Bratislava

Bratislava's brownfield study lists 113 surveyed sites, 50 of them with buildings and no use — 17 owned by the City or the State — and the City's 2026 survey of its rented non-residential premises marks 14 units as vacant or unusable, among them the empty 1,130 m² administrative building at Štetinova 2 and a 600 m² building in emergency condition on Ventúrska. Modern offices stand 13.4% empty (235,500 m²) while a flat costs 12.3 average annual salaries.

Office figures: Bratislava Research Forum (CBRE, Colliers International, Cushman & Wakefield, iO Partners), Q2 2026 — 235,500 m² vacant, 13.42% of 1.75 million m² of modern offices (A+ 8.86%, A 16.72%, B 12.79%); no new office completed in the quarter. Map built 2026-10-09.

Empty buildings in Bratislava

One point per building, from public records, open data and cited reports. Filter by type, size and how sure the evidence is; open one to see who says so and whether it could become homes.

Slovakia has no open building register with use or storeys: the national INSPIRE buildings WFS answered "disabled" on 8 October 2026 and with a bot-management page on 9 October (not worked around), and the City's 3D heights cover residential buildings only — so floor areas come from the Global Building Atlas.

  • bývalé letisko Vajnory — reported conversion planned · owner: JTREThe unused former airport, empty since 2007, is envisioned as a new urban district Trend (2025-05-21)

Where conversion makes sense, and who to talk to

The districts where empty space, the right zoning and a working neighbourhood come together, and the owners and programmes that open a door. 235,500 m² of offices stand empty (13.42% of the stock).

Nové Mesto and Staré Mesto

The district with most empty brownfield buildings (15 of the 50), the State-owned 22-storey Kukurica tower, and a row of vacant City premises in the old town (Štetinova 2, Panská 4, Ventúrska 4, Kozia 9, Mýtna 31).

  • 15 brownfield sites with buildings and no use in Nové Mesto, 2 in Staré Mesto (study, update 2022)
  • Štetinova 2: 1,130 m² administrative building recorded empty (City survey 2026)
  • Kukurica, Kukučínova 38: 22 storeys, State-owned, no use

Risk: The old-town premises are mostly small units in occupied buildings, and the State controls the largest tower; heritage rules cover the centre.

Petržalka and the south

The City's largest vacant premises outside the centre — Beňadická 21 (1,948 m²) — and a City-owned former nursery on Znievska, in the district with the most City-owned built plots.

  • 6 brownfield sites with buildings and no use in Petržalka
  • Beňadická 21: 1,948 m² vacant, poor technical condition (City survey)
  • Znievska 26: City-owned former nursery on 0.8 ha, no use (surveyed 2016)

Risk: Large panel estates with few empty buildings; the study surveyed the south in 2016 and 2022.

2 sources

Ružinov and Trnávka

The City-owned Bazová yard marked "locality for rental housing", the unused 2,610 m² administrative building beside it, and the abandoned City complex on Vietnamská in Trnávka.

  • Bazová 8: unused administrative building of 2,610 m² (City survey, May 2025)
  • Technical services (OLO), Bazová: 1.5 ha, owner's intent "locality for rental housing" (study)
  • Vietnamská 15–21: three buildings on 1.1 ha, City-owned, no use (surveyed 2022)

Risk: The yard still houses the City's technical services; both sites wait for the services to move.

Read from the EEA's open ArcGIS services, the same way in every radar city. The 2021 edition (Copernicus Data Space) drops plots built on since 2018 where scripts/reuse/import-urban-atlas-2021.ts has been run. Points are context, never evidence of vacancy.

Where no register dates a building: its era read from a Panoramax or Mapillary photo looking at it — Google Street View only where no open photo answers (scripts/reuse/estimate-photo-eras.ts), only when the building is clearly visible and the model is confident, and only as “before 1945” or “1945 or later” — the split it got right for 89% of buildings with a register year in Amsterdam and Paris, and 89% from Street View pictures alone (photo-eras/calibration.json).

What this radar cannot see yet

  • Slovakia has no open building register with use or storeys: the national INSPIRE buildings WFS answered "disabled" on 8 October 2026 and with a bot-management page on 9 October (not worked around), and the City's 3D heights cover residential buildings only — so floor areas come from the Global Building Atlas.
  • The City's three key layers (brownfield study, property register, rented-premises survey) state no licence; the City could add one (CC BY 4.0, as on its 2025 property table).
  • The brownfield study dates from 2016–2022; the 2026 update survey is not yet published. Records are sites, not buildings.
  • No vacancy register, empty-homes tax or council list of empty buildings exists; only what the City reports about its own premises is visible.
  • The ministry's national brownfield mapping project (Košice, Prešov and five other regions, not Bratislava) will give a national database later; the cadastre's building-type code list (DRS) was not verified.

Know an empty building we have missed?

Open data cannot see everything. Tell us about a building in Bratislava that stands empty or barely used; once we have checked it, it joins the map under “Reported by visitors (checked)”.
