I have had plans agreed for a 5.5 length by 4m width extension to my kitchen. I realise actual internal space will be about 4.9 by 3.7 when external wall width taken into account. Work won't start for a few weeks but im finding it hard to visualise fitting in what i want - a dining table, sofa and tv on thewall. I am feeling that i can't have all this.... anyone have a similar size?? I dont have the sofa or the dining table yet if that helps. I don't want a tv overpowering the room. I have option to extend length to maybe 7m but of course that will add cost. Any comments or advice welcome. Thanks.
