柵の梁はちょっと弱いので単管を使いました。
足場組めればいいんですが、そこまでやっちゃうと壁面塗装もやりたくなって、それこそ業者に頼んだほうが良くなりますからねー。

The beams of the fence are a little weak, so I used a tube pipe. I'd prefer to build some scaffolding, but if I went that far, I'd also start wanting to paint the walls, and that's when it becomes better to leave it to a professional.
