Boronia is exactly the kind of suburb where builder-led planning matters. It has a strong mix of established 1960s to 1980s weatherboard and brick-veneer homes, family blocks with room to extend, and foothill pockets where slope, drainage, and bushfire considerations can affect what is practical to build. From NPR Building Concepts’ base in Kilsyth, Boronia is only a short drive away—around 6 kilometres or 9 minutes—so you’ll be working with a nearby family-owned builder that knows how eastern suburbs projects actually come together.
NPR Building Concepts has more than 25 years of building experience throughout eastern Melbourne. We lead a family-run business focused on fixed-price contracts, zero hidden fees, and clear advice before you commit to expensive design work. If your project sits within Knox City Council, we’ll help you understand likely council and permit considerations early, not after you’ve already paid for plans that may not suit your site, budget or home.
If you’re considering an extension, renovation, second storey, or custom new build in Boronia, start with a practical roadmap rather than guesswork.

Start With The Right Planning Team For Your Project
In Boronia, the best outcomes come from getting your planning team aligned early. Architects, designers, and builders all add value. The important part is making sure design ideas are tested against real site constraints, council requirements, and budget from the beginning.
Many local projects involve older brick veneer or weatherboard homes, sloping blocks, and occasional bushfire-related considerations near foothill areas. If those practical factors are not reviewed early, projects can slow down once permits, engineering, or pricing are underway.
Our builder-led Step 1 Feasibility Study gives you that early clarity. For $3,500, we assess your site, provide concept direction and 3D visuals, and map out likely costs and next steps. This helps you make informed decisions with confidence before committing to full documentation.
If you already have an architect or designer, that is completely fine. We are happy to collaborate so your design intent, budget, and construction pathway stay aligned from day one.
SCHEDULE AN APPOINTMENTBuilding in Boronia
Boronia is within the City of Knox, approximately 30 kilometres east of the Melbourne CBD and only 6 kilometres from our Kilsyth base. The suburb is known for established family housing, a leafy foothill setting, and easy access to local amenities like Boronia Junction, Boronia Station, and Chandler Park. That combination makes it popular with families who want more room without leaving the area.
Common projects in Boronia include rear extensions, open-plan renovations, second-storey additions and knockdown rebuilds on older housing stock. Many homes date from the post-war period through the 1970s, which means they often need layout improvement, better indoor-outdoor flow, energy upgrades, and structural review before major works begin. Some parts of Boronia also require extra attention regarding sloping land, stormwater, vegetation constraints, and bushfire-related requirements due to the suburb’s proximity to the Dandenong Ranges foothills.
Permit timing through Knox City Council depends on whether your project needs planning approval, building approval only, or supporting consultant reports. That is exactly where local experience helps. We assess the property first, identify likely issues early, and provide you with a realistic path forward rather than vague estimates.

Custom New Builds
If your Boronia block is better suited to a fresh start, we design and build custom homes that respond to the site, streetscape and the way your family actually lives. That is especially useful on older blocks where the existing house no longer makes financial or practical sense to retain.
Home Extensions
Boronia is ideal for extensions because many homes sit on usable family blocks but have dated floorplans. We help you add space with fixed-price clarity and early advice on feasibility, the council pathway, and the likely construction scope.
Major Renovations
For homeowners who want to stay in Boronia but improve how their home works, we manage major renovations that open up living zones, upgrade kitchens and wet areas, and bring older homes into line with modern family needs.
Second Storey Additions
A second storey can make sense in Boronia, where land is limited, or you want to keep yard space. We assess structural suitability early so you know whether your existing home is a realistic candidate before you spend heavily on drawings.
How We Work
- Initial Call – Start with a free 15-minute discovery call. We’ll discuss your Boronia property, your goals, likely budget range and whether the project is worth exploring further.
- Step 1 Site Visit – Nicholas Ralph visits your property, reviews the home and block, and talks through your vision, constraints and priorities.
- Feasibility Package Delivered – Step 1 Feasibility Study: $3,500 (includes site visit, concepts, 3D renders, cost estimate). You’ll also receive a breakdown of likely engineering, permits, energy rating requirements and the next steps needed to move forward.
- Review Meeting – We present the feasibility study in person so you can understand the concept, the likely costs and whether the project still makes sense before committing further.
- Move to Detailed Design – If you want to proceed, we will move into working drawings, documentation and a detailed fixed-price quote based on a buildable scope.
Frequently Asked Questions
What’s included in your Step 1 Feasibility Study?
The Step 1 Feasibility Study costs $3,500 and includes Nicholas Ralph’s site visit, a property assessment, concept drawings, 3D renders, a practical cost estimate, and a breakdown of what is required to move into engineering, permits and detailed design. It is designed to help you make a smart decision before spending much more.
Do you offer fixed-price contracts?
Yes. Once the project scope and documentation are clearly defined, we work under fixed-price contracts with no hidden fees. That gives you far more certainty than vague allowances and moving targets.
How long does a typical extension take in Boronia?
Build time depends on size, complexity, access and permit pathway, but substantial extensions usually take several months once approvals are complete. The biggest timeline risk is often poor early planning, which is why feasibility comes first.
What’s the cost per square metre for extensions in Boronia?
There is no honest flat rate that suits every extension. Costs vary based on structure, finishes, access, site conditions, and the extent of rework required to the existing house. We give you a project-specific estimate during feasibility, so you’re working from real numbers, not generic averages.
Do I need to hire an architect before contacting you?
No. In most cases, you should speak with a builder first. That helps you avoid spending $8,000 to $15,000 on plans that may not suit your block, budget or council pathway.
What’s your service area from Kilsyth?
We generally work across Melbourne’s eastern suburbs within a roughly 45-minute drive radius. Boronia is well within our normal service area.
Do you offer a satisfaction guarantee?
Yes. We offer a 100% satisfaction guarantee, alongside dedicated aftercare support and transparent communication throughout the project.
How long do Knox City Council permits take?
It depends on whether your project needs planning permission, building approval only, or extra consultant input. Straightforward projects move faster than sites with overlays, slope issues or more complex design requirements. We identify the likely pathway early, so you have a realistic expectation.
Can I add a second storey to my 1960s or 1970s home in Boronia?
Sometimes, yes, but not every older Boronia home is a good candidate. The existing structure, footing capacity, layout and site constraints all need to be assessed first. That is one of the key reasons to start with builder-led feasibility.
Do I need a bushfire assessment in Boronia?
Some Boronia properties, especially those closer to the Dandenong Ranges foothills, reserves or bush-adjacent areas, may need bushfire-related assessment or BAL consideration. We review this early so you know whether it will affect the design, materials, or approvals.
What are the common challenges of extending homes in Boronia?
The most common issues are outdated layouts, structural limitations in older homes, sloping blocks in some pockets, drainage, and making sure the design actually suits the site and likely council expectations. None of that is unusual, but it does need to be assessed properly from the start.
