Many of our most historic buildings and bridges are made from sandstone, so yes, you can build substantial features with it.
However, and there is always a 'however', it depends on the clay content within the rock - sandstone with a high clay percentage will crumble quite quickly when exposed to the elements. So, if you're buying it for construction purposes e.g. if the wall you intend to build is over one metre high where a collapse could injure or kill someone, it would be preferable to get construction quality rock - it usually comes in 'grades'.
For example, Sydney Sandstone is quite famous, but a lot of it has a high clay content so it needs to be quality assured if used in construction.
