About 5J Building Group
Home renovation in Sandringham by a registered local builder
Bayside renovations are a regular part of our work, with recent projects in Hampton, Brighton and Mentone. 5J Building Group is a registered domestic builder with more than 20 years of experience, taking on extensions, kitchens, bathrooms, whole-home renovations and rebuilds.
Sandringham has a relaxed village feel, with period buildings including the railway station, a walkable shopping precinct of cafés and boutiques, and Port Phillip Bay at the end of the street. Its origins go back to 1852, and many of its homes are established houses on streets close to the beach, where owners want more space, better light and a stronger connection to outdoor living.
Whether you're extending a family home, reworking a kitchen and bathrooms or planning a complete bayside renovation, we specify materials that stand up to coastal conditions and check Bayside's heritage and tree controls early. Book a free visit for an detailed quote.

About the area
Renovating in Sandringham
Sandringham sits about 16 km south of the Melbourne CBD in Bayside, at the end of the Sandringham line, which reaches the city in about 27 minutes. The foreshore, Trevor Barker Oval and the village shops are all close to home.
Like much of Bayside, Sandringham's character comes from its established homes and mature trees. Bayside's local law protects large trees, and some areas have a Vegetation Protection Overlay, so it's worth checking your block before planning an extension.

Local planning
Planning and permits in Sandringham
Sandringham is in the Bayside City Council, so renovations are assessed under the Bayside Planning Scheme and Victoria's building regulations. These are the controls we check most often before designing a Sandringham renovation.
Check your zone and overlays
Your zone and any overlays decide which rules apply. Bayside Council points homeowners to its online planning maps, and to the Heritage Overlay schedule in the Bayside Planning Scheme for heritage places. We check this before design starts.
When an extension needs a permit
Under the standard residential zone rules, extending a single house often doesn't need a planning permit unless the lot is under 300 m² or an overlay applies, such as a Heritage Overlay or Vegetation Protection Overlay. Structural work also needs a building permit from a registered building surveyor, which we arrange.
Heritage and native vegetation
If your home is in a Heritage Overlay, Bayside requires a planning permit for demolition, and extensions, alterations and fences should be sympathetic to the valued heritage elements. In the Vegetation Protection Overlay (VPO3) area, removing native vegetation over 2 m high with a trunk circumference over 0.5 m also needs a permit.
Bayside's tree rules
Bayside's local law protects trees with a single or combined trunk circumference over 155 cm measured 1 m above ground. In the Vegetation Protection Overlay (VPO3) area, a permit is also needed to remove native vegetation over 2 m high with a trunk circumference over 0.5 m at 1 m. Qualified arborists can prune protected trees to the Australian Standard without a permit.
Planning rules change and every property is different, so treat this as a general guide rather than planning advice. We confirm the controls for your address as part of your free quote.
FAQs
Sandringham renovation FAQs
Do I need a permit to renovate my home in Sandringham?
It depends on the work and your property. Extending a house usually only needs a planning permit if the lot is under 300 m² or an overlay applies, such as a Heritage Overlay or Vegetation Protection Overlay. Structural work also needs a building permit. We check your property's controls early and manage the permits as part of the job.
Do bayside conditions affect how you build in Sandringham?
They affect material choices. Close to the bay, salt air is harder on metals, finishes and outdoor fixtures, so we specify durable, corrosion-resistant products for exposed areas. We also check your property's heritage and vegetation controls before design so the plan suits both the site and the rules.
Do I need a permit to remove a tree before renovating in Sandringham?
Often, yes. Bayside's local law protects trees with a trunk circumference over 155 cm measured 1 m above ground, and the Vegetation Protection Overlay (VPO3) protects native vegetation over 2 m high in some areas. We check your trees at the design stage and build any permit into your timeline.
How much does a renovation in Sandringham cost?
Every home is different, so we quote each job individually after an on-site visit. As a general guide, many homeowners aim to spend around 5–10% of their property's value on a renovation. Our quotes are free, tailored to your budget and have no hidden costs.
How long does a home renovation take?
It depends on the scope. A kitchen and two bathrooms typically take 4–8 weeks, larger renovations usually take 2–4 months, and extensions or new builds can take up to 10 months. We give you a clear timeline with your quote.
