I has been criticized for making too squarish houses with too few rooms, so in July 2012 I decided to improve the original Tiny Lot House, now the house is even smaller and include also a pool. Kitchen is separated from living-dining while the upper floor plan are 3 rooms accessible via a small hallway. Designed for families of 4 Sims. You can put one single bed in each bedroom, but I recommend putting two beds in one bedroom and use other room for other purposes. This was a spontaneous idea, aka house made without pre-planning.
Lot size: 1×2.
Lot price: $93,010 in base game, $92,579 in Ultimate Collection, $17,636 unfurnished.
House size: 6×12.
Floor area: 128 squares + 12 squares of balconies (excluding 4 squares staircase void).
Pool size: 18 squares.
Expansions needed: none, just base game only.
PS: I do not know how to create such small lots like 1×2. I downloaded them from ModTheSims.info (Mini residential lots by MaryLou).
