KB4 is on a slight rise east of Knebworth, which currently offers views over open countryside. In particular the recreation ground has an open view to its east over the site. Access to the main north-south road from the east is very restricted, via narrow (in some parts single-track) Swangleys Lane; Watton Road - a residential street with speed bumps; or St Martin's road (a private road.)

The proposed development here would narrow the green-belt barrier separating Knebworth from Stevenage (at Bragbury
End.)

Access is difficult due to local narrow lanes and low bridges.
