The six-bedroom contemporary designed houses at Carlile Place are set in a peaceful location in the heart of Richmond Hill.<br> <br> Harepath, a niche property developer in South West London, specified Total Home Environment's central vacuum systems because it was committed to high quality design and passionate about environmental issues, Total Home Environment says.<br> <br> Traditional vacuum cleaners re-circulate dust and harmful allergens, such as dust mites, from their exhausts. Total Home Environment's Central Vacuum removes all of the dust and allergens to a remote collection point, improving the quality of the air in the home and making it a healthier place to live, the company says.<br> <br> Peter Whiteway of Harepath, commented: "We required a vacuum system that would enhance the specification of an expensive house in one of London's best areas. Total Home Environment's Electrolux Central Vacuum system is efficient, makes vacuuming easier and requires little maintenance."
