PROBLEM TO BE SOLVED: To provide a barrier-free lean-to roof balcony capable of going in an out of the living room unit side without a floor step difference, by lowering a drainer of the sweeping-out window lower end of an adjacent upper floor building unit, without changing a height of an upper beam of a lower floor building unit, in a unit type building.SOLUTION: In a unit type building having adjacently an upper floor building unit 2 and a lean-to roof balcony 4 on a lower floor building unit 1, the lean-to roof balcony 4 comprises a three-way frame 41 composed of a beam 41a in substantially parallel by separating from the upper floor building unit 2 and a beam 41b substantially orthogonal to the upper floor building unit 2, without a floor beam along the adjacent upper floor building unit 2 side and a floor support body 43 installed in its three-way frame 41 and supporting a floor surface material 45. Actually, the floor support body 43 partially projects under the three-way frame 41, and is positioned inside a ceiling beam 11 of the lower floor building unit 1.SELECTED DRAWING: Figure 1 |
