The Hills is a big-block part of Sydney, and that changes what a renovation can be. A four-bedroom project home in Kellyville or Beaumont Hills that felt generous in 1996 now has a poky galley kitchen walled off from a formal lounge nobody uses, builder-grade laminate everywhere, and an ensuite the size of a phone box. You rarely have to move house to fix that. There is almost always room to take out the walls, push the living space to the rear, add a storey, or put a secondary dwelling in the back yard — the sort of thing that simply isn’t on the table on a 4-metre Inner West frontage. That’s builder’s work: structural beams, footings, a The Hills Shire Council DA or a complying development certificate, and five or six trades turning up in the right order. We take it on as a single builder — carpentry, plumbing, electrical, tiling and painting coordinated under one contract, with one person you call about the whole job.
The other half of the Hills is the acreage. Out through Dural, Kenthurst, Glenorie, Annangrove and Galston the constraints are completely different: a BAL rating on bushfire-prone land dictates the glazing, decking, screening and cladding you’re allowed to build with, and plenty of rural-fringe lots are still on septic rather than town sewer, which limits where a new footprint can sit and changes how council assesses it. Mature trees on those blocks often carry vegetation controls too. None of it stops the job — it just needs to be in the quote on day one instead of arriving as a variation in week six. You get a fixed itemised price before we start and a realistic program, not an open-ended day rate that drifts.

Home renovations Hills District owners take on split along one line: whether the property is on sewer or not. Through Castle Hill, Baulkham Hills, Kellyville, Cherrybrook and Rouse Hill you are generally on services and the job behaves like any other suburban renovation. Out at Dural, Glenorie, Annangrove and Kenthurst the lots run to acreage and a good number are on a septic or aerated wastewater system, and that single fact reorders the whole project.
On an unsewered block the site plan comes before the floor plan. The tank and the effluent disposal area have to stay where they are and stay clear of the new work, so the buildable footprint is set by the wastewater system rather than by the block boundary. Adding bathrooms or a secondary dwelling can mean the existing system has to be upgraded, and that needs to be in the budget from day one rather than discovered at approval.
Bushfire is the second factor. The bushland fringes through Glenorie, Annangrove, Dural and the Hornsby edge carry Bushfire Attack Level ratings that dictate glazing, external cladding, decking, screening and subfloor sealing. A BAL 29 or BAL 40 specification costs materially more than the same room on an unrated block. Tree preservation is the third — a mature tree near the proposed footprint may need an arborist report and may simply have to be designed around.
The housing stock is the youngest of any region we work in. Much of the Hills went up through the 1980s, 1990s and 2000s as large brick-veneer project homes on generous blocks. They are structurally sound and rarely need rescuing, which changes the brief: home renovations Hills District clients ask for are usually about bringing a well-built but dated house up to current standard — opening up the kitchen and living areas, rebuilding bathrooms properly, and adding space rather than fixing decay.
Block size means a lot of the work here is additive. Ground-floor extensions, new living wings, second storeys and granny flats are all viable where they would not be on a smaller lot closer to the city, and a secondary dwelling can often be approved as complying development through a private certifier if the lot meets the criteria.
One builder, one contract. On a Hills job the coordination that earns its keep is around the wastewater and bushfire assessments and the arborist, because on acreage those three between them decide where the building can physically go.

On acreage the site investigations set the program: wastewater capacity, BAL rating and any arborist report have to be resolved before the footprint is fixed, and on an unsewered block that is the longest item in the schedule. On a serviced block through Castle Hill or Kellyville that step largely disappears and the job runs on conventional build time.
When you compare Hills quotes, check the wastewater line and the tree line. A quote that assumes the existing septic copes and no arborist report is needed will always look better than one that has priced an AWTS upgrade and a design change around a protected tree — and will always be the one that moves later.
A last practical note. Because most home renovations Hills District clients ask about add floor area rather than rearrange it, the first question worth answering is what the block will actually allow — setbacks, wastewater capacity, bushfire rating and any protected tree. We work that out at the site visit, free, before anyone pays for drawings.
Cost on home renovations hills district work is driven by scope and finishes more than anything else. Because Hills blocks are generous, more of our work here lands in the top band — extensions, second storeys and granny flats rather than reshuffling the inside of the existing walls. As a guide, Hills District projects usually sit in these bands:
| Scope of renovation | Typical Sydney range |
|---|---|
| Single-room or cosmetic refresh — kitchen or bathroom, new finishes | $15,000 – $40,000 |
| Multi-room renovation — several rooms, some layout and services changes | $40,000 – $120,000 |
| Full-home renovation, extension, second storey or granny flat — structural work, additions, whole-home finish | $120,000 – $400,000+ |
| Granny flat or secondary dwelling — on a qualifying lot | $120,000 – $180,000 |
| Ground-floor extension or new living wing — acreage and large lots | $180,000 – $400,000+ |
Ranges are indicative only and are not a quote for home renovations hills district work. Your figure depends on the factors below — you get a fixed itemised price after a free site visit.
