Competition for state forest headquarters – Estonia

### "FUSION" **Architectural Competition for the RMK Ussimäe Office Building** - **Description of the Site Plan and Architectural Solutions:** Our goal was to create architecture that accurately integrates with the context and function of the site. Analyzing both the historical and current urban layout, we concluded that it would be best to fragment the planned development and give it a rural, local character. The modern RMK headquarters, designed with functionality and aesthetics in mind, presents itself as a harmonious fusion of four main volumes, connected by transparent links made of high-quality glass. The building attracts attention with its varied height, where the two-story section intertwines with single-story elements, giving the whole a dynamic and modern character. This concept of building layout allows for both the preservation of the existing landscape value and the introduction of new architectural value, with dimensions adapted to the surrounding environment and the intended function. The building consists of 4 main volumes, visually and functionally connected by glass links. This approach allowed for clear and clean division of functional zones both inside and outside the building. The designed structure is located in the central part of the plot, at a short distance from the existing building, which is planned for later demolition. The garage building is located in the southern part of the plot near the main entrance. Preserving the existing vegetation allowed for the creation of intimate spaces in the form of courtyards, encouraging both outdoor work and moments of rest. Thanks to the use of glass connectors between the main volumes, users of the building are in constant contact with nature and natural lighting. The layout and distribution of functions within the building are the result of analyses presented in conceptual diagrams. In designing the building, we considered plot conditions such as sunlight, surroundings, existing plants to be preserved, and the communication layout. Directly opposite the entrance, we located the main entrance – with a large logo embossed on the wall and 3 flagpoles. The interior of the building has been carefully divided into several zones, aimed at efficient work organization and user comfort. The office area includes both open spaces, conducive to collaboration and dynamic exchange of ideas, and quiet offices that ensure privacy and focus. Additionally, there is a spacious common area dedicated to relaxation and employee integration. Large glazing corresponds closely with the function of the rooms, introducing natural light into the interior and connecting users with the surrounding landscape. The ground floor houses the hygiene-sanitary section with a technical area, which promotes ergonomic building operation. Additionally, in line with the care for employees' health, a gym/fitness area is available, encouraging physical activity. Noteworthy is the internal atrium, cutting through the corridor of the main building's first floor, which, combined with ridge skylights, provides not only natural light to the rooms but also creates a friendly space. The proportions of the buildings, the choice of facade solutions, and the design of the glazing are adapted to the activities both inside and outside the building. A clear functional layout allows for zoning of functions while enabling interaction between different user groups. The surroundings of the building have also been carefully landscaped. Courtyards and terraces provide employees with places to relax, rest, and work outdoors, creating an atmosphere conducive to creativity and efficient work. The entire space is harmonious and functional, oriented towards the needs of users while integrating with the surroundings. **- Description of Structural Solutions, Building Materials, and Finishing, and Energy Efficiency:** The limitation of materials (wood, terrazzo, and greenery) and their consistent and cohesive application has allowed us to create a building with a traditional character but in a modern form. We placed a strong emphasis on eco-friendly solutions in the design. The building's structure is made of wood (a skeletal structure with glued wood elements). The thermal insulation includes mineral wool with a thickness of at least 45 cm for walls and 50 cm for the roof. The ventilated facades and roof are finished with natural wood on a wooden substructure. The facade, maintained in a contemporary style, stands out with natural wood, which dominates both the facades and the roof, giving the building a warm and friendly appearance. The wooden cladding, which we source sustainably, is likely one of the few environmentally friendly roofing options. Wooden cladding is positioned as an ecological alternative to the zinc roofs popularized in recent years. Natural wood is a renewable resource that can be recycled. The production process for such roofing is energy-efficient. Well-protected, it performs well throughout its use, and after the product's life cycle ends, it can be disposed of or recycled in an environmentally friendly way. Wood stores carbon, which plays an important role in reducing carbon dioxide emissions. Wooden cladding is a versatile, timeless building material that works well in both traditional and contemporary architecture. Natural wood cladding offers a range of aesthetic, environmentally friendly finishing options. In most cases, a wood-covered roof does not need to be entirely replaced. If damage is found on a wooden plank roof, only the damaged planks need to be replaced. Besides the warmth and beauty on the outside, wooden cladding is dimensionally stable. Well-protected, it handles tough weather conditions excellently. Wooden roof cladding weathers, which involves a subtle change in color from the original at the time of installation to delicate grays and light brown tones. The color change is an aesthetic, natural process to be savored and celebrated. The building will be equipped with mechanical ventilation with heat recovery and air conditioning, an air-to-water heat pump supported by photovoltaic panels, underfloor heating, and triple-glazed windows. Additionally, windows on the south side of the building will be equipped with solutions to prevent overheating (external blinds concealed in the facade with automatic control). **- Basic Technical Indicators and Room Program in Table Form (Gross Area, Net Area, and Volume):**
