When you actually look forward to choosing a firm that you could build an excellent relationship with, your best bet would be architecture firms in Singapore. They would take your brief and help you turn the respective ideas into a reality. They would also look forward to adding their own experience and knowledge for making the project more than you actually imagined.
They would also be using the latest technology for developing detailed plans along with schedules to complete the entire project. It would be pertinent that you should be clear and able to communicate with the architects in an open manner.
