Building design involves collaboration between many disciplines. The key team members include:
Close coordination between the team is vital for successful building design and construction.
Many factors shape the building design process. The architect must balance and optimize these elements:
The building must serve its intended function and meet the needs of occupants. This influences layout, features, access, systems, etc.
Local climate impacts strategies like solar control, ventilation, insulation, and landscaping. Geology affects the structural system.
The building design responds to site factors like shape, topography, orientation, landmarks, and vistas.
Design must comply with applicable zoning laws, building codes, accessibility standards, and regulations.
Project budget and operating costs impact decisions about size, construction, materials, systems, and lifecycle considerations.
Design choices related to style, proportions, materials, details, and finishes determine the building's visual character.
Sustainable design aims to minimize environmental impact through energy and water efficiency, materials selection, and other strategies.
Design may reflect cultural values related to patterns of use, privacy, social interaction, symbolism, and expression.
Accommodating potential changes in use or capacity requires consideration of adaptability in layout and systems.
Weighing and resolving these often competing priorities is the crux of building design.
While every building is unique, most share common structural and functional elements. Understanding these components provides a foundation for building design.
Foundations anchor the building and transfer structural loads through the soil. Foundation types include:
Soil conditions dictate the suitable foundation type.
The structural frame carries gravity loads and resists lateral forces. Frame types include:
The structural bay establishes dimensions for layouts.
Exterior walls enclose and protect the building. Typical wall assemblies include:
Walls must withstand weather and meet insulation values.
Roofs shield the interior from the elements. Roof types include:
Roof design impacts drainage, insulation, ventilation, daylighting, and aesthetics.
Doors allow access and egress while windows admit light and air. Components include:
These openings account for much of a building's character.
Interior elements include:
Interiors support building functions while creating desired spatial effects.
Building services like HVAC, plumbing, electric, lighting, fire protection, communications, security, and vertical circulation enable occupants to successfully use the building.
Throughout history, architects have developed design philosophies and principles to create successful built environments. Understanding these concepts informs contemporary building design.
Marcus Vitruvius Pollio, a Roman architect writing in the 1st century BCE, established three firmitas, utilitas, venustas - meaning the building must be:
This classic philosophy continues to shape architecture today.
A principle most associated with modernist architects like Louis Sullivan and Mies van der Rohe, "form follows function" asserts that a building's form and spatial arrangement should directly derive from and facilitate its function and use. This principle aims to strip away unnecessary ornamentation in favor of functional honesty.
Biophilic design connects building occupants more closely to nature through strategies like natural ventilation, daylighting, plants, natural materials, views of nature, and geometric patterns found in nature. Studies show this approach enhances wellbeing.
Active design promotes occupant health through the built environment. Strategies include encouraging movement through building layouts, providing exercise facilities, using materials conducive to activity, and integrating amenities like showers and bike storage.
Universal design creates accessibility and usability for people of all abilities and ages through elements like step-free entries, wide corridors, lever handles, clear signage, and logical wayfinding. Accommodating a broad range of users enhances convenience and safety.
By thoughtfully incorporating proven design principles, architects can create buildings that beautifully serve user needs while providing delight.
Sustainable architecture aims to minimize the harmful impacts of construction and building operations on the natural environment through smart design strategies.
Getting green building certifications like LEED validates sustainability efforts.
Sustainable design provides many advantages:
Green building is also commonly required for new construction. Sustainability has become an essential aspect of quality design.
Passive approaches optimize building performance through architectural elements like:
Passive techniques reduce reliance on mechanical systems for heating, cooling, and lighting.
Incorporating sustainability early in design allows these strategies to shape the form and function of the building.
The unique needs of different building types require specialized design solutions.
Key considerations for apartments, condominiums, and cooperatives include:
Group housing must meet both shared and private resident needs.
Schools and university buildings prioritize:
Design choices can encourage collaboration and different learning modes.
Hospitals and medical buildings require:
Healthcare design focuses on safety, clinical needs, and emotional wellbeing.
Tailoring form to specialized functions results in effective building design.
Creative selection of architectural styles and materials allows designers to achieve functional and aesthetic project goals.
Architectural styles reflect cultural values and design philosophies of their era through form, features, and materials. Popular styles include:
| Style | Key Features |
|---|---|
| Modern | Simple geometric forms, open floorplans, large windows, minimal ornamentation |
