s about testing buildability in real time and identifying where a structural solution is unnecessarily expensive or where an alternative approach achieves the same architectural effect more efficiently. The design intent needs protection from the kinds of practical compromises that can quietly erode a project’s quality mid-build.
Our in-house carpentry team ticks this box. Those heritage junctions are where most renovations succeed or fail. Having direct control over the carpenters means these details get the precision they demand, every time.
Making heritage homes work for modern families
The design philosophy we apply to Surrey Hills homes is what we call a “proper transition.” The street-facing elevation and formal rooms are preserved (or restored) to their original standard. Leadlight windows, ornate cornices, fireplaces: these stay, and they’re treated with care.
Moving toward the rear, the architecture gradually opens up, typically through a glass link or visual break that satisfies council requirements while allowing northern light to penetrate deep into the original home.
At the back, modern family life gets what it needs: open-plan living that connects to an alfresco zone, a kitchen that actually functions at scale, storage that makes sports seasons survivable, and spaces designed to evolve, from children’s rumpus room to teenage retreat to multi-generational studio as the family changes over time.
Clerestory windows, rooflight scoops, and double-height gables bring light into spaces previously defined by darkness. Large sliding or stacking doors extend the home’s entertaining capacity into the garden, which in Melbourne’s variable climate is the difference between a house that works and one that doesn’t.
Surrey Hills home renovations you can count on
If you’re planning a significant renovation in Surrey Hills or the broader Boroondara area, the single most important thing you can do is start early. Ideally, three to six months before you want construction to begin, so the planning process can run its course, for the design to be properly tested, and for the kind of careful pre-construction thinking that prevents expensive problems mid-build.
At ELTCON, we work with homeowners at the early concept stage and alongside architects and designers throughout. If you’re working on a period property in the eastern corridor and you want a builder who understands both the history and the craft, we are it. Let’s have a chat about your ideas and make some plans (literally)!
