My sister just got her BTO in Seng Kang, and decided to go for a contractor as it is cheaper. To our surprise this contractor, highly recommended by her friend, is fairly young but with more than 10 years of experience, and very engaging. Very please with his service. Price wise is reasonable as my sister did not opt for HDB tiles. He is a contrast from those typical uncle contractor as he is young (early 30s i presume) and provides very practical ideas. As compared to some IDs, they just design without certain practical considerations and advise. if anyone is interested, you may reach him at 92236469
