This thread is to discuss and understand some of the fine prints and the invisible concepts that are part of a RE buy. recently i have been rolling this concept of residual uds in my mind for sometime. when i talked about this, to a few of my friends, none of them was ready to accept the concept nor were aware. so what could be the actual meaning.. A hypothetical example-- let us say we buy a flat in a complex of 10 grounds..10 grounds x 2400 = 24000 sq.ft..and let us assume there are only 3 bhk say 20 -all of them are 1500.. so if we were to get a uniform uds of 1050..that is around 24000-21000 - where there is aournd 3000 sq.ft left out. now suppose if there is a small park, a gym and all this are part of this complex, but the property owner holds the remaining 3000.. so this becomes a residual uds.. and again i recently came across a highlight of the project and there it was stated that * terrace rights are not retained by the builder.. so in both the cases, in future developments and expansion there is a chance of the builder getting a bigger pie..(if the terrace rights are retained by the builder..) many may argue that it is not the case, but i know of a builder who still holds the terrace rights for the past 10 years and refuses to budge unless the owners of the apartment are willing to pay a tidy sum... just thinking out loud, on this ..will write more later..
