Economical Tips in Building Structure Design
Referring to the previous discussion, we already know Saving Money Tips on Home Improvement. Room design can be saved, but that does not mean sacrificing comfort, what steps can be taken to make the room more efficient. There are at least several ways:
Make the Room More Efficient
- The room should be a rectangular shape. This shape makes it easier to determine the type of roof construction. More simple the roof construction, then the roof construction costs can be lower.
- Rooms with a similar function are arranged close together. For example, a service room such as a kitchen, a washing place, an iron will be more efficient if placed in one area.
- Rooms that need comfort and tranquility, such as a bedroom, should not be facing west, because at that position will be exposed to sunlight for longer.
- Rooms that have high humidity, such as bathrooms, washing places, are placed in areas that have good air circulation and sunlight.
- Plan carefully the spaces that will be developed later. So there is no need to disassemble the wall or change the overall house plan. This concept is known as home development.
Based on Modules
- Try to build a room based on a 3 meter module, this will save you the use of wood and the volume of concrete. Concrete construction has limitations in length. For constructions more than 3 meters, the dimensions of the beam become larger and heavier so that the manufacturing price becomes more expensive.
- Likewise, wood construction, generally the length of wood in the market is less than 4 meters long, so if the construction length is more than 3 meters, special connection planning, and construction is needed where the costs will increase and a lot of waste wood will appear.
- The size of the room is adjusted to the size of the ceramic tiles to be used, so that not much ceramic tile material is wasted. For example, if the room is 4 meters wide, while the ceramic tiles used are 30 x 30 cm, then there are 13 rows of ceramic tiles plus 10 cm pieces of ceramic tiles, meaning that there will be 20 cm leftover pieces of ceramic tiles that are wasted.
Avoid the Juts Outward Walls
Reducing a portion of the floor plan of the house that juts outward, both in the design of the building facade and the design inside the house. The parts that jut outward will be difficult to cover by the roof, as a result, concrete roofs that are more expensive must be used.
Utilize the Remaining Space
- Wall. Aside from being a divider between rooms and building structures, walls can be used for storage. If the dimensions of your wall are wide enough, or there are parts of the wall that juts in, you can design it as a storage area.
- Ceiling. Use the remaining spaces in buildings, for example, in buildings that have high ceilings exposed, use part of the ceiling as a storage area. The use of residual space affects the efficiency of the room.

Low Cost in The Building Structure
Structural planning for buildings begins with determining the loads that will be supported by building construction, then determining the beam system that controls load distribution and lastly, calculates the structural dimensions. This plan will produce a building structure that is economical in operation but strong and in accordance with the load supported (not over-design).
Determination of the Building Construction Types
There are several types of building construction with various strengths and weaknesses. The use of certain types of construction will be related to time, availability of funds and strength. The types of construction can be divided into:
Suitable for construction that supports heavy and more rigid loads. However, in construction with a span of more than 3 meters, the cost of construction will be more expensive, because larger beams and high-quality concrete are needed.
Can be applied to long spans with dimensions that are not too large, while the construction characteristics are more flexible. For example, for a span of 6 meters only requires a beam with a height of 30 cm, compared to concrete construction that requires a beam height of 60 cm.
It is better to use it to support that is not heavy and for a not large building area. The maximum span should be adjusted to the length of wood available on the market, which is 4 meters.
Low-cost Construction Tips
To get an economical construction must be adjusted to the building area and the load supported by the building. For example, for non-story buildings with an area of at least 45 m², the use of concrete construction will be more economical compared to two other types of construction. In addition, the availability of materials near you can affect the construction costs as well.
Economical in Foundation
The most important part of the structure is the foundation. All loads on top can be in the form of tensile loads, compressive loads or twisting loads will be supported by the foundation. Based on the size of the load supported and the terrain condition where the foundation is built, the foundation can be divided into several types:
Stone Lanes Foundation
The stone foundation consists of stones arranged and put together with mortar and sand. This foundation is the most widely used because it is easy to do and the manufacturing costs are relatively cheap. For a one-story house and a two-story house can use this type of foundation, with the original soil conditions, namely the condition of the land that is not a land leveling/landfill.
(price is ± $106,22 / m³)
The shape is a square with reinforced concrete as the main material. Can be applied for flat or multi-story buildings up to three floors buildings. With careful calculations, the cost of manufacture could be cheaper, commonly used with the condition of the original soil and the rather soft soil.
(price ± $375,30 / m³).
