TECHNICAL FIELD
In particular this invention relates to an adaptable modelmaking system using space defining modules to design buildings.
BACKGROUND
Physical models are sometimes used during the building design process to test or communicate ideas or for final presentation and marketing. Many people are not skilled at drawing or imagining objects and have difficulty visualising 3D buildings from elevations and floor plans. An accurate wellmade physical model provides a better perspective than drawings or computer generated 3D modelling images which try to give the illusion of three dimensions on a two dimensional surface. For this reason, 3D modelling images are not easy to relate to and can be difficult to understand. However, while physical models are easier to comprehend, they can be costly to produce, difficult to modify, and being single purpose will probably be discarded afterwards.
In addition to single purpose model buildings used by professional designers various demountable and reusable construction kits are commercially available mainly for hobbyists and children's toys. There are 3D puzzle model building kits, which cannot be modified, made up of interlocking parts, producing a single purpose model, usually a souvenir of a famous building or building type. There are also other kits which are multipurpose, and modifiable, and concerned mainly with how to connect the parts. One kit uses very small hollow plastic bricks connected by tubular studs with which the user can create somewhat unrealistic models of almost anything. Another kit with a modern design approach has modular floor, wall, and roof pieces which require connection by pegs in holes.
At present there are opposing schools of design amongst building design professionals. Modernists ‘start with the floor plan, and work from the inside out’ emphasising internal layout based on functional requirements which may change over time, whereas traditionalists favour ‘roof plan down, and working from the outside in’ emphasising the more permanent parts of the building such as the structure and ‘skin’.
Contemporary buildings are conceived mainly as highly specialised finished products rather than an activity that changes over time with the needs of the user. At present there are many specialised types of buildings including residential, commercial, industrial, health, education, and religion which are designed ‘not’ to adapt to change even though usages in and around them are constantly changing. All buildings grow and go through many changes during their life cycle and finally completing a new building is an illusion because no building works well in the beginning. The more specialised they are the more difficult they are to reshape. Every building is gradually transformed by the people who occupy them over time. Everyone has their own ideas and sometimes the expensive improvement is worse than what it replaced. Bad design decisions can adversely affect future growth and lifespan. Low roof eaves and concealed roof trusses inhibit horizontal and vertical growth and complexity greatly increases construction and maintenance costs, flat roofs tend to leak, fixed internal walls may be difficult to relocate and services may be hard to access. The building trades use design for demolition trade practices instead of recycling and reuse, generating a large solid waste burden at demolition, meanwhile the building owner is encouraged to borrow money to build more now and pay a lot more later on as interest and to cover construction cost blowouts and excessive claims due to construction changes. On top of all this the maintenance, operating costs and changes made during a buildings lifetime could cost several times more than the original building cost.
Change in buildings is inevitable and different parts change at different rates. Floor plans change most frequently especially in commercial buildings. Services such as electrical, plumbing, heating and ventilation, air conditioning and lifts, change less frequently, whereas the structure and building envelope are least subject to change.
The contemporary approach contrasts with vernacular or traditional buildings where plans are not required and buildings are designed to grow incrementally, room by room, as circumstances permit, with modest multipurpose spaces and connectively between rooms.
This invention is concerned mainly with the building shell, using a small unit as the design and plan module to create designs which are pleasant to be in, adaptable, practical and economical to maintain, relying on natural lighting and ventilation, passive heating and cooling, easy to build in stages, add on to and expand, fully utilising the enclosed volume under the roof, providing general purpose space, standardised rooms and relocatable interior walls where possible and encouraging self-help and community participation in the design and construction process, making buildings more affordable.
Generally a design concept is required before a model can be made, but this invention allows the user to experiment, design a building and make a model at the same time. The model can be easily modified as the design evolves enabling the user to visualise the next stage by what is already there and to study multiple design options. Finally, the model can be quickly disassembled for future reuse. Instead of “making a model based on a design” the user can “make a design based on a model”.
