1. Personality. Meet them in person. How well do they communicate? Is there a rapport between you? Do they talk about their ideas in a way you can readily understand? Do they fill you with confidence?
2. Design. Look at their work. But more importantly, visit one of their buildings. Do you like it? Does it make you feel good? Is it well put together? Make sure it is the kind of architecture you connect with.
3. Reputation. Talk to previous clients. Seek recommendations.
4. Process. If they’re not upfront about timeframes, fees and cost, then it’s time to go elsewhere.
