Sunnyside is a detached house in South Marston, Swindon, Swindon (SN3 4RT). It has a recorded floor area of 48 m² (around 513 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (March 2009) shows an F (score 22), near the bottom of the EPC scale. Main heating runs on electricity.
