Renovations & additions
Reworking existing homes without losing what matters.
Adelaide's character is worth preserving. A renovation is often treated as the cheap way to change a house — we see it differently. There's real craft in renewing what's already there: it takes respect for the original, and the patience to recreate detail properly. And there's an art to reworking a home into a new format while building in high-performance principles — bringing modern thermal comfort and cleaner air to a house that predates both.
Why SV Built
Renovating is harder than building new. We've learned to lead with measurement, not assumption.
-
01
Character is the part you can't add back easily.
Original brickwork, ceiling roses, leadlight, the proportions of a room — these are why a character home is worth keeping. We work to retain and restore them rather than paper over them, so the home still reads as itself when we hand it back.
-
02
Renewing the old is real craftsmanship.
Matching a century-old cornice or rebuilding a bullnosed verandah properly takes patience and the right trades. We'd rather take the time to recreate a detail faithfully than replace it with something that only almost matches.
-
03
Comfort brought up to today's standard.
Behind the period detail we upgrade what you never see — insulation, airtightness, glazing and fresh-air ventilation — so an old house finally feels warm in winter, cool in summer and breathes cleanly. Where the home allows, we can take a renovation all the way to Passive House standard.
Ideal for
Owners of older Adelaide homes who want to modernise for comfort, space, functionality, performance and longevity — without tearing down what makes the home worth keeping.
FAQ
Renovation questions.
- Can an existing home be made high-performance?
- Often, yes. While an existing home rarely reaches full Passive House certification, a well-considered renovation can dramatically improve airtightness, insulation, glazing and ventilation — lifting comfort, lowering running costs and improving air quality. We assess what is realistic for your home and where the budget is best spent.
- Do you work on heritage or character homes?
- Yes. Adelaide has a lot of character housing, and we take a heritage-aware approach — retaining what matters while quietly upgrading the parts that affect comfort and health, so the home feels original but performs like a new one.
- Will a renovation actually improve comfort and air quality?
- When it addresses the building envelope and ventilation, yes — measurably. Sealing leaks, improving insulation and adding controlled fresh-air ventilation reduces draughts, condensation and mould risk and keeps temperatures more stable through the year.
