From understanding regulations to selecting the right design team, we provide the key information to start your project in Costa Rica with confidence and clarity.
What is an Architectural Preliminary Design?

An architectural preliminary design is an initial phase in the architectural design process where the general vision of the project is conceptualized before proceeding with detailed plans and construction. This step is crucial to ensure that all parties involved, including clients, architects, and possibly regulatory authorities, have a clear understanding of the project’s scope and intentions.
Key Features of an Architectural Preliminary Design
Concept Definition:
The fundamental ideas of the project are established. This includes the aesthetic vision, desired functionality, and the primary objectives that the building or structure must fulfill.
Preliminary Studies:
Site analyses, feasibility studies, and evaluations are conducted to ensure that the project is viable in the desired location and under existing conditions.
Sketches:
Visual representations such as sketches and hand-drawn drawings are created to help visualize the space and form of the building. These are crucial for communicating ideas and receiving initial feedback.
Dialogue:
During this stage, effective communication with all stakeholders is vital. This includes discussions on the budget, expectations, and any legal or regulatory constraints that could influence the project.
What Do Plans Include in a Preliminary Design?

Plans in an architectural preliminary design are essential tools that provide detailed information about the proposed design of the project. These plans are fundamental for the visualization, planning, and execution of construction, and their detail and precision can vary depending on the project’s complexity. Below are the typical components included in the plans of a preliminary design:
Site Plans:
These plans offer an aerial view of the land and its surroundings, showing the proposed location of new constructions, access points for vehicles and pedestrians, and the project’s relationship with the existing environment. They include details such as topography, orientation, and natural or built elements that impact the design.

Floor Plans:
Floor plans are diagrams that show the layout of spaces within the building from a top view. They detail the location of walls, windows, doors, and other structural elements, as well as the function of each space, such as rooms, bathrooms, kitchens, and common areas. These plans are fundamental for understanding the distribution and spatial flow of the design.
Elevations:
Elevations are graphical representations of the building’s facades. They show the exterior appearance, including architectural details, construction materials, heights, and decorative elements. These views are crucial for appreciating the architectural design and aesthetics of the project.

Sections:
Sections are vertical cuts through the project that show the relationship between different levels, the height of spaces, and the integration of structural elements such as beams and columns. They provide a clear view of the internal structure and are useful for understanding aspects like natural lighting and ventilation.
Construction Details:
Although in the preliminary design phase the details may be preliminary, some plans include essential information on specific construction techniques or systems, important joints or assemblies, and other technical details crucial for the correct interpretation of the design.
Perspectives and Renderings:
In addition to technical plans, architectural preliminary designs often include visual representations such as perspectives or renderings that offer a three-dimensional view of the project. These help all stakeholders visualize the final product more concretely and in detail.
These plan components ensure that the architectural preliminary design fulfills its role of guiding subsequent stages of design and construction, providing a solid and detailed foundation for the project’s development.
