If you’re looking for a home that can also help you get your steps in, this Swedish water tower will pique your interest.

The Vaxholm water tower is located on a small island in the Stockholm archipelago, just 20 miles from the Swedish capital. It was built in 1923 by Swedish architect Cyrillus Johansson, who also designed the Museum of Varmland. It has a cylindrical, wedding-cake design, topped by a copper-clad observatory and wind vein by Swedish sculptor Aron Sandberg.

The red brick industrial structure is currently on the market for SEK19.75m via Christie’s International Real Estate and was in service for 50 years before being decommissioned. It was sold to the current owner in 2000 and has undergone extensive adaptive reuse as a four-bedroom home with living spaces set across four levels.

On the first floor is the kitchen, living and dining area with arched brick windows and a soaring 16-ft-high ceiling. Bedrooms are stacked on the levels above as well as a plywood-lined music room.

If you’re afraid of heights, this may not be the property for you, as the fifth and sixth floors are accessed via a narrow spiral staircase. Originally the tower’s water tank, it’s now used to house telecoms equipment – the roof is dotted with antennas from telecoms firms, generating rental income for the owners to the tune of 300 000 SEK per year. A separate studio apartment on the property also creates rental income.

Still, the best views are saved for the top-floor sauna, which looks out across the island to the water beyond.
