Build a wheelchair ramp for In-ho in Mapo

In-ho has used a wheelchair since 2023, and the house has three steps at the front door and no ramp. At the moment In-ho can only go outside when two neighbors are available to lift the chair. The materials (treated timber, screws and non-slip surface) have been donated by a local lumberyard. We need a carpenter or two to measure, cut and build, plus a helper or two. The ramp has to meet the local accessibility standard of 1:12 slope, which is why a person with building experience is important. We estimate eight hours of work. Tools are welcome - saws, drills, spirit levels. We'll provide refreshments, and In-ho's family will cook lunch for the team. Please ask me anything in the questions section. I'll answer honestly and quickly.
