Natural light study
We help you designing the best enlightened property
Our technical team supports you to optimize your properties' natural light while taking into account your constraints
After analysis of the plans of the operation, we offer various options to improve the natural light and sunshine of your properties. We suggest modification about the size and location of the openings, the arrangement of the rooms or the color of the coatings used.

With our help, you can increase the natural light of your properties by 9%.

Solen support during the design

On average, our customers increase natural light of their properties by 9% and their final prices by 0,5%

Proposal for plans' alterations
Proposal for plans' alterations
We will suggest modifications of your plans considering your technical and regulatory constraints, without increasing your budget. With the proposed changes, we improve the natural light of the properties from 9 to 10%. By linking the price of your properties with their natural light, we can increase your turnover from +0.2 to 0.5%.
Suggestions for changes:
  • Size of the openings
  • Position of the openings
  • Room layout
  • Position of the balconies
  • ...
Example 1
Suggested variant:
Invert the windows of the bedroom and living room (width of 180cm in the living room and width of 90 cm in the living room)
The living room gains 1:30 of natural light on average over the year and the price of the apartment increases by 0.6%
Example 2
1st suggested variant:
Remove the winter garden
Gain of 5:00 average natural light per day in the living room
2nd suggested variant:
Put simple glazing on the winter garden and leave the double glazing on the heated spaces
Increase of 8% of the natural light of the living room
3rd suggested variant:
Put a clear coating on the ground of the winter garden
Increase of 15% of the natural light of the living room
4th suggested variant:
Enlarge the windows overlooking the winter garden
Increase of 19% of the natural light of the living room
