Final answer:
To find the architectural firm for his home remodel, Alex can check the floor plan or remodel-related documentation for the firm's name. Alternatively, he can contact the local building permit office or the county recorder's office for records of the architects involved.
Step-by-step explanation:
Alex needs to locate the architectural firm responsible for the plans for his home remodel. To find this information, he could examine the floor plan of the first story of the house. Architects document their designs using floor plans which usually include architectural firm information such as the firm's name or logo. If the floor plan does not include this information, Alex could also check any documentation or correspondence related to the home remodel, as the architectural firm's details are likely to be included.
Moreover, if Alex had worked with a team of architects, they would have developed the design specifying the layout of rooms, doors, and hallways. Often, this information is also on record with the local building permit office or the county recorder's office if the plans were subject to permitting and inspections. Alex could contact these offices to retrieve the necessary information. Additionally, if the remodel was done recently, there could be signage or other documentation at the property itself that identifies the firm involved.
