text: It looks like a doll’s house that’s been dropped from a great height. A bathtub dangles at a crazy angle. Bedclothes hang in the breeze. Bricks are scattered everywhere. This was Susan House’s beloved home after a huge explosion ripped off two of the walls and left the rest of the property on the brink of collapse. Susan House amazingly survived a huge gas explosion that ripped through her farmhouse - because she was out walking her dogs at the time . Fire crews were called after a tremendous blast was heard, blowing the back wall and windows out and causing substantial damage to the roof . Ms House went for a stroll shortly before the detached property exploded yesterday afternoon, leaving a scene of destruction . A bath tub can be seen teetering over the edge of what was once the upstairs bathroom after the explosion, which miraculously injured no one . The 55-year-old’s house may be in ruins but she can count herself extremely lucky to be alive – having left to take her dogs for a walk in the spring sunshine not long before the blast. She returned to find it looking like a bomb site, with rubble strewn across her garden and her belongings left exposed to the elements. The explosion originated in the kitchen, prompting the emergency services to believe that it was caused by a gas leak because the house is supplied by a propane tank. Although there was serious damage to the remaining walls and roof, some of the content of the rooms remained intact. Books were still lined up neatly on shelves in the downstairs office, a painting still hung on a remaining wall and the computer seemed unscathed. What remains of the detached home, called Bleak House, in Theddlethorpe, Lincolnshire, will have to be ‘flattened’, according to Miss House’s father. George House, 86, who has owned the property for 53 years and lives on the same street with his wife Hilda, said: ‘My daughter was out walking the dogs at the time. She lives there alone and it was really lucky that she wasn’t there. ‘She is too upset to talk about it. Due to it being bank holiday there is nothing we can do with it at the moment.’ An upstairs bedroom , still with a bed and chest of drawers in tact, is visible from the garden as the wall of the room was completely blown off . Kevin Hinson was in his garden half a mile away when he heard what he described as a 'big bang', but mistook it for a bomb going off .
