Hi Matty, all squash take up a lot of room and trail, usually to about 3 or 4m, but Harrier is supposed to be more bushy than the varieties I've personally grown. If you are short on space, you can train them up a trellis or strong net etc, but best if that is set at an angle rather than vertical as the fruit become very heavy and can pull the plant away from the support. In the UK we need a pretty good summer to get more than one or two squash per butternut plant, so fingers crossed! The further south you are, the more likely you will get a good crop.
