The guard tower and house need to be split into separate ints with the house being remade as a standard residence (De_p or de_m, claimants choice) following the convention for ex_hlaalu_b_27. The guard tower is somewhat lacklustre in comparison to the others around the city and could use additional cluttering.
Both will need path-grids.
Shells: Tower, ex_hlaalu_b_15. House, ex_hlaalu_b_27
