When the Penteli town plan began to take form, the claims increased, both in volume and intensity. Courts began to vindicate individual and association claims with a legal base of "good fidelity", and "usucaption". Vrilissia kept expanding into the hill, while it saw losses from each of its sides from the neighbouring suburbs of Melissia, New and Old Penteli. Around this time and in stark contrast to the lower-density provisions afforded for the Ano Vrilissia settlement below the Anapafseos Avenue, the hill was allowed multi-floor apartment blocks (up to five levels), in the process compromising the aesthetics of the Penteliko scenery.
