Precincts and character around Blaxland
Where three roads met
Council history says Blaxland grew at the meeting point of the three earliest roads that crossed the eastern escarpment. The station opened in 1867 as Wascoe's and was renamed in 1879. Census 2021 figures show 7,434 residents across 2,887 private dwellings. Of the homes occupied, 91.9% were detached houses, 7.7% attached and just 0.5% flats.
Three residential precincts
Blue Mountains Local Environmental Plan 2015 (the LEP) sets out different aims for neighbouring areas. R3-BX02 looks for integrated redevelopment with active frontages. R3-BX03 wants a bushland feel and no driveways opening directly onto the Great Western Highway, plus visual and acoustic privacy between homes. R3-BX04 expects street-facing work to suit single-storey weatherboard cottages, keep the eucalypt pattern and blend parking into gardens. Two lots only a street apart may meet very different tests.
Centre plans and slopes
Council's masterplan for the town centre is a guide to the future, not an approval for your lot. The current LEP and Development Control Plan (DCP) still apply. Town-centre aims about hillside form and National Park views are design goals; they do not find a hazard on nearby homes.
Typical work
Common projects and how they get approved
What owners build here
Popular Class 1 and 10 projects in Blaxland:
- Dual occupancies. Lawful vehicle access must be solved before the floor plans, especially in R3-BX03.
- Cottage additions. In R3-BX04, the street elevation needs as much care as the new rooms.
- Garages and carports. A large garage can change the intended garden frontage.
- Decks and outdoor roofs. Where the lot slopes, show posts, footings and drainage on the survey.
- Granny flats. Check access, parking and the precinct's landscape aims before siting one.
How approval usually works
Small jobs are sometimes exempt, provided they comply with the state standards. A CDC, a quick approval a certifier issues when a design meets set codes, may suit additions and some new homes. Other projects need Blue Mountains City Council to approve a development application (DA), and a construction certificate (CC) comes next. Highway access, heritage listings and higher bushfire ratings are common reasons a CDC will not work. A sloping lot may also need retaining and drainage details at the start. Where a precinct limits access or protects the garden frontage, a new garage, carport or driveway can turn into the trickiest piece of the design. Once approved, the same levels and access must flow through to the construction drawings and every inspection. Bring a survey, street photos and any old approvals to the first meeting. CertifiBuild is ready to sort the pathway early so your drawings only need doing once.

Local questions
Questions we hear about this suburb.
No two lots in Blaxland are the same. Give us your address and we will check every map that affects it.
See the council pageCan my Blaxland driveway open straight onto the Great Western Highway?
Do not assume it can. In precinct R3-BX03, Blue Mountains council’s local plan specifically aims for development with no driveways opening straight onto the Great Western Highway, along with a bushland feel and privacy between homes. An existing frontage or a neighbour’s crossing proves nothing. Check your lot’s precinct mapping first, then find out what the road authority requires. Solve lawful car access before a garage or car space goes on the plans, especially for a dual occupancy, since access can reshape the whole layout.
Will the Blaxland town-centre masterplan affect my building options?
Not by itself. Council’s masterplan for the Blaxland town centre sketches a preferred future, but it is a guide, not an approval for any lot. Your project is still assessed under today’s local environmental plan (LEP) and development control plan (DCP), plus any adopted change that genuinely covers your lot. Goals in the centre plan about hillside form and National Park views guide design only. They say nothing about hazards on nearby homes. So start from your own survey, zoning and precinct, and treat concept drawings as background only.
How should a Blaxland weatherboard cottage be extended?
If your lot is in precinct R3-BX04, keep the single-storey cottage look from the street and protect the established eucalypt pattern. Put most of the new space behind the original house, where it is less visible, and blend any parking into the garden rather than letting a big garage take over the front. Give the drawing of the street front, and the gardens you are keeping, just as much care as the extra rooms. On a sloping lot, add levels, footings and drainage to the survey early. Outside that precinct, other aims may apply, so confirm the mapping first.
