Enchanted,

I think you need to understand the differences between what architects, draftspeople and builders actually are and what they offer o the process and completed project!

As an architect myself I can assure you that every dollar you pay is WELL earned and the reason you think it is expensive may be because you don’t understand what you’re getting for your money? I would avoid using a draftsperson as their skills are very limited and the lack of information is generally added into the builders price (eg, you’re paying the draftsperson less but the builder more to resolve vague details. It equals out).

As for builders ‘designing’, this is not part of their training and is generally based on their past experience (weather that be extensive or not). Architects are not builders and builders are not Architects, they are both separate and highly valuable in their own right, and when they work together you will achieve the best result.

My advice, assess your target market before making a decision. Will potential buyers in your area value a highly designed/detailed project? Will it stand out from the rest of the market and sell faster or for a higher figure? Maybe speak to an agent?

I hope this helps :)
