And that's where the difference lies. You need not just an architect, but a "good" architect who will read your thoughts and suggestions "between the lines", whose imagination, erudition, experience, and, importantly, connections, will work for you to not just build a livable home, but will realize the dream ...
An architect might rephrase a banal doorknob, or come up with a bridge design, or a method of concrete formwork for curved surfaces.
An architect processes information from different sources, filters, adds and brings an idea to its realization. An architect creates a scenario for a person's life in his environment. The most successful ones are: Alvar Aalto Hospital, Calatrava Bridge, Saarinen Airport, Marcel Brewer Museum, Peter Zumthor Spa, Frank Geary Museum, Ludwig Mies Van Der Rohe skyscraper, Hans Scharoun concert hall, Luis Baragan's apartment building, Pier Luigi Nervi's structures.

Maintenance of the project from the technical task of the customer, at the stage of design and construction is called author's supervision.
Author's supervision is necessary to monitor the implementation of work on the project agreed with the customer. In fact, the architect defends the interests of the customer at the construction site, so that the contractors worked, not as they like, but as agreed in the architectural working project, estimates, specifications and technical schemes. Author's supervision is necessary to coordinate the architectural working design, engineering section projects, detailing of individual products and structures.

The process begins with the client's assignment, which is spelled out in the contract between the architect and the client.
This is followed by a preliminary design, which reflects the main idea of the project in sketches, plans, visualizations, layouts, videos, etc.
As a rule, an agreed conceptual design is asked to be evaluated. Therefore, it is in the preliminary design that the structural concept, construction and finishing materials are developed. At this stage, an aggregated estimate of the project is prepared.
Full information on the dnc of the project is reflected in the working documentation, developed in conjunction with the design engineer, which is submitted to contractors for detailed estimates.

This distinction indicates that the design architect makes and coordinates the conceptual proposal, while the the project architect performs the working documentation and coordinates with the designers of engineering sections. This approach is effective on projects for large buildings and structures, where more than one architect is involved and a clear hierarchy is built. There is a clear hierarchy of execution according to the agreed preliminary design.
