About the Holme Hill Conservation Area
The Holme Hill Conservation Area covers about 5.7 hectares within North East Lincolnshire Council’s area. Inside the boundary are 8 listed buildings (1 Grade II*, 7 Grade II). The most significant is Bath House at Sir Moses Montefiore Synagogue, Grade II*. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
