Top Specs: Everything mentioned in medium specs, a few things change, like, bricks, granite flooring, all teakwood doors and windows or Upvc windows, higher quality granite for stairs, like hassan green or cat's eye costing more than sadrahalli for stairs, SS grills(stainless steel) for stairs, balconies, wood windows or upvc windows, teakwood more costlier than upvc, whether you want floor to ceiling height 9 ft or 12 ft etc etc.
The quality and make of sanitary fittings also matter, like Eros or Jaguar or Hindware or Parryware etc.
Quality of kitchen sink and granite counter top also matters, plus number of 5 Amps and 15 Amps electrical points you are asking for etc.
Myself, as a vastu consultant have attempted my best to guide you, hope it was useful.
Whatever specs you choose you can consult me for vastu compliance if you wish.
