Dear Lydia, I think would be best to place the sofa facing the window or if you plan to get more than one, I would put one in the middle two on the sides. I have seen a similar kitchen to your earlier, and the sofa was facing the feature wall with the large windows. It looked stylish, well organised and overall it was a great atmosphere in the open plan kitchen. Turning the sofa towards the kitchen side-I rather see it as making out a kitchen of the entire space. Be creative when picking furniture, after you still have the ability to move them around. Add dimension to this space and of course some decoration is also needed. StJames Design Interiors

My window seat is a bit unconventional but it's such a bright spot in my home and my daughter and I LOVE it!!! It's our photo Opp corner as well...;)

Fantastic idea for seating, been beautifully designed.

I have built in seating around radiators in both my sitting room and hallway and we have triple glazing and external insulation. The seats are designed to be able to lift the covers to let heat out if needed. It’s comfy to sit in and we have not had issues with heat build up. The rads are not as efficient this way for sure but we have had no issues with the areas being cold as a result.
