Cost of building a house

In assessing the cost of building a new home , many people use the square meter as a basis for comparison.

Let’s see what we mean when we talk about square meters (sq m or m²).

That of square meters, is a method to compare the approximate cost of construction of two or more similar homes in different parts of the country and even houses with different characteristics. But the method of square meters is not reliable to determine how much it will cost you a property based on a particular design.

Based on a project with some specific questions, you can get a rough idea of costs. This is a start, but for a custom home of 100 square meters, for which we had a budget of $ 3,500.00 / sqm, and a final cost of $ 350,000.00 is not difficult to get to spend $ 400 or even 450 thousand and This may depend on several factors.

With a bit of research, the method of square feet can be a useful tool to get an idea of the price of a football field, nothing più.Dopo doing a search on the likely construction costs in your area, remember to add the cost of land, which is not negligible.

DESIGN, SIZE AND MATERIALS Many parameters affect the cost of building a house, but there are three main dimensions , complexity and level of finish . The effect of size on the cost of construction is evident, bigger houses cost more. But it is not as simple as it may appear.

Significantly more important than the size of the place, the site where you are going to build.

The ” cost per square foot “of a house varies greatly even from one room to another. The rooms like the bathroom and kitchen, which are full of plants “hydro-thermo-sanitary” will cost more rooms “empty.” Even the type of finish greatly affect the final cost: floors made with simple single-fired tiles will cost much less than those in marble or other more expensive materials.

COMPLEXITY OF THE PROJECT   A simple form, maintains low construction costs.

The effect of the complexity of a house on construction cost is often misunderstood, and it’s one of the sources of unpleasant surprises for many buyers.

Simply put, a house is complicated more expensive to build a simple house. What makes complicated the construction of a house? Mainly is the shape of the house, the ratio of the amount of the roof and the amount of foundation with the rest of the construction.

Consider two typical models of construction: the first is a colonial house in rectangular shape with two floors and the second a typical French farmhouse, with a master bedroom suite on the first floor. Both houses are 1,000 square meters, and both have the same level of finish.

The colonial house is the image of simplicity, both plans have exactly the same dimensions and are stacked one above the other directly. So, while the house is 1,000 square feet, the foundation and the roof are only 500 square feet (I’m ignoring the garage for this example). It ‘efficient and easy to build.


The French construction is the same size, but is less efficient, with the master bedroom suite moved from the upper to the lower surface area of the roof and the foundation increase of about 500 square feet – but the overall size of the house remains the same: 1,000 square meters. A greater surface area of the roof and foundations contain the same area, more and more concrete timber equals higher costs.

The colonial houses have simple roof “hut” with two slopes sloping. In the simplest examples the roof is made entirely with a single truss. This is a huge advantage for manufacturers – each truss is the same! And with no roofs or dormers that intersect, there is no need to install metal beam, everything is made of wood.

The design of the house French is distinguished by its more “irregular”. The French pavilion roofs are typically four layers rather than a hut and are often more sloping, so you need more wood, and the roofing job is more expensive.

Intersection of slopes, windows, dormers, porches, corners etc. … increase the level of complexity in the building of a house. If you are considering a number of projects, seeking aesthetic complexity can significantly drive up the final cost.
