Using garage doors and all possible resources, is usually done in houses when the land is sloping, that is, in houses where the unevenness of the place is very evident and constant.

Create a facade where this garage would be on top, it would be a little harder and, thinking about the aesthetic end, it's much better to bet on the underground option.

To facilitate understanding, this type of garage may be better suited to:

  • Places with accentuated slopes;
  • Commercial establishments;
  • Houses;
  • Single storey houses.

It is recommended that you have all the planning and monitoring of a professional for the construction, as in architecture and urbanism projects, to avoid as much as possible any failure or error along the way.

Ask for the guidance of a professional in the area to perform the calculation accurately and avoid possible problems, but one thing is for sure: the longer the length of your garage, smaller will be the slope of the ramp.

And, in these specific cases, it is better to have a less inclined ramp, thus preventing the car from hitting the concrete in a way that ends up scratching or, even, breaking some piece of yours, no need.

03 – Beware of the height of the door

A special precaution that should also be taken into consideration when building an underground garage for your home is the size of the door, also known as right foot.

Ideally, the right foot of the garage should have at least 2,5 m high to prevent these accidents from happening, and you end up ruining your car early and regretting not having read these tips.

Remember that the deeper the entrance to your underground garage, more weight it will have, therefore, check the project in advance and, again, seek opinions from professionals in the field to ensure that everything will work as you need it and your safety.

04 – Put an indoor ladder

One of the main reasons for making an underground garage for your home is to increase your security and avoid getting out of your car in the middle of the street, helping criminals and bad people to end up harming you in some way.

With this, it is essential to install an internal staircase that has access to your home from the garage, since, when reaching the top, this access also has a door that can be locked in some way.

This saves you from storing the car and having to go back outside to enter the house, not making sense with the security proposal.

And, when the door is locked, it's just another security guarantee, since criminals and thieves can access your house through the garage. Of course, all information is hypothetical, but it's better to be safe than sorry.

  1. Thanks for the great post about building underground garages. How did you create the underground car park coatings? My uncle manages several skyscrapers and thinks about it too, to have an underground car park built for one of them. Good to know, that you should definitely involve a specialist here for planning and control.

  2. would have been interesting to discuss the use of car elevators to access the underground parking / storage etc. Also no mention of sky lighting. Iceberg basements in London often employ these features.

  3. Thank you for this brilliant documentation very useful. I am very satisfied. I am in Conakry ,I have my project to build a house in a humid environment with a completely basement garage I ask for advice if possible thank you
