The crescent, which is a grade I listed building, comprises 20 houses, each originally having four floors together with servants' quarters in the basement. It is arranged as a concave crescent, and is flanked by Lansdown Place West and Lansdown Place East, both convex cresecents and grade II listed buildings in their own right. There is also an archway connecting 20, Lansdown Crescent and 1, Lansdown Place West, which is a Grade I listed structure, and which is thought to date from the time that William Beckford owned both properties. The buildings have a clear view over central Bath, being sited on Lansdown Hill near to, but higher than, other well-known Georgian buildings including the Royal Crescent, St James's Square, Bath and The Circus, Bath.
The grass in front of the crescent is sometimes used to graze sheep.
