A full home renovation runs in stages. Understanding what happens at each stage — and what drives the length of each — prevents the most common planning mistakes Perth homeowners make
Stage | Typical Duration | Typical Duration |
1. Free in-home consultation | 1–2 hours | House & Co visits your home. We assess the property age and condition, check likely hidden works (asbestos, plumbing, electrical), listen to the brief, and measure every room. No obligation, no cost. |
2. 3D design and scope development | 2–4 weeks | Every room is designed in 3D. Kitchen cabinetry, bathroom tiles, flooring, exterior palette — all modelled before any trade is booked. Revisions included until you're happy. This stage is where all material and finish decisions are made. Changes here cost nothing. Changes during construction cost significantly more |
3. Design approval and quote sign-off | 1 day – 2 weeks | You review the 3D design and fixed-scope quote. The faster decisions are confirmed at this stage, the sooner the build can be locked in. In Perth's 2026 trade market, key trades book 10–16 weeks ahead — design approval unlocks the schedule. |
4. Permits (if required) | 4–10 weeks | Wall removal, alfresco structural additions, and new wet areas require building permits in WA. House & Co manages the permit application. Permit timing runs in parallel with trade scheduling where possible — it should not add to the total project duration if planned correctly. |
5. Trade booking and scheduling | 4–8 weeks ahead | In Perth's 2026 market, quality licensed trades book 10–16 weeks ahead. The project schedule is built around trade availability and cabinetry manufacture lead times. A bathroom renovation starting the same week as a kitchen renovation in the same house requires careful sequencing. |
6. Site clearance and demolition | 1–2 weeks | 6. Site clearance and demolition 1–2 weeks Full strip-out of all rooms in scope simultaneously. Hidden works are identified here. Any discovered asbestos, galvanised pipes, or non-compliant electrical is addressed in this stage before construction begins. This is why pre-quote property assessment matters. |
7. Structural work | 1–3 weeks | Wall removal, new openings, lintels, beam installation. All structural work inspected before wall sheeting proceeds. If skylight installation is in scope, this is when roof penetrations are made. |
8. Rough-in services (all rooms) | 1–2 weeks | Plumbing rough-in and electrical rough-in across all rooms simultaneously while walls are open. This is the most efficient phase in a full home renovation — all trades are in the building at the same time. Cannot happen after wall sheeting. |
9. Wall sheeting, plastering, and waterproofing | 2–3 weeks | Walls closed in. Plaster set. Waterproofing in all wet areas applied, inspected, and approved before tiling. The waterproofing inspection is a mandatory hold point — tiling does not start until it passes. |
10. Tiling — all wet areas | 1–3 weeks | Bathroom, ensuite, and laundry tiling. Floor tile in kitchen if in scope. Tiling must be complete before cabinetry is installed. |
11. Cabinetry installation (all rooms) | 1–2 weeks on site (4–6 weeks manufacture) | Kitchen, bathroom, laundry, and wardrobe cabinetry all delivered and installed in sequence. CRITICAL PATH: custom cabinetry manufacture takes 4–6 weeks from design approval. This lead time is why the schedule is built around the cabinet delivery date, not the other way around. |
12. Benchtop template and fabrication | 1 week template 5–10 days fabrication | Stone templater visits with cabinetry installed. Returns 5–10 days later with fabricated benchtops. Benchtop cannot be templated before cabinetry is fully in place. |
13. Plumbing and electrical fitoff | 1–2 weeks | Taps, toilet, shower fittings, sinks connected after benchtops are in. Downlights, exhaust fans, pendants, and switch gear installed and tested. Compliance certificates issued by each licensed trade. |
14. Shower screens, doors, and glass | 3–5 days | Frameless shower screens templated to actual finished dimensions. Glass pool fencing if in scope. Sliding or bifold door installation. |
15. Exterior works | 2–4 weeks | Render, paint, new windows or doors, garage, driveway, landscaping — typically run concurrently with interior fitoff stages. Exterior trades do not conflict with interior fitoff trades. |
16. Painting and finishing | 1–2 weeks | Final trade in every room. Painted after cabinetry, benchtops, screens, and fittings are all in place. Only one paint visit — not multiple returns. |
17. Sealant, cleaning, and final inspection | 2–3 days | Fresh silicon in all wet areas. Deep clean throughout. House & Co walkthrough with client. Defects list raised and completed before handover. |
Home Age | Contingency Recommended | Contingency Recommended |
Contingency Recommended | 8–10% | Clean property — low risk. Standard materials throughout. |
1985–2000 | 10–12% | Some galvanised plumbing possible. Older electrical may need upgrading. |
Pre-1985 | 15–18% | Asbestos likely in wall linings. Galvanised plumbing probable. Electrical non-compliance likely in places. |
Pre-1960 character | 18–22% | Asbestos almost certain. Original plumbing and electrical throughout. Possible termite damage. Budget generously |
In Perth’s 2026 property market — where the median house value has crossed $1,000,000 for the first time and annual growth is running at 18.4% (CoreLogic, January 2026) — a full home renovation can add extraordinary value when the project is executed correctly.