SUMMARY
A modelmaking system for designing buildings in accordance with this invention comprises:
(a) A parts library apparatus including a plurality of individual three dimensional box like space defining forms representing modest room sized units, each unit complete with a square or rectangular floor, walls at right angles to the floor, and a roof with a shape selected from the group consisting of a flat shape, a lean-to shape, a gable shape, a hip shape, a valley shape, and a cross shape, and a roof pitch selected from the group consisting of very low pitch, low pitch, medium pitch, high pitch, and steep pitch, the units may be further categorised as either room units, with optional flat or raking ceilings, very low to medium pitched roofs, and full height walls at least one storey high, or loft units with raking ceilings and medium to steep pitched roofs, the lowest parts of which connect either to short walls or directly to the floor on at lease on side or corner;
(b) Three types of unit assembly of which
- (1) Is a non-core unit assembly of maximum height one and a half storeys in which the lowest part of the roof is about one storey or less above ground level on at least one side of the assembly;
- (2) Is a core unit assembly in which the external walls are at least sufficiently high all the way around to easily accommodate non-core add-on units and non-core extension units by wall to wall surface contact;
- (3) Is a combination of core and non-core assemblies; and
(c) A kit of parts comprising a plurality of at least one type of unit selected from said parts library and assembled by a user in accordance with at least one of said three types of unit assembly to produce at least one model building and building design.
Preferably the modelmaking apparatus may further include part room sized units including quarter, half, and three quarter sized units, and larger room sized units including one and a half and two and a quarter sized units, which are vertical subdivisions and multiples respectively, of the basic horizontal module, the modest room sized unit to give greater flexibility in room size and shape.
Preferably the modelmaking apparatus may further include a flat full room height extender unit with variable height short walls representing wall heights ranging from about 0.6 metres to about 1.5 metres, to enable increased wall and ceiling heights, suspended ground floor support, split levels, roof continuity and the adjustment of room proportions while minimising the proliferation of individual unit types.
Preferably the modelmaking apparatus may further include the following parts library units with alternative additional features comprising:
- (a) a half room unit with a diagonal wall and a room unit with a curved quadrant wall in the flat roof category;
- (b) a half gambrel compound roof loft unit in the lean-to category together with related compound roof loft units in the hip and valley roof categories;
- (c) a low pitched diagonally truncated cuboid loft unit in the lean-to category and a diagonally truncated cuboid room unit in the gable category;
- (d) pyramid, half pyramid, and truncated pyramid room units with polygon bases in the quarter pyramid hip roof category;
- (e) units with gable roofs intersecting lean-to roofs in the cross roof category.
Preferably the modelmaking apparatus may further include units with roofs categorised as curved, the group comprising: a barrel loft unit, a segmental arch room unit, a pointed arch loft unit, a lean-to loft unit, and a quadrant lean-to loft unit, whereby the curvatures in loft units provide increased headroom compared to pitched roofs.
The modelmaking apparatus may further include a range of dormer window roof accessory units for medium to steep pitched roofs with roof shapes selected from the group containing a flat shape, a gable shape, a lean-to shape, a hip shape, and a curved shape.
Preferably the modelmaking system is modular with the horizontal module in plan represented by the modest room sized unit for smaller buildings and a structural bay for larger buildings and the vertical module in section and elevation represented by a modest floor to floor height of one storey.
Possibly, the size of units for a scale model could be about one fiftieth full size with the basic horizontal module representing an average width or length of about 3.6 metres which could be scaled up and down to represent a range of full size room widths or lengths starting at about 2.4 metres and increasing in 300 mm increments up to about 4.5 metres or more, with structural bay sizes approximately double those sizes. The vertical module could remain substantially constant with an average height of about 2.7 metres. A modest size room could be in the approximate range of eleven to fourteen square metres.
The approximate roof pitches range from very low, about five degrees; to low, about fifteen degrees; to medium, about thirty degrees; to high, about forty five degrees; to steep, about fifty five degrees.
Preferably the units are hollow box like forms with wall openings for windows, doors, and other apertures which may vary on different sides whereby the assembled units could be horizontally rotated to reveal alternative exterior openings thus minimising the number of unit types.
In use, in the assembled condition the independent free standing units are unconnected, contiguous and able to be stacked horizontally wall to wall and vertically from ground or base level one on top of the other up to roof level, whereby the units have the capacity for easy demountability, disassembly and reuse.
In a combination unit assembly a non-core add-on unit can be defined as having at least part or all of its roof sloping down and away at right angles from a core wall it abuts whereas a non-core extension unit which projects out at right angles from a core assembly can be defined as having a roof which slopes down parallel to said core wall.
A plurality of non-core add-on units can partially or completely surround a core assembly whereas non-core extension units cannot, and if an add on assembly or extension assembly is above one and a half storeys high it becomes a core add-on or core extension and forms part of said core assembly.
