WE DO OUR RESEARCH!

During this initial phase, LETTER FOUR will evaluate both the project’s goals and constraints. This includes existing conditions, project timelines, and city requirements as they relate to the Client’s description of budget and project needs and desires.

LET'S GET CREATIVE.

Conceptual Design

This phase involves the creation of proposed floor plans and interior and exterior features.

We create hand sketches to scale to review with you for comment and approval before completing the project phase.When working with a retail brand we will prepare imagery from complementary and competitive brands, and prepare material and color palettes that work with the brand graphics, aesthetics, and brand mission. It is during this phase that we develop the big idea: What is the overall character and vision for the project and how does it relate to the site and comply with code requirements?

PRICE CHECK!

Preliminary Pricing

We prepare preliminary pricing for each requested option and relative to the project master plan and phasing where applicable.

Pricing is limited to the building structure(s) and does not include site work or landscaping. The pricing provided is based upon a per square foot cost for affected and new square footage areas only.

WE WORK IN 3D.

Schematic Design

This phase involves modeling and drafting the approved hand sketches prepared in the Conceptual Design phase.

If needed for budgeting, we will sign on consults, such as a preferred structural engineer to determine the structural scope of work. We present our clients with 3D model views alongside floor plans, site plans, exterior elevations, etc. in order to secure Client approval of the design documentation before starting the next phase.
