Central Coast Builders and Electricians, Under One Roof
Belvedere Building & Electrical is a family business of Central Coast builders and electricians. Brothers Vincent Quin, a licensed builder, and Clarence Quin, a licensed electrician, build new homes, renovate kitchens and bathrooms, add decks and upgrade switchboards from Gosford to Newcastle and the Hunter, with both trades working from one program and one quote.

Who we are
What does Belvedere Building & Electrical do?
We are a licensed builder and a licensed electrician running one company, so a single team handles the structure, the finishes and the wiring of your project.
Vincent Quin is the licensed builder (NSW Fair Trading licence 329 075C) and leads the building side: new homes, knockdown rebuilds, granny flats, extensions and renovations. Clarence Quin runs the electrical side, from rough-in and fit-off on our own builds to switchboard upgrades, lighting, solar connections and fault finding for homes and businesses. Between them they bring more than a decade of hands-on work across high-end homes, renovations, property development and electrical jobs.
The benefit shows up on site. Your electrician is not a subcontractor squeezed into another builder's week; he is the co-director who helped price the job. Power point positions, switchboard capacity and lighting plans get settled while the frame is going up, not after the plasterboard is on. You also get one contract, one payment schedule and one phone number from the first site visit to handover.
The same approach carries into property development, where we take a site from acquisition and approvals through construction management to handover. At the other end of the scale, we are just as happy to fit a single power point or rehang a sticking door.

Services
Which building, renovation and electrical services do we offer?
Four groups of work, all priced and managed by the same two directors. Pick the one closest to your project. Each link opens a page covering scope, process and the questions worth asking before you sign anything.
Led by VincentNew homes and building
Custom and luxury homes, knockdown rebuilds, duplexes and granny flats, built to the National Construction Code with a Principal Certifier inspecting each stage. We prepare the engineering, BASIX and approval documents with your certifier, so you deal with one builder from slab to keys.
Builder Central Coast services
Led by VincentRenovations and extensions
Kitchens, bathrooms, laundries and whole-home renovations, plus extensions and garage conversions that add a bedroom without moving house. Because Clarence rewires as the walls open up, older homes with tired switchboards or no safety switches are brought up to standard in the same job rather than a second project later.
Renovation Central Coast services
Led by ClarenceElectrical services
Licensed electrical work for homes and small commercial sites: switchboard upgrades, safety switches, LED lighting, solar connections, smoke alarms, data points and fault finding. Small jobs are welcome, and anything that needs certifying is tested and signed off with the compliance paperwork lodged in your name.
Electrician Central Coast services
Led by VincentDecks, pergolas and pools
Hardwood and composite decks, gable and flat pergolas, alfresco rooms and pools, with lighting, fans and outdoor power designed in from the start. Coastal sites need stainless or hot-dip galvanised fixings and good drainage under the boards, and we detail both before the first post goes in.
Deck builders Central CoastOne team, two trades
Why does having the builder and electrician in one company save time?
Most delays on a build happen at hand-offs, when one trade waits for another. On our jobs both lanes run from the same program, so those gaps close up. This is how the two trades move through a typical new home or major renovation.
- Building lane, led by Vincent
- Electrical lane, led by Clarence
- One shared program
-
01
Plan and approve
Before site worksBuildingScope, drawings, engineering and BASIX lined up with your certifier. One itemised price covers both trades.ElectricalLoad and board capacity checked against the plans, including solar, an EV charger or pool gear you want now or later. -
02
Slab and ground
Set-out to pourBuildingSet-out, excavation, steel and pour, with the certifier inspecting the reinforcement before any concrete arrives.ElectricalConduits and the underground supply placed before the pour, so nobody has to cut the new slab later. -
03
Frame and roof
Structure upBuildingTimber frame to Australian Standards, roof on and windows in, then the frame inspection is booked.ElectricalA walk-through with you on the real frame to fix power points, switch heights and every light position. -
04
Rough-in and close
Walls closedBuildingInsulation to BASIX, then plasterboard, but only once the electrical rough-in has been checked off.ElectricalCabling, data and downlight positions roughed in the same week the frame passes its inspection. -
05
Wet areas and fit-off
FinishesBuildingWet areas waterproofed and inspected, then joinery, tiling, stone benchtops and paint.ElectricalSwitches, lights, fans, appliances and the switchboard fitted off, followed by full testing. -
06
Handover
Keys and paperworkBuildingFinal certifier inspection, a defects walk-through with you and a complete handover pack.ElectricalCompliance certificate lodged, plus a labelled board schedule so you know what every circuit runs.
