Hi Will, I have one other question about the dev you did too. I saw in your profile photos of the finished extension. One thing i noticed is that you kept the rear bay window shaped aspect of the flat and added the glass panel or perhaps door on the right hand side. Why did you choose this over having a completely flat back with bifolds / sliding doors? I had a builder round last week and he said changing the bay window shaped bit to a flat rear is complicated due to the steel / support needed. I just wondered of your decision was planning / cost / design related? Thanks

All the above posts are excellent...................however, nobody seems to have mentioned the drain position. I'm a little concerned that some of the plans above may be unachievable because you'll never get to the drainage. Can you confirm where the main drain is. If you're really lucky, then they may cut across the property and it's conceivable that you have a drain outside the kitchen or even a manhole in the garage ( we've got one in ours, as the drain makes it's way to the front ). Like this:-

I don't like the idea of a courtyard as it feels like wasted space. I'm okay with having the room at the back. I've played with having the dining room as you walk in the front door but breaking it up with a waist high wall to create a kind of hallway and storage area. I could also move into this area by 60cm to allow for a bigger master (to take the space of the wardrobes. I think knocking yet another wall down could get pricey I guess. what are the opinions on this design attached? (doesn't inc. master bedroom.at the bottom) it should be fairly to scale.

Great ideas - all will work but I agree with Jon R - you need to live in it to get a feel for it. I did start to sketch out what you could do - but marina has done a great job of that already 😍. Have you seen the programme ’My House Made Perfect ‘ (I think that’s what it is called) some eye opening and practical designs on there. Simple solution is to move the kitchen into an L shape backing onto the front bedroom wall and creating a good space for dining or lounging area in front of the patio doors. As per my quick edit of your plan - (blue : kitchen , yellow : walls , red : storage units housing TV) Note in this if possible I would move the wall back on the bedroom just a couple feet, which would make the world of difference , lining up the storage cupboard under the stairs. You have high ceilings this gives you a sense of space - make the most of this but putting in floor to ceiling window/ patio - something like the crittal range look amazing. Your investment money is a lot but with real feature items won’t go far. But those items could be the difference between WOW and practical, it’s already practical and my gut is to spend more on the WOW 😍.
