Interior space

1. 1. UNIT-I Interior Space
2. 2. SPACE – DEFINITION Space is a prime ingredient in the designer's palette and the quintessential element in interior design. Through the volume of space we not only move; we see forms, hear sounds, feel gentle breezes and the warmth of the sun, and smell the fragrances of flowers in bloom. Space inherits the sensual and aesthetic characteristics of the elements in its field. Space is not a material substance like stone and wood. It is inherently formless and diffuse. Universal space has no defining borders. Once an element is placed in its field, however, a visual relationship is established. Space is formed by our perception of these relationships.
3. 3. ARCHITECTURAL SPACE The geometric elements—point, line, plane, and volume—can be arranged to articulate and define space. In architecture, these fundamental elements become linear columns and beams, planar walls, floors, and roofs. • A column marks a point in space and makes it visible in three dimensions. • Two columns define a spatial membrane through which we can pass. • When supporting a beam, the columns delineate the edges of a transparent plane. • A wall, an opaque plane, marks off a portion of amorphous space and separates here from there. • A floor defines a field of space with territorial boundaries. • A roof provides shelter for the volume of space beneath it. In architectural design, these elements are organized to give a building form, differentiate between inside and outside, and define the boundaries of interior space.

5. 5. EXTERIOR SPACE A building's form, scale, and spatial organization are the designer's response to a number of conditions—functional planning requirements, technical aspects of structure and construction, economic realities, and expressive qualities of image and style. In addition, the architecture of a building should address the physical context of its site and the exterior space. A building can be related to its site in several ways. It can merge with its setting or dominate it. It can surround and capture a portion of exterior space. One of its faces can be made to address a feature of its site or define an edge of exterior space. In each case, due consideration should be given to the potential relationship between interior and exterior space, as defined by the nature of a building's exterior walls. Selecting and developing sites to reduce site disturbance, storm water runoff, heat island effects, and light pollution contribute to sustainable design.

7. 7. Interior space – spatial qualities: form, scale, outlook Upon entering a building, we sense shelter and enclosure. This perception is due to the bounding floor, wall, and ceiling planes of interior space. These are the architectural elements that define the physical limits of rooms. They enclose space, articulate its boundaries, and separate it from adjoining interior spaces and the outside. Floors, walls, and ceilings do more than mark off a simple quantity of space. Their form, configuration, and pattern of window and door openings also imbue the defined space with certain spatial or architectural qualities. We use terms such as grand hall, loft space, sun room, and alcove not simply to describe how large or small a space is, but also to characterize its scale and proportion, its quality of light, the nature of its enclosing surfaces, and the way it relates to adjacent spaces. Spatial Qualities- Entrances mark the transition Form from here to there. Scale Light
8. 8. Spatial Qualities- Form Scale Light Outlook Form Scale Light Outlook
9. 9. Spatial Qualities-Form The design of interior spaces requires, therefore, an understanding of how they are formed by the building systems of structure and enclosure. With this understanding, the interior designer can effectively elect to work with, continue, or even offer a counterpoint to the essential qualities of an architectural space. Continuation Contrast Counterpoint The basic shell … modified architecturally or through interior design
10. 10. Structural Systems A building's structural system is formed according to the geometry of its materials and the way they react Roof structure to the forces applied to them. Rafters This structural form and geometry, in turn, influence the Columns dimensions, proportion, and arrangement Bearing wall of the interior spaces within the building volume. Floor structure superstructure is the vertical extension of Beams the foundation system and consists of the columns, beams, and load-bearing walls that support the floor and roof structures. The foundation system is the substructure that forms the base of a building, anchors it firmly to the ground, and supports the Foundation wall building elements and spaces above. Types: Footing Linear Structural Systems Planar Structural Systems Volumetric Structural Systems
11. 11. STRUCTURING SPACE Enclosure System Roof • The building envelope consists of exterior walls, windows, doors, and roof, which protect and shelter interior spaces from the exterior environment. Exterior Doors and windows • walls Interior walls, partitions, and Partition ceilings subdivide and define interior space. Many of these components are nonstructural in nature and carry no loads other than their own weight.
