Hi Martin, it wasn't full wrap-around. We extended 6sqm into the side, and then just added 0.6m to the entire length at the back. We retain one of the side walls to try to save money. However, in the end we went with someone recommended by a friend and it was a disaster as he under-quoted to get the job. In the end we spent nearly £65 including £3.5K on higher-spec flooring and £16K on a higher-spec kitchen. So, doing the maths, I'd say £47K was about right for the rest of the work minus kitchen and flooring. Hope that helps!

Are Alno still trading? I thought the factory shutdown last August and the firm went into Administration?

Sorry, I know this is not what you asked about but I’m not sure why you’d need two parallel sofas and televisions right next to each other. If you laid the furniture out differently in the family space, it might impact on how you designed your windows. By having a large sofa facing away from the kitchen/dining area, it blocks off movement in the space and means that if family members are in the room while you are cooking, they are facing away from you. If you have lots of glass and reflection, you won’t be able to watch tv. You’ve got a lovely snug room right next to this for watching tv. How do you think you will use the space? You might want to keep an eye on the kids while you are cooking but I’m not sure that this layout allows this. I’d maybe think about a two seater and an armchair and a footstool to break it up and allow more movement
