I purchased a condo 11 years ago in Pratunam Grand Diamond. The project consisted of an Hotel Tower A and residential area, condominiums at Tower B.
Today the  G/F to 7/F area is being transformed to a commercial area. 50 % of Parking space is being changed to a Shopping Mall and the 8/F Common area at Tower B is being transformed as public Office !
Can Petchboonma Company limited, owned by the Chaiyapatranun family and the owner of the Hotel at Tower A and the initial Grand Diamond Building company change the area from residential to commercial without consent and value for it’s residents condominium owners ?
Can he take away a labeled common area as his own office property although on purchase it was clearly labeled as common area ?
Hidden upon purchase but claiming today he is the rightful owner of this common area?
Letters to the juristic department, which is a puppet from Petboonma, and to  Petboonma Company limited remained unanswered. FYI Juristic Department management is also on Petboonma’s payroll.
How can we condominium owners, get justice and proceed economically to ensure legality and common sense prevails so that our properties are not transformed to a commercial area against  our will and how can we get back our common area ? How can we recover, once the mall is established , our financial loses due to reduced condominium value,  property degradation and damage, environment degradation, and  increased security treat as a result of a Shopping mall at the transformed parking area.
It has to be noted also that residents, as per condominium act are not allowed to, install any commercial activity  at their residence. Furthermore, residents also are not allowed to have their ordered meals delivered at their doorstep, for security concern.  Petchboonma Company Limited seems to be exempt from this rules as he invites openly the public to enter to visit his office at our residential private building !
How can we get justice ?
