im so happy with our final choice. i like working with 3D conceptwerke so far ! and they are industrial enough for the hubby! they also have creative solutions and are very keen to think outside the box. the creative process is thus very inclusive and we all feel we are collaborating to build a great home. it's not just client and ID , it's more like teamwork. http://www.three-d-conceptwerke.com/ Habit was a very close contender. they are really really great to talk with and very very detailed and helpful. Please do check them out if you are interested. https://www.facebook.com/habit.llp As for The Carpenters at East Coast, very thorough.. but wow, prices shot through the roof. i dont know if this matters but their office was my favourite. sometimes u look at the ID's office to get a feel of what their aesthetics are .http://www.thecarpenter.com.sg/contact.html
