Newly built lakeside property in Staad: Comfortable apartment with loggia

Project website: https://lakesidestaad.ch/Apartment No. 5Your new home with many qualities – including a view of Lake ConstanceNear the lake in Staad, a new multi-family house with seven condominiums is being built. The seven 2.5-room condominiums are bright, flooded with light, and offer a lot of comfort. The construction standard is high - geothermal heating and a photovoltaic system, as well as an underground garage, enable modern and sustainable living.As soon as you enter the apartment from the stairwell, you feel the bright and spacious elegance of this apartment. The room height of 2.50 meters throughout the apartment, combined with the open connected living and dining room, gives this jewel a particularly pleasant room feeling. In the entrance area, there is a built-in wardrobe with a tinted full-body mirror.On the lake side, there is the living and resting room, which can be perfectly and easily furnished with living room furniture. A floor-to-ceiling window with a sliding glass door allows you to access your exclusive loggia without any obstacles. The loggia is covered with high-quality outdoor parquet flooring. A floor-to-ceiling glazing protects your loggia from the weather. On warm summer days, the glass elements can be opened by a sliding system and can be easily cleaned thanks to this technology. Enjoy the beautiful view towards the nearby Lake Constance.An open designer kitchen with a cooking island separates the living and dining area from each other. The high quality of the kitchen is immediately noticeable. Ample space for cooking, preparation, and storage are just a few of the advantages of this high-quality kitchen. Of course, the worktops are made of granite and the rear wall is clad with glass. The cooking island looks very modern with the Miele extraction system built into the cooktop. A cumbersome extractor hood hanging from the ceiling is no longer necessary. While cooking, you can see from the opposite window, which provides a lot of daylight, into the greenery. Only the highest-quality kitchen appliances from the Miele brand are installed. The large dining area with access to your south-facing balcony completes this room. This balcony is almost fully sunlit throughout the day and is covered with outdoor parquet flooring, just like the loggia.The bedroom is simply beautiful and stylish to furnish. It is very spacious and also has a floor-to-ceiling window with a view of Lake Constance. The same beautiful long-plank oak parquet flooring as in the living and dining room provides a warm and cozy sleeping atmosphere here. If you want to sleep during the day, you can quickly and easily darken the room using the electric shutters, which are available throughout the apartment.The bathroom leaves nothing to be desired. A rain shower or a full bath for relaxation - both are possible. The bathroom has a lot of daylight through a beautiful window. A modern mirror cabinet combined with the glass shower partition and the high-quality tile flooring make the room shine. The room also offers enough space to comfortably place a Miele washing machine-tumble dryer combination. Here, too, the room height of 2.50 meters is noticeable.A perfect apartment for singles or quality-conscious couples.Please visit our website: https://lakesidestaad.ch/wohnunge/wohnung-4-og-rechts?utm_source=immoscout24.ch&utm_medium=url&utm_campaign=redirect-url