12. 12. VOLUMETRIC STRUCTURAL SYSTEMS A volumetric structural system consists of a three-dimensional mass. The mass of the Three-dimensional material occupies the void of space. space Out of the mass is carved the volume of interior space. At a small scale, stone and clay masonry units Three-dimensional can be seen to be volumetric structural form elements. At a larger scale, any building that encloses interior space can be viewed as a three- dimensional structure that must have strength in width, length, and depth. Composite systems combine linear, planar, and volumetric elements into three- dimensional compositions of form and space. Walt Disney Concert Hall, Los Angeles, California, Frank Gehry, 2003
13. 13. SHAPING INTERIOR SPACE WITH INTERIOR DESIGN ELEMNETS Although a building's structural system sets up the basic form and pattern of its interior spaces, Ceilings these spaces are ultimately structured by the Partitions elements of interior design. The term ―structure‖ is not used here in the sense of physical support. It refers to the selection and arrangement of interior elements Furniture such that their visual relationships define and organize the interior space of a room. Non-load-bearing partitions and suspended ceilings are often used to define or modify space within the structural framework or shell of a building. The color, texture, and pattern of wall, floor, and ceiling surfaces affect our perception of their relative positions in space and our awareness of the room's dimensions, scale, and proportion.

15. 15. SHAPING INTERIOR SPACE Within a large space, the form and arrangement of furnishings can divide areas, provide a sense of enclosure, and define spatial patterns. Lighting, and the light and dark patterns it creates, can call our attention to one area of a room, deemphasize others, and thereby create divisions of space. Color, texture, and pattern Even the acoustic nature of a room's surfaces can affect the apparent boundaries of a space. Soft, absorbent surfaces muffle sounds and can diminish our awareness of the physical dimensions of a room. Communication Hard surfaces that reflect sounds within a room help to define its physical boundaries. Echoes can suggest a large volume. Finally, space is structured by the way we use it. The nature of our activities and the rituals we develop in performing them influence how we plan, Movement arrange, and organize interior space.
16. 16. SPATIAL FORM Interior spaces are formed first by a building's structural system, further defined by wall and ceiling planes, and related to other spaces by windows and doorways. Every building has a recognizable pattern of these elements and systems. Each pattern has an inherent geometry that molds or carves out a volume of space into its likeness. It is useful to be able to read this figure-ground relationship between the form of space-defining elements and that of the space defined. Either the structure or the space can dominate this relationship. Whichever appears to dominate, we should be able to perceive the other as an equal partner in the relationship.
17. 17. It is equally useful to see the alternating figure ground dominance occurring as interior design elements, such as tables and chairs, are introduced and arranged within an interior space. When a chair is placed in a room, it not only occupies space, it also creates a spatial relationship between itself and the surrounding enclosure. We should see more than the form of the chair. We should also recognize the form of the space surrounding the chair after it has filled some of the void. As more elements are introduced into the pattern, the spatial relationships multiply. The elements begin to organize into sets or groups, each of which not only occupies space but also defines and articulates the spatial form.
18. 18. SPATIAL DIMENSIONS-Scale The dimensions of interior space, like spatial form, are directly related to the nature of a building's structural system—the strength of its materials and the size and spacing of its members. The dimensions of a space, in turn, determine a room's proportion and scale and influence the way it is used. One horizontal dimension of space, its width, has traditionally been limited by the materials and techniques used to span it. Today, given the necessary economic resources, almost any architectural structure is technically possible. Wood or steel beams and concrete slabs can span up to 30 feet (9 m). Wood or steel trusses can span even farther, up to 100 feet (30 m) or more.