The unit floors and walls inside an assembled model building represent a modular grid of aisles and bays with load bearing columns at or near the internal corners of units but they do not necessarily determine the actual placement of walls, floors, columns, and beams and may be used as a guide for the intended structure and floor plan arrangement. Large span trusses may be required to replace beams and columns where unobstructed open space is required.
Roofs of units are shown without overhangs although they are permitted and depending of the purpose of the model and how the units are made they can be incorporated as an additional feature.
Units may be manufactured by lasercutting wood, plywood, metal, cardboard, paper and foam, or by plastic injection mould or 3D printing. The actual full sized building based on the model could be made of whatever material and construction system is deemed appropriate and possible materials could include bamboo, wood, mud, stone, brick, metal, glass, and concrete.
Possibly the assembly and the parts thereof are provided in the form of virtual entities in a computer program whereby the same process of design using an adaptable model can be performed on a computer.
A method of designing buildings using a modelmaking system comprising:
- (a) Providing a parts library apparatus including a plurality of individual scale model three dimensional box like space defining forms representing modest room sized units or structural bays, each complete with a square or rectangular floor, walls at right angles to the floor, and a roof with a shape selected from the group containing flat, lean-to, gable, hip, valley and cross, and a roof pitched selected from the group containing very low, low, medium, high, and steep, the units being further categorised as either room units, with optional flat or raking ceilings, very low to medium pitched roofs, and full height walls at least one storey high, or loft units with raking ceilings and medium to steep pitched roofs, the lowest parts of which connect either to short walls or directly to the floor on at least one side or corner;
- (b) selecting a plurality of at least one type of unit from the parts library to be defined as a kit of parts;
- (c) deciding on whether to assemble the kit of parts by physical model, computer, or hand drawing;
- (d) providing three types of unit assembly of which:
- (1) is a non-core unit assembly of maximum height one and a half storeys in which the lowest part of the roof is about one storey or less above ground level on at least one side of the assembly;
- (2) is a core unit assembly in which the external walls are at least sufficiently high all the way around to easily accommodate non-core add-ons and extensions by wall to wall surface contact;
- (3) is a combination of core and non-core assemblies and
- (e) Using at least one of the three types of unit assembly to produce at least one model building and building design.
OBJECTS AND ADVANTAGES
- (1) A user friendly system to make to the design process of ordinary buildings easier, quicker and more accessible to anyone. Drawing ability or knowledge of computer draughting is not necessary.
- (2) A straight forward scientific and educational process which can improve the users' imagination, aesthetic appreciation and problem solving skills.
- (3) Depending on the types of units selected by the user, designs can range from simple to complex, for example, from a simple single storey building of prismatic shape using a small variety of units and few rooms with either a flat, lean-to, or gable roof to a complicated multi storey building with add-ons and extensions and many rooms made from a large variety of units and a multi pitched roof using hip, valley, cross or curved shapes.
- (4) Although the model buildings are modular with many apparent joints it is not necessary for the proposed full size building to be modular or to have exposed joints.
- (5) The modular nature of the units allows for easy exploration of alternative design possibilities.
- (6) The space plan and services can be worked out while the model is evolving or after the shell has been finalised using the grid of room sized units as a guide.
- (7) Many contemporary buildings are very wide, relying on artificial lighting and air conditioning. This system encourages narrower building wings, roof lights, courtyards, natural lighting and cross ventilation.
- (8) To further personalise design outcomes custom made forms can be specially designed to be combined with units from the parts library which is non exhaustive.
- (9) The individual units and the three types of unit assembly are designed to allow a building to grow incrementally room by room making it easy to construct a building in stages while looking complete at each stage.

DESCRIPTION OF EMBODIMENTS
FIG. 9A and FIG. 9B are prior art examples of past and present building practices respectively. FIG. 9A is a historic building with suspended wooden floor, high walls, high flat ceiling and medium pitch hip roof flanked by lean-to additions, which may restrict natural light and ventilation into the main building. This building could possibly be lifted, relocated and recycled but it has unnecessarily high walls and ceilings and the enclosed roof space is wasteful. FIG. 9B is a cross section of a contemporary building with a hip roof, of minimal wall and ceiling height and low overhanging eaves making outward expansion difficult and expensive whilst unnecessary large span trusses between the low pitch roof and flat ceiling prevents easy upward expansion into the wasted roofspace. The concrete floor slab prevents relocation, lifting or recycling.
FIG. 10A to FIG. 12 gives an overview or summary of how this invention works and how units can be combined and reconfigured to produce various alternative options.
