• Climate Adaptation: Global styles (like glass skyscrapers) often rely heavily on artificial cooling. In the Philippines, tropical design principles (passive cooling, shading) are crucial for sustainability and comfort.
• Cultural Relevance: Philippine architecture integrates indigenous concepts (e.g., the spatial fluidity of the Bahay Kubo) and colonial influences (Spanish, American) to create a distinct identity that resonates with local values and history.
• Resource Availability: Local construction often relies on readily available materials (bamboo, concrete) and techniques, whereas global projects might utilize advanced, imported materials and prefabrication.
• Socio-Economic Factors: Designing for the Philippine context requires addressing unique challenges such as rapid urbanization, informal settlements, and varying economic capacities, necessitating resourceful and resilient solutions.

1. Firmitas (Durability/Firmness): The structure must be solid, structurally sound, and capable of withstanding environmental forces and the test of time.
2. Utilitas (Utility/Commodity): The building must serve its intended functional purpose efficiently and comfortably for its users.
3. Venustas (Beauty/Delight): The design must be aesthetically pleasing, engaging the senses and uplifting the human spirit.

• Scale: The perceived size of a building or space relative to the human body. A monumental scale makes people feel small and awe-inspired (like a cathedral), while an intimate scale feels cozy and safe.
• Proportion: The relationship between the dimensions of different parts of a structure to each other and to the whole. Classic examples include the Golden Ratio (approximately 1:1.618), which has been used historically to achieve aesthetically pleasing proportions.

• As Art: It involves creativity, aesthetics, spatial composition, proportion, scale, light, and materiality. It seeks to express ideas and evoke emotional responses. For example, the soaring vaults and stained glass of Gothic cathedrals were designed to evoke a sense of the divine.
• As Science: It demands a rigorous understanding of physics, structural engineering, environmental systems, materials science, and construction technologies to ensure safety and performance. For example, designing a skyscraper requires precise calculations to resist wind loads and manage building sway.

Important: A successful architect must seamlessly integrate these two aspects. A building that is structurally sound but lacks aesthetic appeal may be functional but uninspiring. Conversely, a beautiful building that fails to shelter its occupants or collapses under its own weight is a failure.

• Le Corbusier and the Five Points of Architecture: A foundational modernist philosophy defining the new machine aesthetic. His five points include: 1) Pilotis (lifting the building on reinforced concrete columns), 2) The Free Design of the Ground Plan, 3) The Free Design of the Façade, 4) The Horizontal Window, and 5) The Roof Garden.
• Frank Lloyd Wright and Organic Architecture: A philosophy promoting harmony between human habitation and the natural world. It emphasizes that a building should grow naturally from its site, utilizing local materials, open floor plans, and strong horizontal lines (e.g., the Prairie Style) to integrate seamlessly with the landscape.

• Cultural Identity: Buildings and monuments serve as physical representations of a society's values, history, and aspirations.
  • The Parthenon in Athens embodies the ancient Greek pursuit of democratic ideals and perfect proportions.
  • The Bahay Kubo in the Philippines reflects indigenous wisdom and deep adaptation to the tropical climate.
• Environmental Stewardship: Modern architecture plays a critical role in addressing climate change through sustainable design, passive cooling strategies, energy efficiency, and minimizing ecological footprints.
• Social Equity: Thoughtful urban planning and public architecture can foster community, inclusivity, and accessibility. Well-designed public parks, plazas, and transit systems connect people, while poor design can exacerbate social divides.

• Form: The three-dimensional mass and volume of a building. It defines the boundaries of space and dictates the overall silhouette against the sky or landscape. Form can be rigid and geometric, or fluid and organic.
• Texture and Materiality: The tactile quality of a surface. Rough textures (like exposed concrete or rough-hewn stone) absorb light and feel grounded, while smooth textures (like polished marble or glass) reflect light and feel sleek.
• Light: The most dynamic element. Natural daylighting changes throughout the day, altering the perception of form and texture, and deeply impacting the mood and psychological comfort of a space.

• Edmund Husserl: Founded phenomenology, emphasizing "back to the things themselves" (direct experience).
• Christian Norberg-Schulz: Explored the "Genius Loci" or the spirit of place, arguing that architecture must meaningfully relate to its site.
• Juhani Pallasmaa: Wrote "The Eyes of the Skin," criticizing visual dominance and advocating for multi-sensory architecture (touch, sound, smell).

• Post and Lintel (Trabeated): The simplest structural system consisting of vertical members (posts) supporting a horizontal member (lintel). Used extensively in ancient Egyptian and Greek architecture.
• Arches and Vaults (Arcuated): A curved structure spanning an opening, designed to transfer weight downwards and outwards to supports. Roman architecture perfected this, leading to vaults and domes that allowed for massive interior spaces.
• Cantilevers: A rigid structural element anchored at only one end to a support, allowing for overhanging elements without external bracing. Common in modern architecture (e.g., Frank Lloyd Wright's Fallingwater).

• Form: The primary identifying characteristic of a volume. It is determined by the shapes and interrelationships of the planes that describe the boundaries of the volume.
• Space: The three-dimensional field in which forms and events occur and have relative position and direction. Space is constantly encompassing our being.
• Order: A condition of logical, harmonious, or comprehensible arrangement in which each element of a group is properly disposed with reference to other elements and to its purpose.

• Axis: A line established by two points in space, about which forms and spaces can be arranged in a symmetrical or balanced manner.
• Symmetry: The balanced distribution and arrangement of equivalent forms and spaces on opposite sides of a dividing line or plane, or about a center or axis.
• Hierarchy: The articulation of the importance or significance of a form or space by its size, shape, or placement relative to the other forms and spaces of the organization.
• Datum: A line, plane, or volume that, by its continuity and regularity, serves to gather, measure, and organize a pattern of forms and spaces.
• Rhythm/Repetition: A unifying movement characterized by a patterned repetition or alteration of formal elements or motifs in the same or a modified form.
• Transformation: The principle that an architectural concept, structure, or organization can be altered through a series of discrete manipulations and permutations in response to a specific context or set of conditions without a loss of identity or concept.

• Needs Assessment: Identifying the required spaces, their sizes (areas), and their specific functions.
• Adjacency Requirements: Determining which spaces need to be physically close to one another for operational efficiency (e.g., a kitchen adjacent to a dining area).
• Site Analysis: Evaluating topography, climate, sun path, wind patterns, zoning laws, and existing infrastructure.
• Budget and Schedule: Establishing realistic financial parameters and timelines for the project.

• Public Space: Open and accessible to all, such as plazas, parks, and civic centers. These spaces foster community interaction and civic life.
• Private Space: Restricted access, intended for individuals or specific groups, such as bedrooms, private offices, or gated residential compounds.
• Semi-Public / Semi-Private Space: Transitional zones that buffer public and private realms. Examples include a front porch, a neighborhood park, or a hotel lobby.
• Served and Servant Spaces: A concept popularized by Louis Kahn. Served spaces are the primary areas of function (e.g., living rooms, exhibition halls), while servant spaces contain the supporting infrastructure (e.g., stairwells, mechanical rooms, corridors).
