New Ideal Homesteads were the biggest and most successful developers working in North West Kent in the 1930s. They cut construction costs by using prefabricated materials and promoted their products and the finance that enabled their purchase vigorously. 

New Ideal Homesteads' success was partly based on providing potential purchasers with access to a mortgage as well as their dream house. They priced their houses at the bottom of the market and made the deposit as low as possible.

It is significant that they were prepared to accept a deposit as low as 5%, that they often priced houses at just below the nearest £100 and failed to draw attention to the repayment period of the interest rate.

The Montrose Park Estate was built in the 1930s and is centred on Hurst Road, Sidcup. The Estate's name has no local link.
