In 2000, local architects set about repairing the crypt.
This took away aspects of the unfinished nature of the buildings.
However it did present a more tourist-friendly structure, and now visitors can stand on the roof, what would have been the church floor. 
The "kang" is said to be derived from the concept of a heated bed floor called a "huoqiang" found in China in the Neolithic period, according to analysis of archeological excavations of building remains in Banpo Xi'an.
However, archeological sites in Shenyang, Liaoning, show humans using the heated bed floor as early as 7,200 years ago.
The bed at this excavation is made of 10 cm pounded clay on the floor.
The bed was heated by "zhidi" which is simply the process of placing an open fire on the bed floor and clearing the ashes before sleeping.
It is mentioned by Tang poet Meng Jiao in his poem titled "Handi Baixing Yin".
'No fuel to heat the floor to sleep, standing and crying with cold at midnight instead'.
In the excavated example the repeated burning is believed to have turned the bed surface hard and moisture resistant.
The first known type of heated platform appeared in modern-day Northeast of China and used a single flue systems found in the hypocaust of Ancient Rome and the "ondol" of Korean origin.
An example of this type of heated platform was unearthed in 1st-century building remains in the Heilongjiang Province.
Its single flue is 'L' shaped, built from adobe and cobblestones and covered with stone slabs.
Heated walls with a double flue system was found in a 4th-century ancient palace building in the Jilin Province.
It has an 'L' shaped adobe bench with a double flue system.
It is structurally more complex than a single flue system and has functionality similar to a "kang".
The word "kang" means "to dry", first documented in the Chinese dictionary in AD121.
The earliest "kang" remains have been discovered at Ninghai, Heilongjiang Province, in the Longquanfu Palace (699-926) of Balhae origin.
The "kang" may have evolved to its bed design from earlier developments due to ongoing cultural changes during the Southern and Northern Dynasties, as high furniture and chairs came to be prevalent, over the earlier style of floor-sitting and low-lying furniture in Chinese culture.
Literary evidence from the Shui Jing Zhu also gives evidence of heated floors by the Northern Wei Dynasty, though it was not explicitly named a dikang:Outside China, the concept of a "masonry heater", a large stove made of brick or other masonry keeping a house warm for a long time, has been used in various forms throughout northern and eastern Europe.
In particular, Russians have traditionally used a similar sort of stove/bed, known as the Russian oven (); it is unknown whether this was introduced from the East during the period of the "Tatar yoke". 
Wickland is a three-story mansion considered one of the best domestic Georgian buildings in the commonwealth of Kentucky.
The first and second floors have identical floor plans.
Each has a hall with four well proportioned rooms on each side.
On the first floor the dining room and the library are on opposing sides.
The third floor consists of a front attic and two ample rooms.
The staircase which connects all three floors is cantilevered from the walls, with no visible support.
Originally, the kitchen was separated from the house by an open porch.
It was a two-story building, with the second floor being used by transient workers and as a nursery.
The roof tiles had been replaced four times from its construction in 1815 to 1972.
In the 1930s amenities were added to the house, which included running water, electricity, baths, and furnaces.
Two other buildings are part of the property.
One is a heated outhouse large enough for two rooms.
The other is a two story brick building the Wickliffe family lived in before the construction of Wickland. 
The thirteenth floor is a designation of a level of a multi-level building that is often omitted in countries where the number is considered unlucky.
Omitting the 13th floor may take a variety of forms; the most common include denoting what would otherwise be considered the thirteenth floor as level 14, giving the thirteenth floor an alternate designation such as "12A" or "M" (the thirteenth letter of the Latin alphabet), or closing the 13th floor to public occupancy or access (e.g., by designating it as a mechanical floor).
Reasons for omitting a thirteenth floor include triskaidekaphobia on the part of the building's owner or builder, or a desire by the building owner or landlord to prevent problems that may arise with superstitious tenants, occupants, or customers.
Based on an internal review of records, Dilip Rangnekar of Otis Elevators estimates that 85% of the buildings with elevators did not have a floor named the 13th floor.
Future building designers, fearing a fire on the 13th floor, or fearing tenants' superstitions about the rumor, decided to omit having a 13th floor listed on their elevator numbering.
This practice became commonplace, and eventually found its way into mainstream culture and building design. 
In 1937, the Iowa High School Athletic Association held a single tournament to determine the boys' basketball championship.
Eight larger schools (Class A schools) and eight small schools (Class B schools) were invited to the tournament.
Although the large Class A schools were favored, several small schools won the state championship during this era, including Dunkerton in 1933, Melrose in 1937, and Diagonal in 1938.
Melrose High School did not have a gym for the 1937 team to use or for its home games.
Instead, they used the floor of the town opera house.
The court measured 30 feet (9.14 meters) in width by 40 to 45 feet (12.19 to 13.72 meters) in length.
One corner of the playing floor featured a pot-belly wood stove, which heated the building.
The circles around the foul lines intersected the circle at center court.
The Melrose opera house floor was less than 30 percent the size of the Drake University Fieldhouse floor, where the State tournament was played.
That floor measured 50 feet (15.24 meters) by 94 feet (28.65 meters).
During the 1937 season, the teams had a center jump ball after each score.
This allowed teams, like Melrose, with a tall center to control the tempo of a game.
It would also allow a team that was behind to more easily rally as the players could regain possession of the ball after each basket.
The Iowa High School Athletic Association, like other associations, changed this rule after the 1937 season to its current rule.
The Melrose coach was Adolph "Ad" Hlubek, the school superintendent.
He told people that he learned most of what he knew about coaching basketball from a 10 cent paperback book.
He also said that he learned the sliding zone defense they used from a friend in Kansas.
