M: I’d like to share with you today my experience with a new approach to building a house. It’s called Envelop Building.
W: Hmm, it sounds interesting. Please share with us. What does it mean?
M: Essentially, what it means is that as you are building a house, you try to leave the landscape feature on the land, especially the vegetation in the original condition. So what you are not doing is the usual practice of "land scraping". By which I mean literally scraping or cleaning the land of any and all the original plants.
W: Why is the approach called Envelop Building?
M: Good question! Because instead of clearing everything away, you let your original landscape elements envelop or surround your house. Let the vegetation physical features such as hills and slopes or interesting rock formations, constitute a significant part of the character of the building site. The design of the house should take these features of the land into account.
W: Any more information about Envelop Building? Is it a recent technology?
M: Actually, integrating your original wild landscape with a house is not that new. The famous American architect Wright was doing it about 65 years ago. Envelop Building is not as easy as it sounds though. It’s not just that you build your house and leave the land alone. By building, you are already damaging the original landscape. But as architects, we should try to work with environment, not against it. A creative architect can find ways to incorporate natural landscape into the overall design.
W: I guess this technology will be acknowledged by more architects.
