seeking ideas for floorplan

Now we're beginning the repairs on the old house, we need to get the floorplan sorted. I have some ideas but would love to get your opinions and suggestions.

It's a bit complicated because we're designing it with two purposes in mind. It will start out as a self-contained cottage which - although small - will be comfortable for Dave & I, or anyone else to live in. Ultimately though, it will serve as an annex suitable for providing upmarket B&B accommodation.

We don't want to impinge on the design of the "dream house" which will be built on the other side of the cloister. We also want to minimise the cost, which means sticking to the current footprint of the house rather than extending it outwards or upwards. Here's the layout at the moment:

It is basically 3 rooms and a hallway. There used to be a lean-to extension at the back which housed the kitchen and bathroom but they weren't covered by the "new" roof and are beyond saving.

Dave and I played around with a few designs tonight. Here's what we've come up with so far. We're going to run them past Eric (our architect) too, just to make sure we haven't made any monstrous mistakes - but he's focusing on the "dream house" so I don't want to distract him! Any ideas and comments are welcome, please just add them below.

First, this would be the plan for it in the cottage mode (click and then select "original size" to get a bigger view). I've drawn in furniture to scale to give a rough idea of space:


Basically, it would have 1 bedroom with ensuite, study / guest bedroom alongside the laundry (reason for this will be clearer in next plan), cosy lounge, leading to dining area and small but functional galley style kitchen.

Second, this would be the conversion to make it suitable for upmarket B&B:

There's no change to the structural walls. The only changes are, the laundry converts to be the ensuite to what is now the second bedroom (formerly the study); the "linen cupboard" converts to a wardrobe; and the giant walk in wardrobe in the first bedroom converts to house built-in bunk beds, so that if we had anyone with kids staying there'd be somewhere for them to sleep. I've seen this "bed in a cupboard" trick done at a Californian B&B in Sonoma and it worked brilliantly. When you're using the bed you have the sliding door open; at other times you keep it shut and no-one's the wiser.

What do you think?
