Heliport: Circles and H on the Roof

Helipad: The Circle and H on the Roof
A residence with a helipad on the roof: a circular platform with a diameter of 21 meters, the surface is a light gray non-slip coating, with a large H symbol in the center and a circle of boundary lights, surrounded by downward-sloping safety netting. The helipad is 600mm higher than the rest of the roof, separated from the roof garden by a low stone wall that can be sat on. Next to it is a staircase leading downstairs and a small waiting room. Shot from an aerial oblique angle, showing the helipad, garden, pool, and surrounding landscape. Early morning, with low, slanted light.
Avoid: Square helipad, no separation from other parts of the roof, using fences instead of safety netting, roof cluttered with equipment.

一棟住宅的屋頂設有直升機坪:直徑 21 公尺的圓形平台,表面是淺灰的防滑塗層,中央是一個大型的 H 標誌與一圈邊界燈,四周是向下傾斜的防墜網。停機坪比屋頂其餘部分高 600mm,以一道可以坐的石材矮牆與屋頂花園分隔。旁邊有一座通往下方的樓梯間與一個小型的候機室。從空中斜角俯視,同時看到停機坪、花園、泳池與周邊的地景。清晨,光線低斜。避免:停機坪做成方形、與屋頂其他部分沒有分隔、使用圍欄取代防墜網、屋頂堆滿設備。
