Hévíz Lake Bath redevelopment: iconic bathhouse faces demolition plans

Hungary has launched a major design competition that could reshape the future of Hévíz Lake Bath redevelopment, one of the country’s best-known health tourism destinations. The plans cover not only the lakeside bath complex built over Europe’s largest biologically active natural thermal lake, but also the adjoining Szent András Rheumatology Hospital in Hévíz, western Hungary.

What is happening now?

According to Hungarian construction and tourism industry reporting, the Ministry of Construction and Transport has opened a design competition for the комплекс (spa + hospital) with a submission deadline at the end of July. A professional jury is expected to decide by late September, after which the state plans to select a team to produce the permitting and detailed construction designs.

The project has been presented as strategically important for the long-term operation of one of Hungary’s flagship health tourism hubs.

Hévíz Lake Bath redevelopment: why the central building became urgent

The competition follows technical and structural concerns around parts of the bath complex built over the lake. Magyar Építők reports that a section of the over-water structure had to be closed due to structural issues, while the lake itself and other related units continued operating, signalling the need for a long-term, system-level solution.

The over-water bathhouse has a demanding engineering setting: it stands on piles in the lake. The same report notes that the building has been monitored with geodetic measurements since 2008, and a 2023 investigation indicated notable movement in the central section.

A three-phase plan: bath complex, hospital, then tourism upgrades

The design brief breaks the development into three main phases:

Phase 1: Lake Bath Buildings first

Partial demolition, reconstruction and renovation of bath buildings closest to the lake, plus plans for new structures in the immediate spa zone.

Phase 2: hospital-related functions

Reorganising and modernising buildings and functional units linked to the Szent András Rheumatology Hospital.

Phase 3: new tourism attractions

Designing tourism-focused functional units to broaden the visitor offer and overall experience.

Timeline: what could happen in 2027 and 2028?

Termál Online reported earlier that local leaders discussed a timeline in which 2027 would focus on finalising detailed plans and 2028 could be the year when major construction begins, with the project delivered in “blocks” rather than all at once.

A more recent Termál Online update says the jury is expected to announce results by late September, and that after the competition the state would select the designer for permitting and detailed plans. Officials quoted in that report said the selection process could conclude in the first quarter of 2027, followed by around a year for detailed design work. The same update notes that phased demolition and construction could start in the second half of 2027, while keeping the facility operational.
