I used a Vray Dome light with HDRI for the sky and ambient illumination in combination with a Vray Sun. The HDRI has clouds in front of the sun so I had so tweak the sun's setting to match the shadows' blur as well as general intensity and size.
The grass and peebles are made with multiscatter.
The grass has 3 multiscatter objects to have more freedom tweaking the secondary elements like the clovers and the brownish tall grass.
The peebles are also made with 3 layers. One on top of the other. After many configurations I found that one to be the most credible.
Interior is empty. It only has the stairs and the doors between the rooms.
The house itself has 1 master bedroom, 2 small rooms, 2 bathrooms, 1 separate kitchen, living room and dining room together (the one with the stairs). There is a garage behind the house as a separate structure and 2 car spots in open air.
