Office figures: Prague Research Forum (CBRE, Colliers, Cushman & Wakefield, iO Partners, Knight Frank, Savills), Q2 2026 — 229,100 m² vacant, 5.8% of 3.95 million m² of modern offices; highest in Prague 10 (11.4%) and Prague 3 (11.2%). Map built 2026-10-10.
A tour in 3D
A building checked against today's sources and found empty — a site that could be well suited to the EHC model. A short film: how it could come back to life, with what our conversion check and economic model say it could hold. A potential we spotted, not a plan.
Together, room for ≈ 17 homes for ≈ 39 people — a potential, not a plan.
Every building a record says stands empty, one point per building: filter by type, size and how sure the evidence is, and open one to see who says so. “Opportunities” switches to the co-op lens: public land, conversion potential and projects already under way, every source as its own layer.
0 empty buildings · colour = type, dark ring = confirmed
Check any building in Prague: could it become homes, and could the EHC model work there?
Buildings with evidence that they stand empty — a second source agrees, a public record names them, or we have checked them — ranked by a score you can read: co-op scale, daylight depth, a station nearby, a zone that allows homes, affordable land and an open route in. Checked buildings carry their result; nobody has visited them on site yet. Leerstandsmelder reports join the list when they sit in a large non-residential building and a second source agrees.

Where empty offices, the right zoning and a working neighbourhood come together — and what could go wrong.
The most mapped unused buildings of any district, the City's largely empty Karlín barracks, and many administrative buildings by the river.
Risk: Karlín is one of Prague's priciest office and housing districts; the barracks programme leans to culture and student rooms.
The City owns more buildings here than anywhere else, and several stand unused — including burgher houses by the Old Town Hall.
Risk: Listed buildings in the heritage reserve: costly repairs and strong pressure for hotels and short-term letting; office vacancy only 3.7%.
The highest office vacancy in Prague and large transformation land around the Žižkov freight station and the Orionka factory site.
Risk: Transformation land is largely in railway and developer hands; homes come only with new structures.
The largest number of buildable transformation areas in the new plan, and the City's Skloněná hostel waiting to become 152 rented homes.
Risk: Former industrial land with contamination and long planning; the hostel conversion has already been re-tendered once.
Who controls the space, and what a housing cooperative can actually do with them.
The City publishes its building register and is converting unused buildings (Skloněná, Kasárna Karlín) itself; ask for the City buildings IPR maps as unused that have no programme yet, and propose the building's co-op as tenant or long-lease partner.
The State's property office lists surplus property on nabidkamajetku.gov.cz in separate offers to state bodies, to municipalities and regions, and to the public (electronic auctions, sales, leases); a co-op can bid in public offers or partner with the City or a district on offers made to them.
Transformation areas need structure and public-amenity rules met before building; early talks with landowners and the city district can secure a share of homes for a co-op in a new quarter.
Districts manage much of the municipal stock and keep their own lists of endangered buildings; they can lease or sell buildings they look after.
Decisions, auctions and closures that change what becomes available, and when.
The district's property portal counts 1,432 shops, offices and other non-residential units it owns: 1,107 let, 126 free and 199 in the letting process; only 16 are on offer this month.
Prague's new zoning plan concentrates building on brownfields near rail and allows new quarters for up to 350,000 homes.
The City will spend about CZK 1.9bn; works to finish in 2032.
229,100 m² of modern offices empty; Praha 10 and Praha 3 above 11%.
IPR's survey of current land use, which marks buildings without use (code XO), was last updated in May 2026: 653 such areas across the city.
The City cancelled and re-issued the design tender for 152 rental flats in its unused hostel.
A new 70 m² flat costs 15 average gross annual salaries, 1.7 more than a year earlier (Deloitte Property Index).
Answering a councillor, Prague 5 named 52 empty units it owned on 31 Dec 2023 — 5,670 m², about CZK 1.17 million a month in unlet rent — including four floors of Radlická 3 and a unit to be converted to flats at Vrchlického 41A.
