Many professionals could impact your project:
Mechanical, Electrical and/or Plumbing Engineer
Kitchen and/or Bath Designer
Other Municipal Authorities
**Not necessarily in that order!**
At the heart of your project, along side you and a good contractor, an architect can assist you with your design and build journey. Take time to find the right team. Knowledgeable, experienced people you like and communicate well with - will be key to a successful project (and process).
