The land at KB2 (Gypsy Lane) is designated green belt land. No exceptional circumstance exists which would lead to the conclusion this land needs to be developed.

The land is bound at its western side by the A1(M) and subject to atmospheric and noise pollution from the motorway; it is not suitable for permanent housing and is particularly unsuitable as a site for a
primary school.

The land is prone to flooding (and in particular runoff from the A1(M) when the drainage pond fills); existing housing at nearby Broome Grove suffer from this runoff.

No provision has been made for any future widening of the A1(M) which is two-lane through its Knebworth section.

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