Situated in the Royal Borough of Greenwich in London, Eltham has a rich architectural history that spans centuries.

One of the most famous landmarks in Eltham is Eltham Palace and Gardens. The palace dates back to the medieval period and was a favorite royal residence during the Tudor era. The Great Hall, built in the 1470s, is a fine example of medieval architecture. The palace was later renovated and expanded in the 1930s, incorporating Art Deco and modernist design elements by architects Seely and Paget.

Eltham has several surviving examples of medieval and Tudor architecture, including St. John the Baptist Church, which dates back to the 13th century.

Like many parts of London, Eltham experienced suburban expansion in the early to mid-20th century. This period saw the construction of residential neighborhoods with semi-detached and terraced houses to accommodate a growing population.

In recent decades, Eltham has seen modern developments, including the construction of new residential buildings as well as some older buildings being repurposed for new uses. The town has evolved over time while retaining its historic charm and character.
