Architect, Engineer, Drafter...? (Miami/Ft. Lauderdale area)

[Edi C.]

Hi BP community!

I'm looking for experienced insight on my first stage of a project! I have a small SFH in FLL area, located in a 135x50 lot zoned for 2 units. This old neighborhood developed well over the past years and now values are quite higher than just a few years ago. Some of these lots are being converted to two 3-story townhouses per lot. Even though this may seem the future trend, still a few of these lots are already developed to townhouses. It seems to me a big move tearing down the existing house and build two huge townhouses due to the cost. Instead, I'd like to enlarge the existing unit and add a second unit, and keep the units as a rental over the long run.

Which would be the best professional to tackle this layout? An architect, an engineer, a draftsperson? Any companies in the area?

Any suggestion would be really appreciated!

Thanks for reading the post!
