Using natural light to illuminate a wellness area in a modern residence’s basement zone: here’s the BIM approach for modelling a dug in terraced area
The Park House project is a residence located in Madrid and designed by the architectural design firm A-cero. It manages to perfectly encapsulate fusion and symbiosis between the villa and the park that surrounds it.
The care and attention that the designers paid to the many details is mainly due to the great ability to make adjustments and changes to the project in order to meet the specific requirements related to the dynamic lifestyle of the family members: the pleasure of receiving visitors, the need to work from home, sport activities, the need to keep in contact with nature and the surrounding landscape.
Strolling around Park-House, a staircase makes its way through the ground and the walls of the house. The designers intent was to connect the interior of the dwelling with the exterior park. Revealing the extensive underground spaces that take in the natural light through the large surrounding windows.
Let’s now see how this particular building characteristic is modelling using Edificius: the BIM approach for modelling a dug in terraced area.
How to reproduce earthworks using a BIM software
After having defined an excavation area, we can then proceed to tracing the large steps that lead down to the basement using the “parallel guideline” 2D drawing entities. Again, for each step we can simulate the “cut and fill” volumes by assigning an adequate depth for each one. This data can be entered manually in the properties toolbox or by simply adjusting the elevation in 3D view with the help of surrounding height references used as snap points.
Creating a light well opening with a BIM software
The purpose of “terracing” a given area is to provide natural lighting and an external view to underground environments. This next phase is quite simple, in fact, we’ll simply modify the outside facing wall and lower its height entering a new height value in the properties toolbox, or even manually in 3D view. This newly created opening allows us to set-up a curtain wall object and insert it directly on top of our previously lowered wall.
How to build the large steps for our terraced light well using a BIM software
To make things easier we’ll now hide certain entities so that we can concemtrate more on this specific process. So let’s hide the entities above ground level. We’ll restore them afterwards to see the overall result.
At this stage we’ll define the riser characteristics of our large steps. These obviously have another function which is to act as a containment stucture for our landscape works.
So these all have the same size and we can simply copy-paste them directly. Consequently forming the tread leads the process to assigning a material (texture) by choosing among those available in the online BIM Objects Library (online Catalogue). In this case, we’ll go for the grass effect.
Inserting vegetation elements with a BIM software
In conclusion to complete the terracing works and harmonize it all with the surrounding environment, we’ll add some vegetation elements. Selecting the vegetation tool we can choose from a wide range of plants and define their density, size and distribution. So this will give the feeling that the park follows through with the large steps to the Park-House residence fitness area entrance.
This phase completes the project now ready for a presentation.
