A portion of a property that overhangs or underlies another property, without any supporting land directly beneath or above it, characterizes a specific type of ownership. This arrangement often arises in terraced houses or apartment buildings where one property extends over a passageway or another dwelling. An example includes a balcony that projects over a neighboring garden or a room built above a shared entryway. This unique ownership can present complexities in terms of maintenance responsibilities and legal liabilities.
The existence of this property structure carries implications for both property valuation and insurability. Securing mortgages and insurance can be more challenging due to the shared structural dependence and potential disputes regarding repairs. Historically, this arrangement developed organically, especially in densely populated areas where space optimization was crucial. Understanding the specific regulations and legal frameworks governing these situations is paramount for property owners and prospective buyers.