19. 19. structure space frame Longer roof spans are possible with space frames and a variety of curved structures, such as domes, suspension systems, and membranes supported by air pressure. Within the bounds of structural necessity, the width of an interior space should be established by the requirements of those who use the space and their need to set boundaries for themselves and their activities. Building designers have traditionally developed membrane for tensile structures spatial relationships by sketching and model building. Computer aided design (CAD) and building information management (BIM) software systems are changing the way that building designers work. These computer technologies allow designers to build interactive three-dimensional computer models frame supported dome of buildings, and to coordinate building systems as tensile structure
20. 20. SQUARE SPACES The other horizontal dimension of space, its length, is limited by desire and circumstance. Together with width, the length of a space determines the proportion of a room's plan shape. A square room, where the length of the space equals its width, is static in quality and often formal in character. Pyramids, domes, and similar roof form The equality of the four sides focuses our can emphasize the centrality of square attention in on the room's center. spaces. This centrality can be enhanced or emphasized by covering the space with a pyramidal or dome structure. To deemphasize the centrality of a square room, the form of the ceiling can be made asymmetrical, or one or more of the wall planes can be treated differently from the others. The placement of architectural elements, such as windows and stairways, can deemphasize the centrality of square spaces.
21. 21. Rectangular space Square rooms are rare and distinctive. More often, a room will have a length greater than its width. A rectangular space, normally spanned across its width, is eminently flexible. Its character and usefulness are determined not only by 1:1 1:2 1:3 Its proportion of width to length, but also by the configuration of its ceiling, the pattern of its windows and doorways, and its relationship to adjacent spaces. When the length of a space is greater than twice its width, it tends to dominate and control the room's layout and use. Given sufficient width, the space can be divided into a number of separate but related areas. A space whose length greatly exceeds its width encourages movement along its long dimension. This characteristic of linear spaces makes them suitable for use as gallery spaces or as connectors of other spaces. Horizontal dimensions alone do not determine the ultimate qualities and usefulness of a space. They only suggest opportunities for development.
22. 22. Both square and rectangular spaces can be altered by addition or subtraction, or by merging with adjacent spaces. These modifications can be used to create an alcove space or to reflect an adjoining element or site feature. Extension Addition Subtraction Merging Altering Space
23. 23. Curvilinear spaces The nature of building materials and the techniques used to assemble them have established rectangular spaces as the norm. Curvilinear spaces are exceptional and usually reserved for special circumstances. The simplest curvilinear space is a circular one. It is compact and self-centering. The radius of the curvature of a Although it creates a focus on its center, a circular space also relates to the surrounding space equally wall depends on the scale and in all directions. flexibility of the material used to It has no front, back, or sides, unless these are build it. defined by other elements. An elliptical space is more dynamic, having two centers and unequal axes. Other curvilinear spaces can be seen as transformations of circular or elliptical spaces that have been combined in an overlapping manner. The use of three-dimensional computer modeling is increasing the ease of designing complex curves.
24. 24. Circle Ellipse Freeform Furnishings may be placed as freestanding objects within a Circular space serving ascurvilinear space or be integrated an organizing element within the curved forms. Walls curving to respond to an exterior condition
25. 25. THE VERTICAL DIMENSION OF SPACE(HEIGHT OF SPACE) The third dimension of interior space, its height, is established by the ceiling plane. This vertical dimension is as influential as the horizontal dimensions of a space in forming the spatial quality of a room. While our perception of a room's horizontal dimensions is often distorted by the foreshortening of perspective, we can more accurately sense the relationship between the height of a space and our own body height. A measurable change in the height of a ceiling seems to have a greater effect on our impression of a space than a similar change in its width or length. Varying the ceiling height can have a powerful effect on the perceived scale of a space.
