A Dream!



I live not far from the city center, allowing me to drive to office in 30 mins despite the heavy city traffic. But on every average city day, I loose many things I enjoy, far most the nature. I had a dream of a house with big green garden, but in this city not an affordable option for me. Next best was to build the house near a green land, and here I am near a marshland, still not far from the city.

As any other thing, my dreams evolved. I started dreaming of a rooftop garden. After months of effort, I made that dream a true now.




It wasn’t a simple task to make the rooftop water proof. When I consult the specialists doing rooftop gardens, high-tech mechanisms and material was quite expensive to deal with.

I decided to go on my own with the low cost alternatives I would find around. Following is a cross section of my installation.


  • Bottom is the concrete slab structure. it is important to level the slab surface with appropriate tapers for water drainage.
  • Now the water proofing has to be done. I have tried with several water proof coatings without much success. Finally decides to lay a thick polythene sheet on top of the concrete surface to water proof.
  • Then it was evident that this sheet is subjected to get damaged easily. Also it was easy for the water to flow under the sheet from the edges. I decided to lay a very thin concrete layer (0.5 inch) on top of it.
  • Now the water proofing is complete. But before the soil layer, it is important to have a water drainage layer that allows any additional water to flow out. 1-2 inches of concrete gravel layer was good enough to handle that.
  • If soil is directly placed on the gravel layer it can easily block the drainage. Therefore I placed a filter net on top of the gravel layer.
  • Finally the soil layer and plants on top of everything.



It was a bit of experiments to get everything right with available alternatives. But it is quite rewarding to be close to the nature with a bird’s eye view to the marshland.



More than me, little Dinuda is the one enjoying the new space at its best!
The chief architect and team lead of the project was not actually me! it was my father who took the majority of the weight of the project.
