"He took great interest in the passing of Acts of Parliament for regulating buildings in the metropolis, was consulted by the framers of these Acts, and used his utmost influence to prevent the endangering a whole neighbourhood by the erection of monster warehouses for private profit. He strongly contended for the principle of dividing buildings by party-walls carried through the roof, and restricting these divisions to a moderate cubic content. Writing to Lord Seymour, Commissioner of Woods and Forests, on the 28th June, 1851, he said 'that no preparations for contending with such fires will give anything like the security that judicious arrangements in the size and construction of buildings will do.' The wise provisions introduced through his instrumentality into these Acts of Parliament were continually being evaded, and clusters of warehouses quickly rose which he saw would, if on fire, defy all his means of extinction. In a letter to Sir W. Molesworth, First Commissioner of Public Works, dated 10th February, 1854, on the subject of a proposed warehouse in Tooley-street, he wrote 'The whole building, if once fairly on fire in one floor, will become such a mass of fire that there is now no power in London capable of extinguishing it, or even of restraining its ravages on every side, and on three sides it will be surrounded by property of immense value.' How literally this was realized, and at what cost, was shown by the great warehouse fire in Tooley-street, on the 22nd June, 1861, at which Mr. Braidwood lost his life."
