RESTAURANT BUILDING

The Höllgrotten Restaurant in Neuheim is a protected building of particular architectural, cultural and economic-historical significance. As the only larger tourism-related building in the municipality of Neuheim dating from the late 19th century, it is closely linked to the tourist development of the Höllgrotten caves and to the historical evolution of the site. Its location in a forest clearing at the intersection of historic routes makes the building a defining part of the Höllgrotten ensemble and of the surrounding landscape.

Built in 1889, the building is designed in the “Swiss house style” and is distinguished by its richly articulated architecture. Characteristic features include the partially sunken base level, the decorative half-timbered façades, the hipped roof with cross gables, and the numerous ornamental elements such as profiled window surrounds, decorated corner pilasters and timber embellishments. This architectural quality formed the basis for the careful refurbishment and restoration.

The aim of the works was to safeguard the historic fabric, ensure the long-term usability of the building, and reinforce its distinctive appearance. A key focus was the roof: the existing roof covering was heavily weathered, so the main roof was re-covered with new plain clay tiles, while the roof structure itself was retained and repaired only locally where required. Eaves, verges, dormers and chimneys were carefully restored or reconstructed in accordance with the historic appearance.

The façades were also treated with great restraint and precision. Based on colour investigations, a differentiated colour concept was developed, making the architectural composition of the building more legible again. Timber cladding, shingles, windows, shutters, corner pilasters, belt courses and decorative elements were carefully coordinated in colour. In the base area, unsuitable coatings were removed and replaced with mineral render or repaired sandstone elements.

Particular attention was paid to the handcrafted details. The basement door could be retained and restored despite moisture damage and insect infestation. Threshold, seals, lock and fittings were repaired, replaced or supplemented where necessary, restoring functionality while preserving the door’s aged patina. The windows were also upgraded and integrated into the new colour concept.

A defining element of the restoration was the reconstruction of the numerous decorative timber elements and façade details. Missing or severely damaged ornamental braces, gable decorations and decorative components were reconstructed on the basis of historic photographs and surviving reference details. This allowed the originally representative character to be strengthened again, without artificially overstating its historic appearance.

The restoration demonstrates how conservation-minded care, technical repair and contemporary requirements for use can be successfully combined. The Höllgrotten Restaurant remains preserved as an important part of the historic ensemble and as a building that contributes significantly to both the local setting and the surrounding landscape. At the same time, its history as an early testimony to regional tourism has once again become clearly visible and understandable.
