The fabric of the nave is of Norman date, with later medieval stained glass windows. The 15th century tower has flint facings and was restored in the 19th century: it has one bell. The vestry was added in 1838. The church also has a cemetery. On 7 December 1966, the Church of St Lawrence became a Grade II* British listed building. The village is dispersed and close to both Leiston and Aldeburgh. It has a village shop, the Butchers Arms pub, a smallholding, a garage and Coldfair Green Primary School. The village expanded with the building of a small housing estate in the mid 1980s. There is also a local history group on Facebook, that is gathering information from the different families in the parish. "Knodishall Local History Group is now [2017] in its fifth year. With the help of local people we have amassed a large digital collection of photos, audio recordings and documents relating to the village." The total population of Knodishall from 1801 to 2011 has gradually increased. in 1801 the total population was just under 300 people and a slow increase until 1961 of just over 500 people. Then there is a much steeper increase between 1961 and 2001 of around 400 more people, as we do not have any census data between 1961 and 2001. Even though in 1865 when the parish of Buxlow became part of Knodishall there was no significant increase in total population to show this boundary change in the following census year. Out of the 852 people living in Knodishall, 846 of them are white and are English, Welsh, Scottish, Northern Irish, British, or other. There is one person who is mixed race of white and black Caribbean. The area and surrounding areas are all predominantly white. In the 1880s the main industries that people worked in were agriculture and dealing with commodities. These were mainly male dominated as were most industries at that time. However, domestic services had the most women and no men worked in domestic services as shown in the graph opposite. There is also a clear trend that many females did not have jobs and were most likely taking care of the household. Now in the 21st century, according to the 2011 census, the main occupations in Knodishall are retail and repair of motor vehicles and motor cycles; human health and social work; construction and education. Most of these are still male dominated, however, accommodation and catering; human health and social work; and education are female dominated.
