A level part of a building with a floor is commonly referred to as a story or storey. Most people utilize the story as a measuring unit of the building to determine its height. However, due to local laws and construction methods, the height of a story can greatly vary.
So the question is,一棟兩層樓的房子有多高? Here we will take a closer look at the standard height of two-story homes based on different factors as well as provide you with some useful information on how you can measure the height of your home.
Here is a quick answer.
In most US states, a standard two-story house will be18 – 20 feet in height一樓就在附近10英尺（天花板高度為8-9英尺，基礎設施或地板深度為1-2英尺。第二層的高度通常比第一層低1英尺。）9英尺. If the two-story house has an attic, the total height will be around25 – 27′.

一層樓及其結構的標準高度
標準樓層的高度大約為10英尺。這是假設天花板高度介於8 and 9 feet具有1-2 feet of infrasture thickness. But this is not set in stone as different states have their own story height laws. Stories within the same building can have different height variations.
隨著建築層數的增加，上層的高度將略低於下層，通常短1英寸。例如，與較低樓層相比，閣樓的高度將完全不同，因為該空間的設計專門滿足業主的偏好。
In Europe, two-story homes have an average height of16英尺.
在美國的許多州，標準的兩層住宅樓的高度與18-20英尺. This is considered a comfortable height in order to allow aesthetic space. Such homes have ceiling heights of 9 feet on the first floor and 10 feet ceilings on the second floor.
In homes with higher than 10 feet ceilings, the height of the building can be as tall as30英尺！
閣樓高的兩層房子
如果房子有閣樓，可居住閣樓的標準高度是7英尺。因此，帶有閣樓的兩層房屋的高度為25-27英尺.
影響建築物高度的其他因素
There are a few factors that affect the height of a two-story residential building. These are:
天花板高度
The天花板的高度on the first floor affects the height of the entire building. Builders usually allow some extra ceiling height for the first floor, with the second floor about one or two feet shorter. For example, a 2 story home with 9-foot ceilings on the first floor is likely to have an 8-foot high ceiling on the second story. We must also allow an extra foot as the floor depth, which brings the total height of a 2 story home to 19 feet.
閣樓空間
If the two-story house has an attic, this extra space will also affect the final height of the building. An average attic has a ceiling height of at least 7 feet. This is the minimum height to meet the local building code requirements. So if your two-story building has an attic, the total height of the house comes to26 feet.
Roof Type
此外，屋頂間距或風格也會影響兩層住宅樓的總高度。陡峭的屋頂會將建築高度提高幾英尺，而不太常見的平屋頂根本不會增加任何額外高度。以下屋頂樣式可以增加兩層住宅樓的總高度：
- Mansard
- Gable
- 鹽箱
- 甘布雷
- Hip
- 斯基利恩
這些屋頂類型中的任何一種都可以為這座兩層樓的總高度增加一些進尺。因此，如果你在計算兩層住宅的高度，或者你想建造一棟兩層住宅，你必須考慮屋頂的樣式，並確保你符合當地法規的要求。
如何測量兩層樓的高度
The building height of a two story building is measured from 2 feet of its foundation wall to the highest point on the structure. The height is measured as the vertical distance to the tallest point of the deck line. The standard practice when calculating the residential building height is to configure the highest point of the building, without taking into account the architectural elements, such as skylights or chimneys. The vertical distance between the completed grade and the building’s highest point assumes that the measurement doesn’t include berms. However, if the building is on sloped land, its height is measured from the average completed grade to the building’s highest point.
In order to calculate the completed grade, at least 3 points of the building are marked on elevations, one at midpoint and the other two at each end of the elevation. The vertical measurements of the highest point on the building are the average for the building height.
但是，如果兩層住宅樓有不止一個立麵呢？在本例中，需要確定結構上的最高點，並從該點到每個標高繪製一條水平線。從建築物的一端開始，在基礎牆的兩英尺內一直到屋頂的最高點。將所有尺寸相加，再除以3，得到建築的總高度。
除了煙囪和天窗之外，是否還有其他建築特征被排除在建築高度計算之外？天線、煙霧和通風點、衛星天線和旗杆不包括在建築高度內。
結論
計算一棟兩層房屋的平均高度似乎很困難，但通過考慮一些因素，例如每層的天花板高度、閣樓、屋頂間距和地板深度，你很容易就能準確估計出建築高度。雖然沒有閣樓的標準兩層房屋有19英尺高，但屋頂類型將是最終的決定因素。如果你想建造一棟兩層樓的房子，一定要查看當地建築部門的規範和手冊，以了解你所在州的建築規範要求。在開始建造兩層房屋之前，你也可以谘詢建築師或項目經理。
