Research posture

Continue searching. Switzerland has four certified comparable rows after the Kalthaeusern Schutzraum add-on import and needs one more defensible certified row to reach the five-row country-depth threshold.

The bar a Switzerland listing must clear:

Promote only a Swiss row where the public source states a specific transferable bunker, archive bunker, or separately priced Schutzraum component with both price and underground area. Price-on-request bunker pages, bundled house or apartment Schutzraum schedules, and ordinary Keller or Disporäume price lists without shelter identity stay outside certified medians.

Diligence notes

▸ Archived or secondary evidence; current transferability not confirmed

▸ Sale required canton consent under building-right lease

▸ The offered stock units are sold only together and the basement Schutzraum storage room is tenanted; buyer should verify title allocation and lease

▸ New-build double-house brochure separately prices an optional Schutzraum add-on so buyer should verify title allocation whether acquisition is tied to a specific house and civil-defense use obligations

▸ Swiss armasuisse (VBS) public disposal; the partially asphalted access road must be taken over with the purchase; the municipality of Boltigen holds a pre-emption right (Vorverkaufsrecht) which was unresolved at publication; most ex-military objects sit outside building zones so civilian reuse depends on zoning conformity

▸ Location withheld and buyer due diligence required for transfer structure

▸ New-build brochure separately prices a basement Keller Schutzraum cellar line item and buyer should verify title allocation and civil-defense use obligations

▸ House sale includes a small Luftschutzkeller but the source publishes only a whole-house purchase price
