Urbainia Spaces Sector 151A: Pre-launch pricing insights?

Is Urbainia Spaces' pre-launch pricing in Sector 151A actually better than current market rates? I'm fed up of renting and eyeing an investment. Trying to compare if the 'early bird' discount is real, or if hidden charges later make it a wash. What about total acquisition cost, like stamp duty, PLC, and parking? Any experiences with unexpected costs at possession?
