Continuing the topic of construction, it is important to emphasize that the much faster construction process of granny annexes for sale has a direct impact on the construction cost. The lower complexity of the work does not require the use of expensive equipment. Building materials can also be delivered by easier transport even to hard-to-reach places. Granny annexes also have greater advantages when it comes to reconstruction (for example, if an additional wall is needed). In the case of a brick house, the implementation of such changes will require additional concreting of the wall, which is more reminiscent of another construction process than a simple reconstruction.
It is not difficult to understand that granny annexes also differ in price from brick or blockhouses due to building materials. Given that fact, the construction of such a building is in all cases much lighter than the construction of a brick house. This also affects the wider choice of foundations for the house. For the construction of the wooden house, it is possible to use simpler and cheaper – pile foundations, which are usually drilled or plug-in types. In the case of brick or blockhouses, much stronger foundations will be required, such as planar ones. It will cost more to install than a pile foundation – with a plinth finish and good insulation, it will range from an average of € 60 to € 70 per m2.
Another factor that has a significant impact on the construction costs of brick and wooden housing – is insulation works. It is worth noting that when comparing brick and wooden houses, which are not insulated, a wooden building made of brick far exceeds its natural heat wall resistance. This means that if you want to get the same thermal savings that a non-insulated wooden house has, you will have to spend a lot of money to insulate a brick house.
For those who want to understand how much granny annexes cost, it is worth knowing that there are plenty of offers available on the market for every budget. However, you can buy a simple cottage with an area of about 30 m2, which does not have modern solutions, for about 6,000 euros, not counting the additional insulation and interior installation work.
