None of the owners has the right to build on a party wall a building that is intended only for the specific needs of that party, even if the construction is limited to its own side of that party`s property line.8 A party wall serves the mutual comfort and utility of neighbouring owners, and the only restriction on their use by both is that this use will not be detrimental to the other.9 Many owners do not may not be aware. the obligation to maintain structural functions and to separate the fire from party walls. An interesting incident occurred in 2009, when inspectors responded to a complaint about a façade deformation that the façade was common to two cultivated buildings. The interior inspection revealed a 5-inch crack (Figure 1) that had developed along the line, where the party wall was inserted into the façade. Each building was held separately, and the owners could not get an agreement to repair the crack. The separation of the fire was damaged and the collapse of the road front was imminent. As the engineers could not find a solution to stop the development of the reverence, the façade was demolished. A: An owner who cares about the architectural integrity of a party wall during construction may be advised by a certified statistician. The engineer can check the construction plans, all the underlying plans, plans, construction calculations and a physical examination of the wall to recommend if further work is warranted. A serious accident that occurred during the creation of a 15-story loft in Midtown Manhattan illustrates the risk of not exploring the stratified history of the party walls that adjoin a construction site. The steel loft was built around 1926 on land once inhabited by masonry belonging to a group of rental houses cultivated in the 1880s. During the original construction of the frame, the party wall of the adjacent rental house was installed.
This 1880s wall was also propped up to accommodate the deeper basement of the attic. In 2014, the rest of the rental house was demolished and the excavation of a new building began. The basement of this new building was even deeper than the basement of the loft, and an undersubstantiated installation began. It turned out that the contractor did not fully know that he was actually undermining older construction work. While digging, an old, unseg solid pen overturned and collapsed with tragic consequences (Figure 3).
