Hi Laura, It sounds like it's a standard size, although the Gap is 1650mm you'll need to add on the size of the posts which would narrow the size of the gate needed So you're probably looking at about a 1500mm wide gate the posts go in to the brick then the gate on to the post If you wish you can have no posts but personally it may look odd with just a gate and hinge in to brick. But it can be done if you wish but may have to me bespoke. Over all it's a easy job to do Hope that helps