Reinforced Concrete Lanes Foundation
The shape is similar to the footing foundation, it’s just made elongated according to the layout/plan of the building. Usually used in buildings up to 3 floors with the original soil condition to soft soil condition.
(price ± $384,30 / m³)
Mini Pile Foundation
For soft soil, for buildings with medium height level, and buildings on sloping terrain are suitable to use this type of foundation, the shape is like a pole then with special tools put in the ground, the number of poles is adjusted to the load supported.
(price of ± $92,05 / pcs)
Economical Foundation Tips
The shape is similar to the footing foundation with a size of 60 x 60 cm, made of reinforced concrete with a thickness of 20 cm, combined with a sloof measuring 15 x 25 cm. The location of the foundation is not in every column, but every 3 m span.
(price of $35,41 / unit)
With this system, the volume of excavation and reinforced concrete can be reduced. If stone material is easier and cheaper, the foundation can be made of stone with the same size. Suitable applied for one-story homes with the original soil or hard condition and not too deep.
If you encounter large spans such as in a garage or void, the use of IWF 200 x 100 iron beams, will be more economical than concrete blocks.
Economical in Beams
Beams on building structures function as load spreaders on top of it and as a rigid building structure. If it is located at the bottom near the foundation, it is called Sloof, and if at the top near the roof it is called Ring Balk, whereas if it is in the middle of the structure it is usually in a multi-story structure called beam structure (beam and joist).
A Low-cost Concrete Beams
The right concrete beam, its dimensions are in accordance with the load supported. Try the beam to be located between 2 columns with a maximum span of 3 m, if more than the span, the diameter of the steel bar and the number of steel bar to be used becomes bigger and more numerous. Consequently, the costs will be more expensive.
To determine an economical concrete beam height is 1/12 from the distance between columns. If the beam span (distance between columns) 3 m means 300 cm / 12 = 25 cm, while the width of the beam is usually 1/2 of the height of the concrete beam.
Low Cost in Column/Pole
Apart from being a rigid structure, the column also distributes the load from the beam to the foundation. Economical columns are obtained from determining dimensions precisely and adjusted to the distance between columns and the amount of load supported.
Column dimensions for residential houses are generally 10 cm x 12 cm (minimum), this 10 cm wide size is taken to fit the brick width, so that the brick can function as formwork. In addition, the surface of the plastering between the brick wall and the column will be flat.
To save the volume of concrete in a 2-story building, the large column on the top floor can be smaller than on the lower floor.
Low Cost on the Wall
The wall functions as a separator between rooms. Can be a space divider in the house, can also be a barrier between the inside and outside the house.
For exposed outdoor walls, choose the type of wall that is resistant to weather or wet and dry conditions. The wall should not function as load support, because it will cause cracks.
Red Brick Wall
Made from clay, formed then burned at high temperatures. Commonly used because it has resistance and strength to weather, but the price per m² is the most expensive compared to other walls.
Installation fee of $9,91 / m²
The Concrete Brick Ash Wall
Made from a mixture of cement and sand and then pressed with a machine. Cheaper prices, protection is needed in the form of a layer of plaster to make it more resistant to weather. Special treatment is needed, such as the addition of harmonica wire, a mixture of cement and sand which is appropriate for plastering, because small cracks often occur due to the potential for shrinkage is still large.
Installation fee of $7,79 / m²
Limestone Concrete Brick Walls
A mixture of sand and lime then press with the machine. The cheapest manufacturing costs, less good if applied to the outside walls of the house because it is easier to fall out than the two types above. To avoid this, the wall must be protected by stucco and not used to accept beam loads.
Installation fee of $6,16 / m²
- To prevent cracks in the concrete bricks wall, choose the ones that are completely dry so that shrinkage can be minimized.
- For walls that are directly exposed to the weather, use white sand for wall plaster material and use special outdoor paint. This will reduce small cracks, although at the beginning we have to pay more.
- The fence wall in the yard can use a 5 cm thick cast wall, utilizing the remaining sand sieve materials, with harmonica wire as a shrinkage reinforcement from the wall.
- For the formwork, use a 9 mm multiplex coated with oil first, so that it can be used repeatedly. If it’s finished, multiplex can be used as raw material for cabinets or Kitchen Set.
Low-Cost Wall Tips
- For walls directly exposed to the weather, you should use a red brick wall.
- While the dividing wall and inner wall, you can use Gypsum wall hollow frames or ash brick walls. Gypsum does not need to be painted. Installation fee for hollow gypsum: $13,45 – $15,58 / m².
