Thank you so much for your comments, everyone - especially Tootles and OnePlan.
I love, love the idea of having a corner larder and I think it could be a great bridge between the two plans. DH wants a separate larder to store his home-made products
and to keep all our dry foods well organised at eye level. I'm more worried about distance from larder to cooker, but also like the idea of keeping all the food easily accessible in one place.
OnePlan - I love your island unit (DH hates them though for some reason he can't really explain!) and also the idea of having a separate, smaller prep sink near the cooker. You're right about the current position of the sofas - the architect showed them on the plans, but we really only envisage having one sofa at the far end of the room as that gives the best view of the garden. On the other hand, two sofas closer together probably give us more options for entertaining, and are more sociable.
Tootles - I didn't mention it in the OP, but we have already done some work in the front half of the house, and fitted the utility room and downstairs shower room last year, partly so we can use it as a base while more major work is done on the house later this year. We do have a sink in the utility room, and decided against separate access to the downstairs bathroom so that we could have as big a shower as possible. Guests do have to go through it to use the downstairs loo, but it's a very beautiful utility room
.
LondonGirl - Good point about a breakfast table, though we might be able to use an island unit for informal seating (our dc are upper primary/secondary age). We think we'll get a lot of use from our downstairs shower room as we only have one (large) family bathroom upstairs and no plans for a second one. The dc play football and are generally mucky creatures, so I do sometimes make them strip off in the utility room and shove them straight in the shower.
Will keep you updated on progress!
