Melbourne’s period homes are loved for their character, but many were built for a very different way of living. When families outgrow a single-storey Victorian, Edwardian or Californian Bungalow, going up is often the smartest way to gain space – especially on tight inner-suburban blocks where the backyard is too precious to sacrifice.
A second-storey addition on a heritage home is a delicate exercise, though. Done well, it’s barely noticed from the street. Done poorly, it can overwhelm the original home and run into trouble with council. With four generations of building experience across Melbourne, here’s what Australian Heritage Homes has learned about going up gracefully.
Why Go Up Instead of Out?
- Keep your garden: on small blocks in suburbs like Northcote, Brunswick or Elwood, outdoor space is often limited.
- Separate zones: bedrooms upstairs, living downstairs – a layout many families prefer.
- Capture views and light: an upper level can access northern sun and outlooks a single storey can’t.
- Avoid relocating: stay in the suburb, school zone and community you love.
Sometimes a combination works best – a modest rear extension for open-plan living, with a compact upper level for bedrooms.
Understanding Heritage Overlays and Sightlines
Most councils with heritage overlays – Boroondara, Stonnington, Yarra, Glen Eira and Bayside among them – are less concerned about whether you add a second storey than about how visible it is from the street. Common expectations include:
- Setting the upper level well back from the front facade, often behind the main roof ridge
- Keeping the original front rooms and roof form intact
- Using recessive materials and colours so the addition doesn’t compete with the heritage home
- Demonstrating through sightline diagrams that the addition is concealed or minimised from the footpath opposite
Sightline studies are a crucial part of the planning permit application. We prepare these early in our design and build process so design decisions are grounded in what council is likely to support.
Structural Realities of Building on an Old Home
Period homes were rarely designed to carry a second storey. Original stumps, footings and wall framing usually need assessment by a structural engineer. Typical works include:
- Restumping or underpinning to carry new loads
- Steel beams or posts concealed within walls to transfer weight to new footings
- Upgrading or replacing roof framing where the addition connects
- Careful protection of the existing home during construction – ceilings, cornices and floors are vulnerable
This is where experience with older homes really matters. Our team understands how period construction behaves and how to integrate new structure without damaging original fabric.
Design Approaches That Work
There are two broad philosophies for heritage additions. The first is a sympathetic approach – using matching weatherboards, roof pitches and window proportions so the addition feels like part of the original. The second is a contrasting approach – a lightweight, contemporary form in materials like standing-seam metal or fibre-cement cladding that’s clearly new but deferential to the original.
Councils increasingly favour the second approach because it keeps the heritage home legible. Either way, proportions, setbacks and materials are what make the difference.
Comfort and Sustainability Upstairs
Upper levels can overheat in Melbourne summers if they aren’t designed carefully. Good eave overhangs, well-placed windows, high-performance glazing and generous insulation keep the new rooms comfortable. A second-storey addition is also a great opportunity to improve the whole home’s efficiency – read more about our sustainable home design approach.
Is a Second Storey Right for You?
Going up isn’t always the most cost-effective path. Where the existing home is in poor condition and not heritage-protected, a knock-down rebuild may deliver more for your budget. Where the home is protected or well loved, a carefully designed renovation and addition is often the ideal outcome.
