What house can we get from the typical site of 20x30 m of former garden cooperative?

The maximum quadrant space is left for garden with an outdoor swimming pool due to location of buildings in short ends of the area.

Due to locating the buildings in the ends of the site the space in its center is freed up for garden and for swimming pool.
Two buildings (residential and the block with sauna and shed for 2 cars) on the opposite ends of the site are visually connected by the merbau wood fence with the height of ground floor.
