I am a competitive tennis player and I would like to build a cement wall (like those ones at parks and such) that I can hit against in my backyard. Is that legal and how much would it cost?
firstly to build a wall is classed as a non-tempory construction so you will probably have to ask your town mayer or local council if you can put one up first. and for a brick wall covered in cement would cost around ?35 per square metre. If you do decide to put one up try shaving one side of the tennis ball and then play around with that i have done this in the past when playing against my house wall and the idea behind it is so that it puts a spin on the ball and makes it change direction more so that you don't know where its going to come from which i think makes it a bit more fun and challenging.