In the Hills, far more often than not. The project-home estates through Kellyville, Beaumont Hills, Rouse Hill and Castle Hill sit on blocks deep enough to make a rear extension or a secondary dwelling genuinely viable, and the two-storey brick homes are usually built to carry an addition. What decides it is your lot size, setbacks, floor space ratio and the controls The Hills Shire Council applies to your street. We tell you what your block will actually carry at the site visit, before you spend a dollar on drawings.
No, but both need to be dealt with up front rather than discovered. A BAL rating on the Dural, Kenthurst, Glenorie or Galston fringe sets the construction standard — ember screening, the glazing you can use, the decking timber, how eaves and subfloors are sealed. Septic sets where the new footprint can go, because the tank and its disposal area have to be kept clear and council will look at it. We price both into the quote from day one.
Yes. Some renovations go through as complying development, others need a DA — and bushfire, vegetation or on-site wastewater controls can add requirements on top. We work with your architect or certifier and manage the build side of it so the approval doesn’t stall the program.
With a fixed itemised quote up front, and written variations if the scope changes — you approve any cost before it’s incurred. Nineties project homes throw up their own surprises: a load-bearing wall where the plans said stud, a slab that isn’t level, waffle-crete that complicates a rear opening. When that happens you hear about it in writing with a price attached, not at the end on the final bill.
No, but it constrains where you can build. On a septic or aerated wastewater system the tank and the effluent disposal area have to stay clear of the new work, so the site plan comes before the floor plan. Adding bathrooms or a second dwelling can mean the system needs upgrading, and that belongs in the budget from day one.
The construction specification. A Bushfire Attack Level rating sets requirements for glazing, cladding, decking, screening, subfloor and roof sealing, and the higher the BAL the more the materials cost. We establish the rating before quoting so the number you get is the real one.
Often yes — Hills lots are generally large enough, and a secondary dwelling can be approved as complying development through a private certifier where the lot meets the criteria. On an unsewered property allow for the wastewater system on top of the build cost. We check the lot against the criteria at the site visit rather than guessing.
On Hills acreage the gap is usually wastewater and trees. A quote priced without an AWTS upgrade or without allowing for a protected tree near the footprint will look cheaper than one that has accounted for both, and it is the second that survives contact with the certifier.
On 1980s and 1990s brick veneer it is less common than in older stock, but it happens — an unventilated wet area, a leaking shower base that has rotted the frame, or undersized electrical. We show you what we found, what it costs to fix and what happens if it is left, as a written variation you approve first.
It depends on scope, and Hills homes often have the advantage of a second bathroom to fall back on. A kitchen or a whole floor generally cannot be worked around, because water and power get isolated. We tell you at quoting stage which weeks are liveable and which are not, so you can plan rather than find out mid-job.
Yes. After a free site visit you get a fixed itemised quote for your home renovations Hills District project, broken down by trade and stage. If scope changes once work is under way it is written up as a variation with a cost and you approve it first.
The same five steps on every Hills District renovation, so you always know where the project and the budget stand.
We walk the whole project with you, measure up, look at what the block will carry and where the setbacks, trees and any bushfire or septic constraints sit, and talk through what you actually want changed.
A detailed written quote broken down by trade and stage — including BAL-rated materials, structural steel or wastewater work if your site needs them — so you can see exactly what you’re paying for.
We coordinate with your architect or certifier and manage the build side of The Hills Shire Council sign-off, whether that’s complying development or a full DA.
Every trade is scheduled and supervised by us under the one contract, and you have one person to call about progress at any time.
A final walk-through with you, a clean site, all certificates and warranties handed over, and a 10-year workmanship guarantee on the build. Every one of our home renovations hills district projects finishes this way, and if something needs attention later you call the same person who ran the job.
We renovate right across the Hills — Castle Hill, Baulkham Hills, Kellyville, North Kellyville, Bella Vista, Norwest, Beaumont Hills, Rouse Hill, Winston Hills, West Pennant Hills, Cherrybrook, Glenhaven, Dural, Kenthurst, Annangrove, Glenorie, Galston, Box Hill and the surrounding areas.
That is the most common job we are asked for in the Hills. Those floor plans separated the kitchen, meals and family areas into small walled rooms with a formal lounge and dining nobody has used in fifteen years. Opening them up means identifying what is load-bearing, putting a beam in, relocating the plumbing and power, and levelling floors where the old walls came out — then a new kitchen replacing the original builder-grade cabinetry, which is usually what prompted the call in the first place.
Yes, and they make up a large share of our Hills work, because the blocks are big enough to support them. Ground-floor and rear extensions, second-storey additions, granny flats and secondary dwellings on qualifying lots, and alfresco and outdoor-living additions — all under one contract with the same fixed itemised quote and 10-year guarantee.
Yes. A BAL rating doesn’t block the renovation — it sets the construction standard for glazing, ember screening, decking, cladding and how the roof and subfloor are sealed. It matters most on the acreage and bush-fringe blocks around Dural, Kenthurst, Glenorie, Annangrove and Galston. We build to the BAL your bushfire assessment specifies and price those materials into the quote up front.
A cosmetic single-room refresh is typically $15,000–$40,000, a multi-room renovation $40,000–$120,000, and a full-home renovation, extension or second storey $120,000–$400,000+. BAL-rated bushfire materials and on-site wastewater constraints push an acreage job toward the upper end of its band. You get a fixed itemised quote after a free site visit.
