seriously, your costings / values / sizes appear grotesquely inflated……..
Your type & size of place goes for maybe 3 mill baht at Phuket Palace Patong, for example.
Build / Equip Cost for your condo design alone cannot realistically be over 1 mill ?
European Luxury Kitchen ( max. 900 k, seriously, for that cramped condo ?), open to Living Room, is not economic for this design……any fancy wooden frame kitchen exposed to salt air / humidity / loose sink water, etc. will likely soon rot away ……again, where is your sound market advice here from the Architect ?
my ground floor two bedroom apartment is architect - measured 80m2 , same function as yours but way bigger bedrooms, living room & (separated) kitchen……
My four level Seaview Hillside Renovated Pool Villa ( Phuket West Coast) 320m2 , semi- detached, end unit, 6 bedrooms, 4 Bathrooms, 2 kitchens, 2 living rooms, four balconies, utility room, parking, sundeck, chill lounge; shared 17 mtr Pool, shared Gardens; would perhaps fetch 12-13 mill baht, including said apartment……..similar enclosed unit, with no work done since 2008 Build, is under Sale now at 11 million baht. Something seriously amiss with accepting / projecting 7-15 mill. baht ?
You can find Luxury Detached Private Pool Villas for 12- 15 mill in Nai Harn / Rawai !! On their own land of course……
You must surely speak ( again ?) with your Architect about True Costs & Values & also Land Office Matters……..