The $500,000 uplift across three different projects in three different suburbs is a consistent outcome when a full renovation is properly scoped and executed. The renovation itself — roughly $150,000–$300,000 depending on scope — generates a return that significantly exceeds its cost in Perth’s current market
This is not guaranteed. Return depends on the suburb’s price ceiling, the condition of comparable properties in the street, and the quality of the renovation. Properties that are overimproved for their suburb will not return the full renovation cost at sale.
How much does a full home renovation cost in Perth in 2026?A full home renovation in Perth costs between $100,000 and $500,000+ in 2026, depending on the size of the property, the rooms included, and the specification. A focused renovation covering 2–3 key rooms and the exterior costs $100,000–$180,000. A mid-size full home transformation costs $180,000–$300,000. A complete inside-and-outside renovation of a large Perth home costs $300,000–$500,000+. These are guide prices — a fixed-scope quote after an in-home consultation is the only accurate figure.
How long does a full home renovation take in Perth?A full home renovation in Perth takes 5–12 months from first consultation to completion. On-site construction takes 8–24 weeks depending on the scope. Design and trade booking add 4–8 weeks. Permits add 4–10 weeks where required. The critical path items are: cabinetry manufacture (4–6 weeks), licensed trade booking windows (10–16 weeks in Perth’s 2026 market), and permit approval where structural changes are involved. Start the consultation process at least 4–6 months before your target completion date.
What does a full home renovation in Perth include?A House & Co full home renovation typically includes: kitchen (full strip-out and replacement), bathroom and ensuite renovation, laundry, new flooring throughout, painting, updated lighting, structural changes as required (wall removal, new openings), exterior repaint or re-render, alfresco upgrade, and electrical and plumbing assessed and upgraded throughout. All licensed trades are coordinated under one fixed-scope agreement with one project manager.
Do I need to move out during a full home renovation?In most cases, yes — a full home renovation involves simultaneous construction across all rooms, including wet areas, kitchen, and living spaces. Living in the property during a full renovation is extremely difficult and typically slows the renovation down by reducing the hours trades can access the site. Budget for alternative accommodation during the on-site construction period — for most Perth full renovations, this is 3–6 months.
What is the biggest risk in a full home renovation?The three biggest risks are: hidden works in older properties (asbestos, galvanised plumbing, non-compliant electrical — addressed through pre-quote property assessment and appropriate contingency), client decision delays (every delayed decision delays a subsequent trade — the timeline is only as fast as the decision-making), and underbudgeting (using national averages rather than Perth-specific pricing, or not including an adequate contingency for the property’s age).
How much uplift does a full home renovation add in Perth?House & Co’s full home renovations in Morley, Inglewood, and Dianella each achieved approximately $500,000 in property value uplift. Perth’s median house value crossed $1,000,000 in early 2026 with 18.4% annual growth (CoreLogic). In this market, a well-executed full home renovation can add value significantly in excess of its cost — particularly in inner Perth and gentrifying suburbs where the gap between unrenovated and renovated properties is widest.
What is included in a House & Co full home renovation quote?House & Co provides fixed-scope quotes covering: 3D design of every room before any trade is booked; all licensed trades (plumber, tiler, electrician, cabinet maker, painter, renderer, landscaper as required) coordinated under one agreement; all materials in the specification; project management from first consultation to handover; and compliance certificates from every licensed trade on completion. The price you sign is the price you pay — variations are only raised for client-initiated scope changes.