On a job split between separate companies, stages 3 and 4 are where weeks disappear. The frame passes, the builder rings the electrician, and the electrician has other clients that week. On ours, Clarence already knows the inspection date because it is on the same program he helped write. That alone removes one of the most common waiting periods on a residential build.
Clashes get settled faster too. A downlight that lands under a beam or a power point hidden behind new joinery is a five-minute conversation between two directors on site, not a variation, a second quote and a debate about who pays. Years later, the person who wired your house is still the person who answers when you want another circuit added.
| Question | Separate builder and electrician | Belvedere, one company |
|---|---|---|
| Who books the rough-in? | The builder rings a subcontractor and waits for a free day | Booked on the shared program before the frame is inspected |
| Who fixes a clash? | Two parties, two opinions, often a variation | Settled on site by the two directors |
| How many quotes and contracts? | Usually two or more | One itemised quote, one contract |
| Who lodges the electrical certificate? | The subcontractor, sometimes chased after handover | Lodged by us before the keys are handed over |
| Who do you call after handover? | It depends on what has gone wrong | One number, structural or electrical |
Project spotlight
What did we build at 39 Wandella Avenue, Bateau Bay?
An architecturally designed, two-storey family home in East Bateau Bay, around 700 metres from the beach. We built it from the slab to the landscaping, with the pool and every circuit handled by our own team.

When should you call a Central Coast electrician?
Call a licensed electrician whenever something trips, sparks, smells hot or stops working, and before you add a big new load such as air conditioning, solar, a pool pump or an EV charger.
Clarence handles everything from a single extractor fan to a full rewire. Plenty of older Central Coast homes still run on rewireable ceramic fuses with one safety switch, or none at all. Those boards were never designed for modern appliances, and adding load to them is where faults begin. Signs worth acting on:
- Pull-out ceramic fuses, or a board with no safety switches (RCDs)
- Breakers that trip often, or lights that dim when the kettle goes on
- A burning smell, warmth or scorch marks near the board or a power point
- Plans for solar, a battery, an EV charger, ducted air or a pool
- Buying or leasing out an older home and wanting a proper safety inspection
Every job that needs one ends with a Certificate of Compliance for Electrical Work (CCEW), which must be lodged with Building Commission NSW within seven days of testing under the NSW electrical compliance requirements. Work on the network connection itself, such as service mains and overhead or underground connections, sits under the NSW Accredited Service Provider scheme, and our Level 2 page explains when that applies. We also fit and replace interconnected smoke alarms, and upgrading an older board in a typical house is usually finished within a working day.
Old board versus new board
A new board swaps pull-out fuses for circuit breakers, puts every final circuit behind a safety switch and leaves spare space for solar, a battery or an EV charger later.
When Clarence looked at the issue he realised that the meter board was dangerously outdated, he spent many hours fixing the problem and checking every power point in the house.
Approvals and paperwork
What approvals and paperwork should a NSW homeowner expect?
It depends on the project. Use this table as a starting point, then confirm the pathway for your own block with us or your certifier before you commit to a design.
| Project | Usual approval pathway | Paperwork you should receive |
|---|---|---|
| Deck or pergola | Often exempt development if it meets the State limits, which for a deck generally means no more than 25 m² and no higher than 1 m above ground, plus setbacks. Otherwise a CDC or DA. See the Planning Portal exempt development guide and our deck approval guide. | A written contract for work over $5,000, and an HBC certificate if the job is over $20,000 |
| Granny flat | Complying development is possible on many residential lots of 450 m² or more for a secondary dwelling up to 60 m². Smaller or constrained lots usually need a DA. See the NSW secondary dwelling rules. | Contract, HBC certificate, BASIX certificate and an occupation certificate |
| Kitchen or bathroom | Usually no council approval when the work is internal and non-structural | Contract over $5,000, a waterproofing certificate for wet areas, and a CCEW for any electrical work |
| Extension or second storey | CDC or DA, with structural engineering | Contract, HBC certificate, engineering certificates and an occupation certificate |
| New home or knockdown rebuild | CDC or DA | Contract, HBC and BASIX certificates at the start, then an occupation certificate before you move in |
| Switchboard upgrade or rewire | No council approval | A CCEW lodged within seven days of testing, plus Level 2 paperwork if the service connection changes (meter changes go through your electricity retailer) |
Licence and contract
Residential building work over $5,000 needs a licensed contractor and a written contract. Search any licence on the NSW licence register.
Deposit cap
A builder cannot ask for a deposit above 10% of the contract price. Ours sits inside that limit, and later payments follow finished stages. See the NSW contract rules.
