A Place to Start Most commercial buildings larger than 10,000 square feet, for example, will take 4–6 months to construct. When it comes to larger industrial buildings and more sophisticated office buildings, say 50,000 square feet or more, it can take six to eight months. The faster you want it done, the more money you'll have to spend.
That's because the longer it takes to complete a project, the higher your construction costs are going to be. Factor in inflation too-which we're already seeing today, as materials and labor prices rise-and your office tower will cost much more tomorrow than it does today. In other words, building projects tend to be on the expensive side.
The good news is that there are ways to make sure your office building project isn't too expensive. One way is to hire a licensed contractor who has experience building offices of this size and bigger. If you do go it alone, make sure you find a reputable supplier of lumber and other building materials, since making mistakes when building with concrete or steel can be very costly.
Finally, be aware of state and local building codes when planning your office tower. Some cities require office buildings to be built using certain types of materials, such as steel or wood, for example. Other cities may also have restrictions on how tall you can make your building.
Weather allowing, it is possible to complete a 3000 square foot house in 12 to 18 months. However, the period required for 3000 square foot residences with three or more floors might take up to 20 months. Also, keep in mind that the time required for construction depends on the skill of the work crew and the complexity of the project.
The first thing you should know about how long it takes to build a house is that the time required for construction depends on many factors. The size of the house, its location, the quality of the materials used, whether the work is done as a contract job or by the hour, and many other variables can affect how long it takes to build a house.
In general, small houses can be built faster than large ones. Houses in the city will be completed faster than those in the country. Detached houses will be built faster than attached houses. And houses with few windows or no glass will be finished faster than those with many panes of glass.
Size also matters when it comes to cost. Larger houses tend to be more expensive because they require more material and have more labor involved in their construction. But if you don't need a lot of space, a smaller house may be just as good an option as a larger one.
The number of units in a building influences the time it takes to finish. In 2015, a building with 20 or more units took an average of 16.2 months to finish from the time permits were obtained. Structures with 10 to 19 units required around 14 months, while buildings with 5 to 9 units took 13.2 months. Buildings with one unit or less were completed in less than 11 months.
The most common type of construction is called "stick-built," which means that no pre-made components are used instead everything is built from scratch. This type of structure takes the longest to complete because there are many different tasks that need to be done before a house can be lived in. Tasks such as framing up the walls, installing roofing material, and putting down flooring all take time.
After the basic structure has been completed, it can be finished in many different ways. A simple 1- or 2-bedroom apartment could be completely furnished or even have some of its own furniture put into it. A 3-or 4-bedroom house will usually not have any furniture placed inside it until after it's sold. These things depend on what kind of feel you want to give your customers when they visit your building.
The average cost of building a 20-story building is $1 million. Labor costs represent the largest portion of this price tag at 55%. Materials account for 35% of the total and design fees add another 5%.
