Nice pictures. BDO sloping tiled roof look very good. Nowadays developers are moving towards the metal sheet flat roof. BDO is pricing base on its success in this area. Glenmarie seems to be more value for money though as it is a new entrant there.
Metal roofing very noisy during rain and very hot. Even with glasswool and aluminium foil also cannot solve problem. Nowadays, metal roofs thickness is gauge 34..so very thin. However, metal roof installation is fast,, easy to install and normally won't leak. Rust or no rust over time, that one depend on manufacturer. If the roof is designed with high gradient, then it is ok.
BDO design is for young families as Master bedroom is big and the other 2 rooms upstairs is small.
Glenmarie is DRB Hicom property arm. In Selangor, the most famous one is Glenmarie Temasya and Glenmarie Cove. Quality comparable to Setia and Eco World.
Have to look at specifications and finishings for comparison. Eg. Last time I check is BDO uses asbestos free sheets for its upstairs ceiling for its older phases or they use ceramic tiles instead of 600 x 600 polished tiles. Maybe now they use plaster ceiling.