HBC cover
Jobs over $20,000 need home building compensation cover, and you should see the certificate before paying anything. Read the insurance requirements.
Electrical certificate
Electricians must lodge a CCEW within a week of testing their work. Ask for your copy at handover and keep it with your house records.
A Principal Certifier, either from council or a registered private certifier, is appointed before work starts on any CDC or DA job. The owner makes that appointment, not the builder. The certifier inspects set stages such as footings, frame, wet areas and the final, then issues the occupation certificate. We book those inspections around the program so the job never sits waiting. See appointing a certifier in NSW.
Local conditions
What should you plan for when building on the coast or in the Hunter?
Each region we cover has its own site conditions, and every one of them changes the design and the price. These are the six we check before quoting, so none of them surfaces halfway through a job.
Salt air and corrosion
Homes close to breaking surf, around Terrigal, Wamberal and Bateau Bay, need marine-rated roofing, 316 stainless or hot-dip galvanised fixings and coatings suited to the exposure. Standard zinc-plated fixings rust quickly in salt air, so we specify them by the site rather than by habit.
Bushfire attack level
Large parts of the Central Coast and the Hunter are mapped as bush fire prone land. If yours is, a Bushfire Attack Level (BAL) assessment under AS 3959 sets the rules for windows, gutters, sarking and decking boards, and a higher BAL narrows the timbers a deck can use. Check your block through the NSW Rural Fire Service.
Flooding and acid sulfate soils
Around Tuggerah Lake and other low-lying land, council mapping can set minimum floor levels, and some soils turn acidic once they are dug up and exposed to air. Both affect slab height, excavation and how spoil is handled, so we read the planning certificate before pricing any earthworks.
Mine subsidence districts
Parts of Newcastle, Lake Macquarie, Maitland, Cessnock and the Upper Hunter sit above old coal workings. Building inside a mine subsidence district needs approval from Subsidence Advisory NSW, which can set conditions on footing design and the size and type of structure.
Reactive clay soils
Many Hunter suburbs sit on clay that swells when wet and shrinks when dry. A geotechnical report classifies the site under AS 2870, from class A for stable sand and rock up to class E for extremely reactive clay, and that class decides slab thickness, beam depth and how far down the footings go.
Termite management
New homes in NSW need a termite management system that meets AS 3660.1, usually a physical barrier at slab level plus a visible inspection zone around the edge. On renovations we check for past damage whenever old timber is opened up, and repair it before any new work is fixed to it.
How we work
How do we quote and run a job from first call to handover?
Five steps, the same on a small electrical job as on a new home, just scaled to fit. Nothing starts on site until you hold the price, the contract and, where needed, the approvals.
- 01
Site visit
Vincent, Clarence or both come out, measure up and talk through what you want, what the site allows and a realistic budget range.
- 02
Itemised quote
A written price that separates building and electrical lines, with every allowance listed rather than buried in a lump sum.
- 03
Contract and approvals
The right contract for the job size, a deposit inside the 10% cap, HBC cover where needed and approvals lodged with your certifier.
- 04
Build and inspect
Staged works with certifier inspections at slab, frame and wet areas, and regular updates so you know what is happening between site meetings.
- 05
Handover
A walk-through, a defects list closed out, and every certificate, warranty and appliance manual collected in one pack.
The team
Who will actually be working on your home?
You deal with the directors, not a sales team. Vincent and Clarence quote the work, run the site and answer the phone, supported by their own crew and licensed local trades.
Vincent Quin
Director and BuilderVincent holds NSW Builder Licence 329 075C and has spent more than a decade in residential construction, from architect-designed homes like Wandella Avenue to renovations and development sites. He plans the program, manages the trades and meets the certifier on building jobs.
Clarence Quin
Director and ElectricianClarence is a licensed electrician with a builder's eye for how services fit into a structure. Reviewers mention how clearly he explains a fault and how clean he leaves a site. He designs, installs, tests and certifies the electrical side of every Belvedere job.
The site crew
Carpentry and site worksOur crew on site in their Belvedere shirts. Alongside them we bring in licensed local trades for plumbing, waterproofing, tiling and concrete, choosing people we have worked with before so standards hold from one project to the next.
Client reviews
What do clients say about working with us?
Every review below is quoted from Google as the client wrote it. The common threads are turning up when promised, explaining the work clearly and leaving the site clean.
Excellent, based on 17 Google reviews
Clarence installed a new bathroom extractor fan at short notice. He did an excellent job. Fast. Efficient and excellent to deal with.
Minutes after a hipages ad I was contacted & the automatic gate repair work was done same day. On time & under budget.
