Detailed design and documentation

UK site. The geometry is climate-independent and identical in Perth, but the surrounding pages assume UK materials, frost and clay subgrades. Ignore the base build-up advice there and use the Perth crushed limestone build-up from Phase 8 instead.

These are design and concept sheets from a demonstration project, not a construction setting-out plan, so do not expect a complete dimension set on them. Use them as a model for sheet structure, title blocks and notes — not as a source of dimensions for your own block.

Nothing Perth-specific — CAD geometry is the same everywhere. Set your drawing units to millimetres before you draw anything, because every dimension in this course is in millimetres.

Web-based, so it needs a connection. Model in millimetres, and treat anything you trace over an aerial image as indicative shape only — never as a set-out dimension.

BYDA returns the asset owners' plans, not a marked-up site. The same page tells you to use skilled locators and to hand-dig to expose assets, which is the tell that the plans are indicative positions only. In Perth the responses come back separately from Water Corporation, Western Power, ATCO and the telecommunications carriers, and they arrive at different speeds.

The R-Codes are state policy applied through your local planning scheme, and councils commonly adopt local planning policies that vary them. Read your own council's version alongside the state document before you fix a boundary dimension.

Fees change. This page was last updated 23 July 2026 — confirm the current figure on the form before you pay. Building and Energy also directs you to your local government for local requirements, so ask your council whether the work needs a permit at all before you assume it does or does not.

North American document. Ignore the freeze-thaw and frost material entirely, and substitute compacted crushed limestone for the crushed aggregate base it specifies, because that is the Perth standard. Its herringbone recommendation is aimed at trafficked streets; a pedestrian courtyard here has more freedom in pattern.

Western Australia adopted NCC 2025 on 1 May 2026 with a 12-month transition, so work permitted during the transition may be assessed against either NCC 2022 or NCC 2025. The 3.3.3 figures quoted here are identical in both editions, so the numbers do not change; the clause numbering does not either.

The 1:2 sand figure is the batter you can hold without a wall, which on a Perth block means a 600 mm level change eats 1.2 m of horizontal space. On a typical 400 to 500 square metre lot that is usually the moment terracing with a wall becomes cheaper than battering. Your council may also require a building permit or engineering for the wall itself — see the approvals phase.

These provisions bind stairways that form part of a building. A freestanding garden step in the middle of a lawn is not automatically caught, but the dimensions are the safe-movement benchmark a court, an insurer and a building surveyor will all reach for. Design to them anyway. Where your steps are part of the path to the dwelling entrance, they are caught.

Joondalup's own sheet, last updated July 2016, and the containment rule is common across Perth councils rather than unique to Joondalup. The design storm, the soakwell sizing chart and the setbacks vary between local governments — confirm the current figures with yours before you size anything.

Written for catchment and subdivision scale, not for one garden, and chapters 3 and 4 have been superseded by other planning documents. Take the principles and the device design from Chapter 9 and ignore the planning-process material.

It is called up by the NCC for new dwellings. On a renovation to an existing house it is not being enforced against your garden, but it is the only free, national, dimensioned reference for step-free access and it costs nothing to design to.

City of Stirling only. Every Perth local government has its own crossover specification, setbacks and subsidy — read your own council's before you set a driveway level.

Written for a crossover in the road reserve, so the loading is heavier than a courtyard and the widths, wing dimensions and 2% verge gradient are Wanneroo's own. Your council's crossover specification will differ in detail. Use it as a materials and workmanship benchmark for your own paving, not as an approval document.

North American. Ignore everything about freeze-thaw. Substitute compacted crushed limestone for the crushed aggregate base — that is the Perth material. Its geotextile trigger is saturated, clay or silty subgrade, which describes very little of the Swan Coastal Plain, so on clean sand most Perth builds omit it; keep it where you are working over clay, over old fill, or over a soakwell surround.

Imperial units with metric conversions. The proprietary plastic and aluminium restraints it describes are less common in Perth than a poured concrete haunch or a course of bedded bricks, but the sizing logic transfers directly.

National, so it does not name Perth's wind region or bushfire requirements. If your block is in a designated bushfire prone area, decking material and sub-floor enclosure are additionally constrained by AS 3959 and you must resolve that before you finalise the detail.

