Methodology for the Evaluation of the Proposal for the Restoration of Small Architecture in Historical Public Spaces: on the Example of the Restoration of Koch's Garden (National Cultural Monument)

The paper addresses the development of a methodology for the restoration of small architecture in historical public spaces protected as monuments. The methodology is demonstrated using the example of an important historical garden, the National Cultural Monument (Koch's Garden). Koch's Garden, which this paper uses to showcase various restoration approaches for small architecture, was established in the 1930s as part of the sanatorium of MUDr. Karol Koch. The sanatorium and its accompanying garden were designed by architects Dušan Jurkovič, Jindřich Merganc, and Otmar Klimeš. The garden, situated on sloping terrain, features a system of terraces connected by walkways, exotic plantings, sculptures, and numerous small architectural elements. The primary goals of the garden's restoration design were to preserve and restore the original features while emphasizing the authenticity and unique character (genius loci) of the place. The small architecture includes a tourist information centre, a swimming pool, and sunbeds. The pool, integral to the garden's original architectural concept, is preserved as a significant central element. Given its status as a typical example of this type of garden, the focus of the contribution is on the pool. The methodology evaluates pool renovation solutions based on five key parameters: authenticity, function, attractiveness, investment, and operation. Using this methodology, five alternatives were identified: 1. an empty pool with a railing, 2. a pool with pool water, 3. a pool with lake water and aquatic flora, 4. a pool with a water film and a gallery below it, 5. a pool with a reflecting surface as part of an amphitheatre, with storage for garden tools. In addition to diagram-based evaluations, these alternatives were assessed by the general and expert public, incorporating a social parameter into the evaluation. The result is a comprehensive evaluation system that can be applied to other types of small architecture in historical public spaces.
