Leave the M6 at Junction 40 (Penrith). Take the first exit on the roundabout and follow the A66 towards Keswick. Go straight over the second roundabout, still following the A66 towards Keswick. After about 14 miles, you will take the slip road left off the A66 (signed Keswick). At the end of the slip road, turn left. This takes you onto Penrith Road. At the end of the road, turn left, up Chestnut Hill. Take the first right, onto Ambleside road (by a cottage called Toll Bar Cottage). After just over half a mile, you will see Chaucer House on your right (next door to Cumbria House, which is on the corner).
Parking for Chaucer House is round the back so take the next right after Chaucer House, down Church Street, and then first right down Southey Street and turn almost immediately right into the parking area (just before Chaucer Lodge). Park in the space allocated for Number 7. Once you have collected the key for the property, it will open both the front and rear doors of Chaucer House, which may make unloading from the parking space easier.
