The design was complicated and required sophisticated and experienced designers, engineers and procurement crews. MAC design listened to all our wish list items, incorporated almost all of them, but offered their own dramatic design inputs and ways to achieve our goals in more cost effective ways - they took our dreams and brought them to life. Many companies we spoke with said they could do anything we wanted. But from the beginning, MAC took the time and effort to develop the true feel for what we wanted, and then meshed that with their own design skills to create a contemporary AND practical kitchen - not simply executing whatever we thought might work or be interesting. We certainly were prepared to pay what it takes to achieve our goals, but MAC inserted reality into the process, often proposing solutions that saved us considerable sums in various areas. All members of the MAC team were dedicated to their tasks, often going the extra mile to get an aspect just right vs. adopting an easy, off the shelf solution. With their experience and contacts, they were even able to have custom items fabricated that were more cost effective than off the shelf. It was touches like these that took the project from nice to over the top and grand! read less
