A Lego-mad couple have spent four weeks working 14 hours a day to create this stunning 21-foot-long replica of Old London Bridge in their own sitting room.<br /><br />Every year Mike Addis, 63, and Catherine Weightman, 58, build a massive Lego creation in time for Christmas.<br /><br />And their 27th project has just been completed using 400,000 Lego bricks.<br /><br />They have recreated Old London Bridge of 1400, one of several bridges which spanned the Thames at Southwark, including 78 houses, 500 mini-figures, a castle and chapel.<br /><br />Features also include guards patrolling the pay toll of the bridge and bakers and residents.<br /><br />Their London Bridge model measures 21 foot long and is three foot high. <br /><br />However it only includes three quarters of the bridge's entire span, as the full size wouldn't fit in the house. <br /><br />The model was inspired by the medieval Frost Fayres which were held when the Thames froze over from the 16th century.<br /><br />The couple took four weeks to make the model after starting mid-November and finished in mid-December, sometimes working 14 hour days to complete it in time. <br /><br />Economics teacher Mike said: "It's probably our most impractical model because it's right through the centre of the room. <br /><br />"It splits the room in two - there's a foot gap at one end to get around to the other side of the living room. <br /><br />"We had a party recently with people on one side of the bridge and some on the other.<br /><br />"Most people are in awe because it's so big."<br /><br />Mike is now planning to fit himself, Catherine and 12 family members - including young children - around the carefully constructed model for Christmas. <br /><br />He added: "We have the settees on one side but the heaters are on the other side.<br /><br />"We have separate Lego for the children to play with."<br /><br />The couple even visited an existing wooden model of the bridge in St Magnus The Martyr Church, London as part of their research to build the Lego replica. <br /><br />The couple previously built a huge polar bear and model of Ely Cathedral, they recycle the bricks each time - carefully placing them into colour and size categories when deconstructing.<br /><br />Mike said: "Everything is individually made, each house is very different. <br /><br />"Some days we were working 14 hours to get it done. <br /><br />"You have to be patient. Some of it is quite tricky. To make the curved arches we had to build them with half bricks." <br /><br />The model will stay up until January 6, when it is traditionally taken down. <br /><br />The couples love for Lego was spurred from childhood but reinvigorated when a family friend visited with their child and they fetched their Lego from the attic for him to play with. <br /><br />Mike added: "We realised how much we loved Lego. We do it with friends sometimes - a pal came over one weekend to help us."
