About 5J Building Group

Home renovation in Glen Waverley by a registered local builder

Glen Waverley isn't new territory for us. 5J Building Group has completed projects right here and next door in Wheelers Hill, and we've been renovating Melbourne homes for more than two decades as a registered domestic builder, taking on everything from kitchens and bathrooms to extensions, granny flats and full rebuilds.

Much of Glen Waverley was built between the 1950s and 1970s, with homes constructed to a generally high standard on large blocks, often around 800 m². Those solid houses and generous gardens make excellent candidates for renovation, especially for families who want to stay close to Glen Waverley Secondary College, The Glen and the train line rather than start again somewhere else.

Whether it's modernising a 1970s kitchen and bathrooms, adding a rear family room or a second storey, or creating space for grandparents, we'll show you what your block allows and what each option costs. The site visit and quote are free, and you'll get weekly updates once work starts.

This was my first experience with 5J BUILDING GROUP. They basically did a complete home renovation for me - bathrooms, kitchen, flooring, and painting. This was done "remotely", because I was live in China, but they did what I asked them to do, and did a good job! I give them the highest possible rating!

About the area

Renovating in Glen Waverley

Glen Waverley sits about 19 km south-east of the Melbourne CBD in the City of Monash. Glen Waverley station is the terminus of its train line and a future Suburban Rail Loop interchange, and The Glen is one of Victoria's largest shopping centres.

The suburb's large post-war blocks are increasingly being subdivided, but many owners prefer to renovate and extend the family home. On blocks of this size, Victoria's garden area rule usually requires 35% of the lot to stay as garden, which shapes how big an extension can be.

Local planning

Planning and permits in Glen Waverley

Glen Waverley is in the City of Monash, so renovations are assessed under the Monash Planning Scheme and Victoria's building regulations. These are the controls we check most often before designing a Glen Waverley renovation.

Check your zone and overlays

Your zone and any overlays decide which rules apply. You can check them on Monash Council's online mapping tool or on VicPlan, including whether your property has a Vegetation Protection Overlay. 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. Structural work also needs a building permit from a registered building surveyor, which we arrange.

Large blocks and garden area

On a typical 800 m² Glen Waverley block, Victoria's garden area rule requires 35% of the lot to stay as garden (30% for 500–650 m², 25% for 400–500 m²). In the Neighbourhood Residential Zone, homes are generally limited to 9 m and two storeys. We factor both in before designing an extension.

Monash's tree controls

In Monash's residential zones, a planning permit is needed to remove or lop a canopy tree over 5 m tall with a 4 m canopy and a trunk circumference over 0.5 m, within 6 m of the front boundary or 4.5 m of the rear. Where a Vegetation Protection Overlay applies, trees over 10 m tall with a trunk circumference over 50 cm (at 1.2 m) are also protected. Dead trees are exempt.

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

Glen Waverley renovation FAQs

Do I need a permit to renovate my home in Glen Waverley?

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. Structural work also needs a building permit. We check your property's zone and overlays early and manage the permits as part of the job.

Should I renovate or knock down and rebuild in Glen Waverley?

It depends on the condition of the house and what you need. Many of Glen Waverley's 1950s–70s homes are well built and suit a renovation and extension, while others are better replaced. We can price both options after an on-site visit so you can compare cost, time and outcome before deciding.

Do I need a permit to remove a tree before renovating in Glen Waverley?

Sometimes. In Monash, a planning permit is needed to remove or lop a larger canopy tree near your front or rear boundary, and properties in a Vegetation Protection Overlay have extra controls. Dead trees are exempt. We check your trees at the design stage and build any permit into your timeline.

How much does a renovation in Glen Waverley 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.

Do you also renovate in suburbs near Glen Waverley?

Yes. We renovate across Monash and the surrounding suburbs, including Mount Waverley, Wheelers Hill, Notting Hill and Ashwood. You get the same team, the same trades and the same free on-site quote wherever you are.
