Building by mesh block — the homes on each block within 1 km (by gnaf_id)
/v1/properties/{gnaf_id}/mesh-blocks/building20¢ per callWhat are the homes like? For every mesh block around the property: how many properties, the share of houses and strata, median bedrooms, bathrooms and building size, building height, and recent construction.
One entry per mesh block within 1,000 m of the property under mesh_blocks, nearest first, each with its mb_code, distance_m, population and dwellings. Blocks across suburb lines are included. Values only — the polygons come from /properties/{gnaf_id}/context/mesh-blocks.
Every field carries provenance — measured (at this block), measured_wider_area (measured for the SA1 or postcode and repeated on every block in it), estimate (our model) or not_recorded (not labelled yet) — plus how, one sentence on how the number was arrived at (empty when not_recorded).

topicstringalways returnedWhich topic this answers.
questionstringalways returnedThe question this topic answers.
betabooleanalways returned`true` when the figures behind this topic have not been validated against an independent source yet.
beta_noticestringmay be nullWhat is unvalidated, on beta topics only.
block_countintegeralways returnedHow many mesh blocks are in `mesh_blocks`.

About this data
What this is
The homes around one address, block by block: for each mesh block within 1 km, how many properties it holds, the share of houses and strata, median bedrooms, bathrooms and building size, building height, and recent construction.
What people use it for
- Buyers: see whether a street is mostly family houses, units or a mix.
- Developers: read the existing built form and height around a site.
- Valuers and analysts: check that comparable homes really are comparable in size and type.
Coverage
Mesh blocks nationwide (about 368,000). The 1 km radius crosses suburb lines. A field is null where we hold nothing for that block.
Tips
For the planning rules that apply to the site itself use /v1/properties/{gnaf_id}/development/zoning-code. Check provenance before quoting a field. Whole suburb: /v1/suburbs/{suburb_name}/mesh-blocks/building. Polygons: /v1/properties/{gnaf_id}/context/mesh-blocks, joined on mb_code.
