It’s a 2,000 square foot structure built in the middle of a 20 acre land surrounded by a forest
The 2,000 square feet (185.8 square meters) Helmer’s Castle features a 60-foot (18.2 meters) tower with a spiral staircase, a number of fireplaces, shake-style metal roofing, hardwood floors, as well as a half-mile driveway leading up to it. As for the living spaces, it has 5 bedrooms, 3 bathrooms, a kitchen and dining area, expansive living and great room, and a walkout master suite, among many other things.
The luxury doesn’t stop here as there’s also a lighted basketball court outside, 3 separate patios, as well as a number of scenic walking, running, sledding, and exploring trails, all spread across a 20 acre bit of land (almost 81,000 square meters).
Good that you are finally getting on board with the metric system, but the word metre is not spelt meter.
A meter is a gauge, like a speed-o-meter, or an electrical meter.
A metre is 1000 millimetres, a thousandth of a kilometre.
