In March 2015 an additional 12 archaeological test pits were excavated in North Warnborough by 48 Year 9 students from Connaught School, The Costello School, Cranbourne Business and Enterprise College, Robert May's School and Fort Hill Community School. The 2015 excavations added to the 11 test pits excavated in 2013 and the 10 excavated in 2014, to bring the total so far dug in North Warnborough to 33. The majority of the test pits were sited between Dunley's Hill and the canal as well as a number that were excavated in the far north of the village.
The first datable pottery excavated from the 2015 test pits was identified as being high medieval in date, from about the 12th century onwards. The results have infilled the gaps in the medieval settlement activity from previous years to show that the village was likely one linear settlement with additional activity to the east towards Odiham. The lack of later medieval finds again supports the notion that the village had contracted greatly during the 14th century, only one test pit from 2015 yeilded any pottery of this date (NWA/15/9). During the post medieval the village expanded once more with additional settlement activity also identified to the north of the river for the first time since the 2013 excavations, and continued to grow into the village that can be seen today.
