It's good to allow about 8 hours from start to finish. We set up the frame of a 5m dome with two people in 7 hours. The cover takes much less time but you will need about 4-5 people to all be there to pull down. Domes above 7 metres will take longer. As with anything doing it for the first time can take longer than you expect but it's fun and extremely rewarding once you have the end product.
