Value and review

The sales data is from around 2009 and the dollar figure is in 2009 dollars — treat it as a proportion, not a number you can bank in 2026. The UWA repository page carries the abstract, findings and the accepted author manuscript for free; the publisher's version behind the DOI is paywalled.

This measures what Perth buyers paid in 2009, not what makes a good garden. Hedonic models cannot see design quality, and a negative price signal on private canopy is not an argument for cutting your trees down — shade, cooling and amenity are real returns that never appear in a sale price.

Sales data is annual to the latest completed month, so it lags a fast-moving market. Your suburb median matters far more than the metro median for a decision about garden spend.

GRV is a rating valuation, not a market valuation, and it is not evidence of what a buyer will pay. Read it as the ongoing cost side of the ledger, not the return side.

Fees and forms are state-level; the assessment is done by your local government, and it will want a certificate of design compliance from a registered building surveying practitioner before it issues anything. Confirm current fees with your council.

Every Perth local government runs its own street tree and verge treatment policy, with different species lists, planting windows and rules about what else you may put on the verge. Use this as the shape of the process, then find the equivalent page for your own council.

This is market commentary, not landscaping research — checked on 2 August 2026 the current issues covered national residential, office and agribusiness overviews with no landscaping-specific content. Read it for how valuers reason about improvements and comparable sales, not for a number about gardens.

British public-sector appraisal guidance, prepared from Mott MacDonald's 2002 review of large public procurement in the UK and aimed at hospitals and railways, and the percentages are calibrated to that world — do not treat 51 per cent as your garden's number. What transfers exactly is the method: start at the upper bound, reduce it only where you can point at something you actually did to manage the cause, and code every overrun to one contributory factor. The contributory factor list in Tables 2 to 4 is the best variance taxonomy available free.

The four-month window is a written-notice window. A verbal complaint on site does not start it, and neither does a text message you cannot later produce. Send an email or a letter with photographs and dates, and keep the sent copy.

Checked on 2 August 2026, the site carries a standing notice that Climate Data Online daily rainfall and temperature data tables have not been updating since 20 May 2025, and directs users to the 'Daily — Weather & climate' data type on the same page for daily data instead. The notice names only the daily rainfall and temperature tables. The site also blocks some automated tools — open it in a normal browser.

North American, and mostly public parks, campuses and streetscapes rather than domestic gardens, so the projects are not comparable to yours in scale or budget. Take the method — pick a small number of measurable claims, state the baseline, measure after — and ignore the benefit calculators, which are built around US stormwater and carbon accounting rather than Perth sand and a two-day sprinkler roster.

Written for software teams running sprints, and sized for four to eight people. On your own project you are both the facilitator and the entire team, so run it with the person who used the garden with you — the partner, the flatmate, whoever was told the pergola would be finished by Christmas. Their version of the timeline is data you do not have.

The guide itself is free to download. Actually entering costs $350 plus GST per entry and entries are restricted to AILA Registered Landscape Architects, so treat this as a template for structure, not something you can submit a home renovation to. The WA Chapter runs its own program under the same national rules.

This is a member awards document, and the residential categories are open to LIAWA member businesses, not to homeowners. Use it as a scoring sheet, not as an entry form.

Issued for Australian Government agencies and their statutory obligations, not for households, and it applies to files created digitally rather than scanned. The format list is what you want; ignore the compliance framing around it.

General guidance, not advice on your circumstances. If part of your block has ever produced income, or the property was inherited or transferred after a relationship breakdown, the record set you need is larger — talk to a registered tax agent.

Fees, date ranges and turnaround are specific to the City of Vincent and change each financial year. Every Perth local government runs its own archive search with its own fee — find the equivalent page for your council, and note that a search only ever returns approved records, not planning refusals or cancelled permits.

Fremantle, on a subdivided lot, and built as a demonstration project with a budget and a research program behind it. Read it for the documentation format and the reasoning, not as a benchmark for what a suburban renovation should cost.
