Office figures: Monitor Staat van de Haagse Economie 2024 (Cushman & Wakefield, spaces of 500 m² and more): vacancy 4.5% of the stock; office floor area 3.61 million m² in BAG (2024); vacant area = stock × rate (an estimate). Knight Frank (April 2026) puts the Binckhorst at 17%, the core districts below 5%. Map built 2026-10-09.
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 ≈ 28 homes — 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 The Hague: 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.

Of 1 Leerstandsmelder reports on the map, 1 sit in a building we can identify — 1 of them homes. These are whole buildings of flats that people report empty, ranked by a reactivation score: co-op scale, whether the whole building is empty, how recent the report is, location and land. A building of flats needs no change of use. Reports are public and not checked by us — each card links to its entry on Leerstandsmelder.

Where empty offices, the right zoning and a working neighbourhood come together — and what could go wrong.
The office district with the highest vacancy in the region, in transformation, with the empty State office on the Regulusweg.
Risk: Large plots are in developers' hands and planned for new build; the Regulusweg office is earmarked for civil servants from 2028.
Public and institutional owners hold long-empty buildings in the old centre.
Risk: Monument rules and split entrances make upper floors hard to use; the police building sits next to a secure yard.
Long-empty former telephone exchange and the stalled De Zaen block.
Risk: Private owners; De Zaen is under enforcement after its permit was revoked.
Former telephone exchange and a sold State office near the Beatrixkwartier.
Risk: Both now belong to private developers with their own plans.
The Azivo building, a city symbol of long vacancy since 2011.
Risk: The owner now holds a permit to demolish and build 68 homes.
Who controls the space, and what a housing cooperative can actually do with them.
Under the Nota Vastgoed 2025, city buildings empty for more than five years without a plan are reviewed for sale or temporary social use, and the city's vacancy managers must place social initiatives. Ask for long-empty city buildings to be offered to a co-operative before a sale.
The city aims for 100 homes in innovative forms of living, has inventoried locations suitable for housing co-operatives and is drawing up tender conditions with Centrum Groepswonen. Register interest and ask for existing buildings to be included.
A draft ordinance that lets the city require use of long-empty homes is ready; it waits for the national regulation (ambition: second quarter of 2026). Once in force, offer the co-operative as user for blocks the city flags.
The State is The Hague's largest office owner. Its disposals go out through Biedboek (Neuhuyskade 32 sold in December 2025); watch Biedboek and ask the city to press for empty State buildings, such as the Regulusweg, to be used meanwhile.
If the police drop the planned extension, they will explore selling (parts of) the building with its current zoning, which allows homes. Ask to be told before it goes to market.
Decisions, auctions and closures that change what becomes available, and when.
Koningin Sophiestraat 27-29, empty since 2024, is to be replaced by homes for starters and older people.
HMC lets part of it under vacancy management meanwhile; the chapel may become a municipal monument.
Empty under vacancy management since September 2025; the State will convert it into a swing office by the end of 2028.
A 1927 office of 2,253 m² sold through Biedboek for €3.28 million.
City buildings empty for more than five years without a plan are to be reviewed for sale or other use (Nota Vastgoed 2025).
5.4% of homes on 1 January 2024; 6,122 empty for more than two years; vacancy ordinance delayed by national rules; De Zaen's permit revoked.
