About 5J Building Group
We've already renovated in Hampton, as well as in neighbouring Brighton and nearby Mentone, so we know the bayside well. 5J Building Group is a registered domestic builder with more than 20 years of experience, specialising in extensions, kitchens, bathrooms, whole-home renovations and knockdown rebuilds.
Hampton grew from 1840s market gardens into one of Melbourne's favourite bayside suburbs, with Hampton Street's cafés and boutiques, the Sandringham line and the foreshore at Picnic Point all close by. Its streets include homes built for returned First World War soldiers, and many of Hampton's established houses are now ready for more space and a better connection to the garden.
Whether you're extending a character home, updating a kitchen and bathrooms or planning a full bayside renovation, we check Bayside's heritage and vegetation controls early and manage every trade on site. It all begins with a free, detailed quote at your home.

About the area
Hampton sits about 14 km south-east of the Melbourne CBD in Bayside, between Brighton and Sandringham. Hampton station on the Sandringham line and more than 50 cafés and restaurants along Hampton Street make it one of the most liveable parts of the bayside strip.
Established homes, heritage places and mature gardens are a big part of Hampton's character. For renovators, that means checking Bayside's Heritage Overlay and tree controls early and designing extensions that suit the streetscape.

Local planning
Hampton 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 Hampton renovation.
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.
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.
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. External paint controls apply only to some properties, and internal changes usually don't need a permit unless the property has internal controls.
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.