26. 26. CEILINGS High ceilings are often associated with feelings of loftiness or grandeur. Low ceilings may connote cave like coziness and intimacy. However, our perception of the scale of a space is affected not by the height of the The roof structure can ceiling alone, but by its relationship to the sometimes be left width and length of the space as well. exposed, giving A ceiling defined by the floor plane of the texture, pattern, and depth to room above it is typically flat. the ceiling plane. A ceiling created by a roof structure can reflect its form and the manner in which it spans the space. Shed, gable, and vaulted ceiling forms give direction to space, while domed and pyramidal ceilings emphasize the center of a space.

27. 27. SPATIAL TRANSITIONS How interior spaces are related to one another is determined not only by their relative position in a building's spatial Openings within Wall Planes pattern, but also by the nature of the spaces that connect them and the boundaries they have in common. Floor, wall, and ceiling planes serve to define and isolate a portion of space. Of these, the wall plane, being perpendicular to our normal line of sight, has the greatest effect as a spatial boundary. Communication It limits our visual field and serves as a barrier to our movement. Access Openings created within the wall plane for windows and doorways reestablish contact Day lighting with the surrounding spaces from which the and views room was originally cut.
28. 28. DOORWAYS Doorways provide physical access from one space to another. When closed, they shut a room off from adjacent spaces. When open, they establish visual, spatial, and acoustical links between spaces. Large open door ways erode the integrity of a room's enclosure and strengthen its connection with adjacent spaces or the outdoors. The thickness of the wall separating two spaces is exposed at a doorway. Doorway locations affect our This depth determines the degree of separation we patterns of movement sense as we pass through the doorway from one and activities within a room. space to another. The scale and treatment of the doorway itself can also provide visual clues to the nature of the space being entered. The number and location of doorways along a room's perimeter affect our pattern of movement within the space, and the ways we may arrange its furnishings and organize our activities. The widths of door openings affect the ease of movement
29. 29. The number and location of doorways along a room's perimeter affect our pattern of movement within the space, and the ways we may arrange its furnishings and organize our activities. The widths of door openings affect the ease of movement for people and furnishings. A 36-inch (914-mm) wide doorway is reduced to about 32 inches (813 mm) when the thickness of the open door and that of its hardware are taken into consideration. Clear openings of less than 32 inches (813 mm) become barriers to standard wheelchairs, affecting accessibility, visitability, and aging-in-place.
30. 30. WINDOWS Windows let light and air into the interior spaces of buildings and provide views of the outdoors, or from one space to another. Day lighting Framing views Their size and placement, relative to the wall plane in which they occur, also affect the degree of separation between an interior space and the exterior environment. Degree of enclosure …or transparency Views to the outside and natural ventilation are important elements in sustainable design. Windows framed within a wall plane attract our attention with their brightness and outlook but maintain the enclosure Thin frame Thick frame provided by the wall. Large windows and glass walls attempt, at least visually, to merge indoor and outdoor Interior windows …Connecting spaces space.
31. 31. The visual treatment of the window frames in each case can either emphasize or minimize the perceived limits of interior space. Interior windows can, in a similar manner, visually expand a room beyond its physical boundaries and allow it to become an integral part of the surrounding interior space.
32. 32. STAIRWAYS Stairways are also important forms of spatial transitions between rooms. Exterior entrance An exterior set of steps leading to a building's entrance can serve to Public approach Private access separate private domain from public passage and enhance the act of entry into a transitional space such as a porch or terrace. Inviting landings Overlooks Entrances without steps support visitability and aging- in-place. Ascent Descent

The manner in which they perform this function shapes our movement in space— how we approach a stairway, the pace and … Defining an edge style of our ascent and descent, and what we have an opportunity to do along the way. Filling space Wide, shallow steps can serve as an invitation, while a narrow, steep stairway As sculpture may lead to more private places. Landings that interrupt a flight of steps can allow a stairway to change direction and give us room for pause, rest, and outlook. The space a stairway occupies can be considerable, but its form can be fit into an interior in several ways. It can fill and provide a focus for a space, run along one of its edges, or wrap around a room. It can be woven into the boundaries of a space or be extended into a series of terraces.