This is a paving retailer's own document and it exists to sell blocks, so treat product-specific claims as advertising. It is South Australian, and unreinforced height limits are product-specific — the maximum heights in its diagrams are not a substitute for your council's threshold or an engineer's design. In WA, check the permit trigger first: most Perth councils bite at 0.5 m.

Stirling's document, last updated December 2021, and thresholds vary between Perth councils. The City of Joondalup, for example, publishes a similar 0.5 m trigger but adds conditions about work for the protection of adjoining land. Confirm the current figure with your own council before you commit a wall height to the drawing.

The NCC is national but adopted state by state. Western Australia adopted NCC 2025 on 1 May 2026 with a 12-month transition, so a job documented earlier may still be assessed against NCC 2022 — the damp-proof course clearances are materially the same in both.

Written for workplaces under the WHS Act. A homeowner digging their own footings is not the regulator's target, but the physics is identical and sand collapses without warning. If your detail requires a trench approaching 1.5 m — a deep wall footing or a drainage run — redesign it or engage a contractor with shoring.

Expensive for one garden, and it excludes Class H1, H2, E and P sites — reactive and problem soils — which is not usually a constraint on Perth sand but matters on the clay pockets in the eastern suburbs and the hills. If you are not buying it, the City of Wanneroo crossover sheet and the CMHA tech notes above give you most of the same numbers for free.

This is an engineer's document, not a builder's manual — it will not tell you how to lay a block. Do not buy it to build a wall. Buy nothing, and instead pay a structural engineer for a certified design on any wall over your council's threshold, over about 1 m, or carrying a surcharge such as a driveway, a pool or a neighbour's fill.

This is City of Stirling's rule. Do not apply the 0.015 m factor in another local government area without checking — Claremont and East Fremantle use 0.0125 m, and other councils publish tables rather than formulas.

Town of East Fremantle publishes a near-identical sheet with the same 0.0125 m factor and the same setback rule, so this wording is common across several western suburbs councils, but it is still not universal.

Western Australia adopted NCC 2025 on 1 May 2026 with a 12 month transition, so NCC 2022 may still be the applicable edition for a permit lodged before 1 May 2027. Check which edition your permit authority is assessing against before you quote a clause number.

Free alternative: ABCB Housing Provisions Part 3.3, listed above, covers everything a single suburban block needs and costs nothing. State Library of WA and TAFE libraries also provide member access to Australian Standards — ask before you spend $318.

A 200 page engineering document written for consultants and councils. Skip to section 3.2 (page 81). The costs quoted in it are from 2000 to 2007 and are useless today.

It is a map viewer, not a report — enter your address and read the depth-to-watertable layer. It gives estimated and maximum levels, not a certified figure; if the number is marginal, a geotechnical report is the next step.

It returns network owners' plans only. It does not show private property-side services — the old power run to a shed, unmarked poly, or the previous owner's abandoned soakwell. Cross-reference with your own site survey and pothole by hand near anything marked.

This is a transitional code, originally approved under the Occupational Safety and Health Act 1984 and continued in effect under the Work Health and Safety Act 2020. A replacement Code of practice: Excavation work has been through public consultation, so check the WorkSafe publications page for a newer version before relying on clause numbers.

This is a Perth soakwell retailer's own site and the calculator exists to sell you polypropylene soakwells, geotextile and pipe. Use it to check a number you have already worked out by hand against your council's published rule — never as the source of the rule. Prices shown are the retailer's.

Checked on 2 August 2026, the Water Corporation waterwise homepage was carrying the live banner that the Switch-off is currently in effect. Confirm the areas covered with the postcode checker rather than assuming your suburb is in or out.

Apply on the day of installation. Applying late still works but the clock runs from the installation date, not the application date, so you lose the days you waited.

The 10 mm per watering day target is a Perth default for sandy soil on a two-day roster, not a plant water requirement. Hydrozoning is exactly the process of departing from it deliberately, and Phase 8 revisits the number with catch-cup data from your own block.

Endorsement means the business has been trained in the program's best-practice guidelines and appointed to deliver it, not that it is the cheapest or the most independent — a design shop sells product. The directory also lists Victorian members, so filter by state.

BYDA only shows registered network assets. It will not show the previous owner's unmarked poly, the abandoned power run to the shed, or the soakwell nobody recorded — which on a renovation is most of what you will hit.

