As the land owner has retained 23 sq. ft. of UDS, it belongs to him legally. All the four flat owners enjoy 380 sq. ft. of UDS each. As such, all the five- the four flat-owners and the land-owner - have only undivided share of land with a total extent of 1,733 sq. ft. The share of each is undivided, and not specific, not divided by metes and bounds. In the circumstances, the land-owner cannot legally put up any construction over his 'specific' share of 23 sq. ft. All the four flat-owners may jointly or severally challenge his action.

Dear Sir

Legally he cannot because it is part and parcel of common area.
