When Mr Sewadsha from Ghatkopar East purchased five apartments in a housing project in Bhandup he had no idea that the builder had cheated him by selling refuge areas (vacant areas). The reason why the builder could dupe Sewadsha is because there was an error in the plan annexed to the Occupancy Certificate which shows a part of the vacant space as residential flats on 8th and 15th floor of the housing society even though no constructed residential apartment, fit for occupation, exists there.
