as an architect - its not possible. its not even like software where if you want to put the time in you can create something "over and above" the brief which is better for users. in buildings improving the "UX" (so to say) will take up limited (and expensive) space, add additional material and construction time and hence cost. you can make small wins but the vast majority of crappy spaces are because the developer will simply make more money that way. the real problem imo is market failure - buyers and leasers of space don't understand their own spatial needs or good outcomes so end up buying something spatially poor because its cheaper.