FIG. 10A shows four quarter pyramid low pitch hip roof room units 68 combined to form a non-core building with a pyramid roof and low eaves all the way round making it difficult to add onto.
FIG. 10B shows four lean-to low pitch room units 56 combined to form a non-core gable roofed building with low eaves on two sides allowing it to be easily extended on two ends only.
FIG. 10C shows four flat room units 50 combined to form a two storey core building with high roof eaves making it easy to add onto all the way around.
FIG. 10D combines all twelve room units from FIG. 10A, FIG. 10B and FIG. 10C to form a core/non-core assembly in which the dominant two storey core units 50 are flanked by non-core lean-to add-on units 56 forming a three aisled structure in the middle with two hip quarter pyramid roof room units 68 at each end, offset from the main grid. FIG. 10E is a top view showing the four core units 50 in heavy outline, surrounded by eight add-on units 56 and 68 increasing the floor area three times. The add-ons are achieved by simple wall to wall connection causing minimal disruption if built in stages. As alternative options, if the core is removed the central space could become a courtyard or a two storey high enclosed atrium. FIG. 10F is a cross section relationship diagram showing how the different units relate vertically with the two storey core in heavy outline.
FIG. 11A shows six lean-to low pitch roof room units 56 combined to form a no core building with a butterfly roof and internal gutter. Because the lowest part of the roof is internal this building could have add-ons on its two side walls and extensions on its two end walls.
FIG. 11B shows four valley low roof pitch room units 75 combined to form a square non-core building with a cross gable roof which could be easily extended on four sides.
FIG. 11C shows a top view of the combination of units from FIG. 11A and FIG. 11B in the form of a core rectangular courtyard building shown with heavy outline which can be added on to all the way around. FIG. 11D is a cross section relationship diagram of FIG. 11C showing high walls all the way around which makes for easy adding on or extending.
FIG. 11E shows the courtyard building made up of four valley units 75 at the corners with six lean-to units 56 in between.
FIG. 12 is a cross section relationship diagram showing two tiers of add-on units flanking a two and a half storey core with a curved lean-to loft 90. The first tier of add-on units 50 and 56 are two storeys high which makes them part of the four room wide core. The second tier of units are non-core add-ons 56. Making the total number of aisles six and total rooms twelve. Superimposed on this section are two storey flat units 50 or lean-to 56 and flat units 50 which have only six rooms showing that a small increase in the core height can create greater expansion possibilities.
FIG. 13A shows a gable steep pitch ‘A’ frame loft unit 66 which is fifty percent wider than unit 65 but having the same overall height and roof pitch, sitting on top of a flat room unit 50 and a flat half room unit 51 producing a one and a half storey non-core building, one and half rooms wide.
FIG. 13B shows two high pitch lean-to loft units 60 combined to form a gable roof on top of two flat room units 50 producing a non-core building two rooms wide.
FIG. 13C shows two lean-to compound loft units 61 combined to form a gambrel roof on top of two flat ceiling room units 50 producing a non-core building two rooms wide.
FIG. 13D showing two curved quadrant loft units 91 combined to form a semi circular roof on top of two flat ceiling room units 50 producing a non-core building two rooms wide.
FIG. 14A to FIG. 15E are all single width core/non-core combination three aisle structures with core in heavy outline flanked by non-core add-ons. FIG. 14A showing a single room width core having a flat room unit 50 on top of a flat height extender unit 53 flanked by lean-to units 56.
FIG. 14B showing a flat roof room unit 50 on top of a flat height extender unit 53 flanked by non-core add-on flat room units 50.
FIG. 14C shows a gable steep pitch loft unit 65 with short walls on two sides 65 on top of a flat room unit 50 flanked by lean-to low pitch roof room units 56.
FIG. 14D shows a lean-to low pitch roof room unit 56 on top of a flat height extender unit 53 flanked by lean-to low pitch room units 56.

There is thus provided a modelmaking system which permits the user to select a plurality of appropriate freestanding predesigned 3D space defining forms from a comprehensive parts library apparatus, and then to design a building by the process of assembling these forms to make an accurate model. The model can be easily modified as the design evolves and later on can be disassembled for re-use. Good design is about preventing problems rather than trying to fix them afterwards, and designing a building in this context means being able to easily explore alternative design paths as well as providing detailed information and instructions for constructing buildings which are practical to build, affordable, adaptable, economical to maintain and which utilise space and energy efficiently.
