The Corporation of Bath wanted to expand the boundaries of the city, and Sir William's estate was conveniently situated just over the other side of the River Avon.[citation needed] Drawings of all the building plans (including many proposals that were never built) can be viewed in the Victoria Art Gallery situated on the corner of Pulteney Bridge and the Grand Parade.The planning and frontage of the entire street was done by the architect Thomas Baldwin but construction of individual buildings was done by a number of local contractors.[7] In all major dimensions there is considerable conformity, the width and height of buildings and the size and spacing of windows all adhere to a grid pattern.As the original woodwork aged or became damaged the varnish would typically be replaced with an oil based brown or dark green paint.
