We make and supply our own pig arks. They are 8’x6′ with curved steel box section roofs in polyester grey. They come without floors but we can supply one at an extra cost. Farrowing doors can also be accomodated. They have pre cut hand holes for you to lift the arks and move them. The standard ark is £160 see http://www.new-close-farm.co.uk for more details. Delivery is available.
