Perry Bridge, built in 1711 in Perry Barr to replace an earlier bridge, is another example of a structure built during this time. The industrial expansion of Birmingham attracted industrialists to the city and Soho House, in Handsworth, completed in 1796 to a design by brothers Samuel Wyatt and James Wyatt as the home for the wealthy industrialist Matthew Boulton, is a well-preserved example of what the industrialists constructed for themselves. The Industrial Revolution did not just attract wealthy industrialists to Birmingham. The need to house the many industrial workers who flocked to the city from elsewhere in the United Kingdom during the Industrial Revolution led to the construction of many streets and terraces of back-to-back houses, some of which were later to become inner-city slums. Remaining examples of inner-city domestic buildings are located on Kingston Row, which was built around 1780 and modernised by J. A. Maudsley, the City Architect of Birmingham, in 1969. A later example of back-to-back houses are the Birmingham Back to Backs, the last remaining back-to-back houses in the city, which were built in 1830 and recently renovated and turned into a museum run by the National Trust. Many residential properties dating from around this period are listed buildings.
