Madoka's House
The Kaname residence is the home of Madoka Kaname and her immediate family in Mitakihara, including her mother Junko, father Tomohisa, and younger brother Tatsuya, in Puella Magi Madoka Magica.
The house as depicted in the anime is an ultramodern building with distinctively angular modernist design cues. Over the course of the anime, a fraction of the house's interiors are revealed, including Madoka and Junko's bedrooms, the (unusually spacious) bathroom, and the kitchen and dining room. The house's garden is tended by Tomohisa.
100 Questions included other minor aspects of the house. Question 82 reveals it is located in an unspecified part of Mitakihara's suburbs, while question 83 specifies how the house was conceived (Tomohisa's architect friend designed the house and Junko's friend, who runs a construction company, built it).
The design of the Kaname residence is much more conventional in the manga adaptation, and the house is not featured in Puella Magi Oriko Magica, as the manga does not center around Madoka.
The architectural design may have been influenced by glass houses or other modern home designs of significance, such as the Nested House N, depicted in the image below.

Within Madoka's room there are stuffed animals that look similar to Kyubey and the other Mahou Shoujo in the series. The similarities of the stuffed animals here leads to much speculation
Nested House N, a similarly designed house in real life.
