Brand book for architectural application

We are a brand that connects architects with investors. An investor in this context is a person who wants to furnish a house, premises, garden, etc.

-the ability to create an architect's profile, where they can post their portfolio, list of services, opinion and information about the company

-the ability to create an investor's account, where they can add architects to their favorites and track project progress

-chat between the architect and the investor

-notes

-creating a shopping list

-creating schedules and surveys

-the ability to share files

What we are interested in for this announcement is to systematize the graphic system we currently have and turn them into a brand book, in which we would need the following

-specification of the logo (the logo already exists, but we are open to any suggestions and modifications)

-definition of the brand colors

-fonts

-prepare some templates for posts on Instagram
