Stainless steel kitchen sinks outside a property are becoming a popular upgrade for many celebrities, one expert has suggested. Director of design company Fire Magic Craig Ormiston said Premier League footballers and other famous people are taking advantage of moving their food preparation areas into the back yard, the Daily Telegraph reports. He remarked Its still quite a new idea in this country but weve had double the inquiries this year as people spend money on their homes rather than investing it.Granite sink countertops, sleek teppanyaki hotplates and ice-cold drinks fridges are just some of the amenities available to those looking to put a kitchen in the garden, according to the news source. Individuals also have the option of adding bar stools and Polynesian-style grass roofs to provide atmosphere. Earlier this year, an index compiled by interior design portal mydeco.com showed that UK homeowners are particularly house proud, with many willing to sacrifice other luxuries to invest in their property.
