徐家大院是特色田园乡村中一组产业办公综合服务建筑。位置在乡村边缘，是密集的乡村与空旷田园之间的过渡。布局延续村庄肌理特征，顺应道路与周围房屋布置。四栋不同功能的建筑围合为一个半开放的院落。

外墙材料南面采用水泥砖直接刷白，保留砖缝，不做抹灰，其余东北西三面采用乡村里常见的造价最便宜的水泥砖，不做粉刷。

The south exterior wall uses cement bricks, directly painted white, retaining the brick joints without plastering. The other three sides of the exterior wall adopt the cheapest cement bricks commonly used in the village without painting.
