As you arrive into Brighton station and walk through the barriers, turn left and walk back along towards the car park. Head towards the Jurys Inn, just before turn right down the steps, then crossover the road and walk past the climbing wall and round to the right. Through the gap you'll see New England House, just crossover and walk up the stairs to Level 5.
From the A270 New England Road, turn left into New England Street, New England House is on the left hand side. If parking, as you turn into New England Street take the first left and follow this road, there is an NCP car park on the right.
