Recently we have been involved in the design processes of a project with a new client. Overall I would say it has been a good experience so far, particularly when the architect's client is pleased and excited about its progress.
What I think contributes to the success is being proactive in finding any issues in design, and suggesting options towards solutions. Since we are remote, this would involve a series of live internet sessions, screen shots with markups, and email communications.
We have sensed with some of the people within this architectural firm some enjoyment in working with us, because we have become the solution, and helped push and develop design to where it is today. We feel very much a part of their team now, and look forward to a long working relationship towards supporting their continued successes.
