Should come within PD if you aren't enlarging. You could need change of use to habitable space. You will def need to conform to building regs and this conversion is notifiable. Contact a local architect and or your local planning office/ building control if you need more help.

Thank you Thomas that's great - very efficient!! As the space has hard floors and walls it looks like your lacking in the soft furnishings side which is giving it the cold - office like - appearance which is sometimes a little uninviting. A rug will help soften the ground placed under a central coffee table. I would then consider adding some layers or textures and colour with a few cushions and some art on the wall above the sofa. Above the desk I would add a few short shelves which I would include a plant which soften interiors instantly and add life. This will also give you some great additional storage. I can also see two small ledges on either side of the room - this is perfect for some statement lighting with a strip of LED lights down either side. This will add wow factor and a contemporary statement. I hope this helps. Thank you, Gina
