Ulkoterassit

Ulkoterassit are exterior, open-air living spaces adjoining a building, designed for leisure, dining, and social activity. They can be ground-level patios, raised decks, or freestanding platforms, and may be integrated with the building’s footprint or connected to it by stairs or doors. In Finland and other Nordic countries, they extend the summer living area and are often used for meals, relaxation, and hosting guests.

Construction and design considerations include a substructure with foundations or beams to support load, including snow load in winter. Drainage and slope management are essential to prevent water pooling. Finishes range from timber decking and hardwood to composite decking, stone, or concrete. Safety features commonly include railings for higher terraces and non-slip surfaces, plus lighting, shade structures, and weather protection such as pergolas or windbreaks. Access points, privacy, and integration with surrounding landscaping are also important design factors.

Materials and climate influence durability and maintenance. Nordic climates require materials that tolerate freeze-thaw cycles, moisture, and, in coastal areas, salt exposure. Timber may require sealing or painting, while composites offer lower maintenance at a higher initial cost. Regular maintenance typically includes cleaning, sealing or staining, inspection for rot or corrosion, and winter preparation. Snow removal and de-icing are routine in colder regions to preserve safety and surface integrity.

Regulations and usage vary by country and municipality. Residential terraces enhance living space and outdoor connection to the home, while commercial terraces such as restaurant patios may require permits, setback rules, and adherence to accessibility and safety standards.
