There's nothing wrong with a RE professional knowing about and understanding construction and architecture. Frankly I'm called upon quite a bit because I have the aforementioned credintails and experience.
I think sometimes we need to think a bit more before we speak.
For a buyer it is just as important to have your own agent representing your interests. Their commission is customarily paid for by the seller and a good broker/agent will not only help you navigate the advantages and disadvantages of the properties available but also advise you on negotiation strategies, inspections, etc.
An architect is completely unrelated to brokering a real estate transaction, as they are involved in designing structures. If your question is could there be an advantage to having an architect who is also a real estate broker represent you I can't think of any advantage. In fact generally if a real estate broker is also actively involved in any other unrelated field of employment it is usually difficult them to exceed in real estate. I recommend a full time experienced real estate agent or broker.
If the choice is architect with a broker license versus a reputable, experienced agent/broker who is active in the business, I'd choose the active agent/broker every time. Having knowledge of construction and architecture is great, but you can get inspections for that and you can't replace market knowledge.