It does not filter by mature height or by aspect, so it narrows your list but does not size or place anything. It also treats 'readily available' loosely — availability of a species is not availability of that species in a 45 litre bag in the month you want it. Confirm the size with a grower.

It is a water utility's list, so it is biased toward protecting sewer and water mains. Moderate and high root ratings are a warning about pipes, not a horticultural verdict — a moderate-rated tree can be entirely correct in the middle of a lawn away from services.

These are revegetation species chosen for local provenance, not ornamental performance. Many are tubestock-only and will not be available at 200 mm or in bags. Treat the output as a shortlist to test against your hydrozones, not a planting plan.

This is the 2025 edition and a 2026 catalogue has since been published, so confirm current prices with the nursery before you total anything. Trillion Trees (formerly Men of the Trees) is at Hazelmere and grows tubestock only — it will not solve your advanced tree lines. Retail sales are Thursdays and Fridays, 9am to 2pm.

Trade and wholesale only. The site says 'sign in for pricing' — you cannot see a dollar figure without an approved credit account, and homeowners will not get one. Use it to check what exists and in what sizes, then get the price through a landscaper, a garden centre that will order in, or a retail equivalent.

Membership is a trade association, not an accreditation of plant health or quality. Being listed here does not mean a nursery is NIASA accredited or dieback-free; ask that question separately.

Written from a Victorian practice, so the example species and the seasonal timing are wrong for Perth. The drafting method transfers unchanged; the plants do not.

National research, not WA-specific. It says nothing about which species suit Perth sand; it is about whether the tree you are handed is a well-grown specimen for its container size.

Overkill for a suburban garden of shrubs and tubestock. If you are buying one or two advanced trees, read the free Western Sydney University material listed above and inspect the root ball yourself instead. Buy the standard only if a supplier is disputing a rejection.

Checked on 2 August 2026: the first round opened 28 July 2025, the funding counter showed roughly 90% allocated by June 2026, and the page flagged a second round as coming. The scheme is capped at around 10,000 claims a year across four years and allocations run out, so confirm the round is open before you rely on the $150.

A new-build on a small Fremantle lot, so the scale and the soil are specific to that site and the plans are free to use and share with attribution. Read it for structure and palette logic, not to copy species onto a different soil type.

A long consolidated instrument written for lawyers. Use your browser's find function for 'electrical work means' rather than reading it front to back, and check the compilation banner at the top — the version read for this lesson carried amendments up to SL 2023/30.

It is a JavaScript search application, so the results do not render in a plain-text browser and there is no shareable link to an individual licence. Search by the licence number printed on the quote.

A US lighting retailer's learning centre, so treat the product links as advertising. Beam geometry is physics and transfers unchanged, but bear in mind Perth's pale limestone, liquid limestone and rendered walls bounce far more light than the dark brick and timber in their photos — start a step lower in output than they suggest.

US retailer content aimed at large American front yards. The techniques are universal; the scale is not. On a Perth block, one or two feature effects is the whole budget, and anything aimed up must be shielded and kept off the boundary.

An astrotourism body, not a regulator, and the guidance is principles rather than numbers — there are no Kelvin limits or lux figures on the page. Its concern is the night sky over regional WA; on a suburban block the same rules mostly protect your neighbour's bedroom window.

A young scheme with a limited product list, weighted toward street and commercial lighting rather than 12 V garden fittings, so expect gaps. The detailed criteria live in a downloadable PDF rather than on the page itself.

A manufacturer's catalogue selling a proprietary connector system, so you are locked to their plugs and to whatever the controller is rated for. Price and compare against cut-and-join cable systems from a Perth electrical wholesaler before ordering a large garden.

The $50,000 Class 10a change took effect on 1 July 2026 and covers patios, pergolas, carports, sheds and similar non-habitable structures. It does not remove the need for a building permit, and it does not apply to Class 1 work.

This is one local government's page and the statutory timeframes come from the Building Act 2011, so they apply across WA. Fees, required drawings and local policies differ by council — get those from your own local government.

The page does not publish processing times or fees, so treat the lead time as unknown and apply as soon as your layout plan is fixed. Confirm the current fee schedule with Water Corporation before you cost it.

This is a commercial arboriculture consultancy's summary, not the standard itself, and it is written partly to sell arborist services. The summary of the changes is accurate; buy or borrow AS 4970-2025 before you rely on specific numbers, and note the standard is national, not WA-specific.