Clarence and Vincent completed our back deck including electrical work. They were very efficient and had high attention to detail.
Vincent recently completed some renovation works at our house and I would highly recommend him and his team. His workmanship was excellent.
He handled the electrical work efficiently, explained everything clearly, and made sure the site was left clean and safe.
Top quality work from top quality people, great communication, knowledge and efficiency. Definitely recommend for all building related works.
Service areas
Where do our Central Coast builders and electricians work?
Across three regions: the Central Coast, Newcastle and the Hunter. Choose your suburb or town below to open its local page, or ask us about a site nearby that is not listed. If your project is further afield, ask anyway: we have travelled as far as Condobolin and Warren for the right job.
M1The Pacific Motorway ties the three regions together, which is why one team can look after a Terrigal renovation, a Newcastle switchboard and a Maitland new build in the same month.
Central Coast
Coastal homes where salt air, sandy soil and steep blocks all shape the build, from the Gosford waterfront to the beach suburbs.
Newcastle
Character homes that need careful renovation, older wiring that needs replacing, and new builds on tight city lots.
Hunter Region
Bigger blocks, rural builds and growing estates through Maitland, the vineyards and the Upper Hunter. See our Hunter Valley builders page.

Plan your buildFAQ
What do homeowners ask us most often?
Straight answers to the questions that come up at almost every first site visit.
Are you licensed and insured?
Yes. Our builder licence number is 329 075C, issued by NSW Fair Trading, and you can look it up on the NSW licence check, and all electrical work is carried out by a licensed electrician. We are fully insured, and for residential jobs over $20,000 we provide a home building compensation certificate before you pay anything.
Which areas do you service?
We work across the Central Coast, including Gosford, Erina, Terrigal, Bateau Bay and Long Jetty, plus Newcastle and the Hunter Region, including Maitland, Cessnock, Singleton and Muswellbrook. We have also completed renovations further west in Condobolin and Warren. If you are unsure, send us your address and we will tell you straight away.
Can one company really handle both the building and the electrical work?
Yes, and that is the whole idea behind Belvedere. Vincent is the licensed builder and Clarence is the licensed electrician, so one quote and one program cover both trades. It removes the wait between the frame inspection and the electrical rough-in, and one team is accountable for the finished result.
Do you handle council approvals and certification?
Yes. We prepare and coordinate the documents your approval needs, including drawings, engineering and BASIX where required, and work with a Principal Certifier or council through each inspection stage. Some small decks and pergolas can be exempt, and we will tell you honestly whether yours is.
How much deposit do you ask for?
Never more than 10% of the contract price, which is the maximum allowed for residential building work in NSW. After that you pay progress claims tied to completed stages, such as slab, frame, lock-up and fixing, so your money always follows finished work.
Do you take on property development projects?
Yes. Property development sits in our logo for a reason. We can help from site acquisition and feasibility through design, approvals and construction management to handover, whether the project is a duplex, a knockdown rebuild for resale or a single spec home.
Do you take on small jobs and emergency electrical call-outs?
Yes. Clients have booked us for a single bathroom extractor fan and for a same-day gate repair. For urgent faults see our emergency electrician page, and for small building repairs such as a sagging door or a rotten deck board, call and describe the problem.
How long does a switchboard upgrade take?
For a typical house, a straightforward board replacement usually takes most of a working day, with the power off for part of it. Older homes sometimes need extra circuits, earthing repairs or a new main switch, and we quote those before starting. You receive a CCEW once testing is complete.
Can you build a granny flat on my block?
Often, yes. In NSW a secondary dwelling of up to 60 square metres can be approved as complying development on many residential lots of 450 square metres or more, while lots under that size, or with heritage, flood or bushfire constraints, generally go through a DA instead. Our granny flat guide for Newcastle and the Hunter covers the details, and we can check your block on a site visit.
Do you work from an architect's plans or help with design?
Both. We build from architect and draftsperson plans, as we did at Wandella Avenue, and we can bring in a designer for a new project. Our value-engineering review often finds savings in structure or finishes without changing how the home looks or works.
How do I get a quote?
Call 0435 726 524, email Vincent@BelvedereBuild.com or use the contact form. We will book a site visit, usually with the director who will run the work, then follow up with a written, itemised quote. Office hours are Monday to Friday, 7am to 4pm.
What warranty comes with your building work?
Residential building work in NSW carries statutory warranties under the Home Building Act: six years for major defects and two years for all other defects, running from completion. Those rights sit on top of manufacturer warranties for products such as appliances, tapware and roofing, which we hand over in your completion pack.
