The purposeful way to develop a niche from nothing is to publish.
One of the best strategies for building a busy, well-paid architectural practice is to develop a niche. The main obstacle for most firms is being recognized as knowledgeable about the niche and therefore considered or sought out for those niche projects.
Publishing on a topic is one of the key tactics in developing a niche and demonstrating your expertise in the project type. Fred Stitt, publisher of Guidelines newsletter and founder of the San Francisco Institute of Architecture, has described the process of developing a niche in his publications. Paraphrasing, these are the steps:
A byproduct of this process is that you will get to know a lot of people in the industry you want to work for and will be in the right place at the right time to find out about upcoming projects. Always ask what they have in development and if they know of anyone else who is planning to do something.
The goal is to know as much as your clients do about their industry, and eventually, to know more so that you are the expert and can ask for a premium. You can imagine other things that you can do.
