This is the third-annual collection of residences that were created from buildings that formerly served other purposes. The visionaries who dreamed up and created these homes started off with disused and neglected buildings and transformed them into unusual habitations designed for modern lifestyles. Go to CNBC.com to see the homes that aren't listed here:
Some categories of buildings are favorites when it comes to adaptive reuse. Other homes in this collection were made from unexpected structures. Whatever their starting points, the resulting examples of adaptive reuse range from simple and minimal or rustic to contemporary.
Water Treatment Plant
: United Kingdom
Locals call it Tracy Island, for its resemblance to the island base in the 1960s TV series "Thunderbirds," according to an article in This is Kent, but the Lime Works is a 1930s modernist former water-softening treatment plant owned by an antiques shop owner and his partner. This far-out facility shut down in 1942, and in the 1960s the water board planted poplars to hide it as it was considered an eyesore, reports the Sunday Times.
The owners bought the derelict plant in 2005 and began transforming it into a spacious residence with four floors of living space connected by spiral staircases (with the master suite taking up the whole fourth floor), floor-to-ceiling windows, a movie theater and gym, two kitchens, a rooftop swimming pool and another roof terrace, and hilltop views of the surrounding countryside. When the pair was 90 percent finished with the transformation, they decided The Lime Works was too big, and it's listed it with Savills for approximately $4,756,000, down from the January 2012 asking price of approximately $6,046,000.
: Jersey City, N.J.
The 14-acre Jersey City Medical Center originated in 1882 as Charity Hospital, with other buildings added during the Great Depression as a WPA project, but the complex closed down in 1988.
In recent years, the 10 landmark Art Deco buildings have been undergoing transformation into The Beacon apartment complex, including the restoration of marble flooring, chandeliers, plaster and other decorative features. The suite formerly serving as the mayor's office is now a poker room; a theater is used for events and parties, and many other amenities for residents have been added, such as a sun deck with barbecues and a fire pit, an indoor pool and spa and a daycare facility.
: Whidbey Island, Washington
In 2001, the Seattle architecture and design firm SHED completed the transformation of this former barn and adjacent garage structure into a modern yet rustic home that's also a guest house and work space. Many sustainable and recycled materials were incorporated, such as the salvaged cedar of the original barn siding for the interior walls, and salvaged wood beams for countertops and benches. A salvaged clawfoot bathtub and other plumbing fixtures were reused.
: Bondi, Sydney, Australia
This landmark church in Mill Hill near Sydney's center was reconfigured into two luxury apartments by Baker Kavanagh architects. Rather than just redesigning the interior of the church as many church conversions do, the architects added two contrasting contemporary terraces as well as a pool in illuminated blue. It also retains traditional church elements of pointed arch stained glass windows and vaulted beamed ceilings.
: Loegten, Denmark
As the website for the architectural firm C.F. Moeller points out, disused industrial water towers rise from the center of many small towns in Denmark. This residential conversion is one way to address that concern. Starting in 2004 and completed in 2010, C.F. Moeller in collaboration with Christian Carlsen Arkitektfirma transformed this tower into approximately 33,368 square feet of residential space plus 16,145 square feet for mixed use. That includes 21 apartments that were added to the central silo "a bit like Lego bricks," all of which have views of Aarhus Bay. The silo itself contains the elevators and staircases, and its roof is now a shared roof terrace for the resident.
