Architectural design of facades, landscaping

The buildings are designed taking into account the difficult conditions of the protected landscape. Pitched roofs made of black metal tiles, light plastered walls, partially lined with natural stone, delicately fit into the forest landscape, look harmoniously against the background of coniferous forest, give a feeling of comfort to people who come to the stadium. Structures - a metal frame with monolithic ceilings. External walls - aerated concrete with plaster and cladding. Covering - metal tile on rafters and lathing. Modern materials are widely used in facade decoration - facade stained-glass systems filled with single-chamber energy-saving double-glazed windows, louvered grilles made of galvanized steel with a multi-layer paint and varnish coating. Warm, ocher colors were used in the decoration of pavilions and technical structures. In order to improve sanitary and hygienic conditions, the project provides for the improvement of the territory adjacent directly to the buildings with the use of tiled paving of sidewalks and playgrounds, arrangement of lawns, flower beds, planting trees and shrubs, installation of small architectural forms with the possibility of using elements of decorative art. The planning marks of the site were taken taking into account the existing surrounding layout and drainage conditions for the planned territory.
