How would you design/section up this extension?

[Curiosity101]

DH and I are considering upsizing, but equally, we're considering an extension. If we did extend then our current second bedroom becomes huge so what would you do with it? The first image shows the layout as it would be after the extension, top left room is the room I'm looking for ideas for. The second image is one of the ideas I came up with for it.

where is your existing bathroom?
Do you want a dressing room or are you planning wardrobes 7n bedroom?

I think the master bed and ensuite work well on your second image, but rather than create a tiny 6th bedroom out of the left-over space, I'd knock through to the bedroom in the bottom left corner. So you'd end up with 4 good sized bedrooms and 1 small one, rather than 3 good sized bedrooms and 3 small bedrooms.

Oh - good point from Bruce about the location of the bathroom...!

Sorry, I've updated the pictures to make it clearer.

I'd like a dressing room but it's not vital. My plan was to put wardrobes along one of the walls. I've just moved the door from the ensuite on mine design to be in the same area as the door into the bedroom. That way we could have built-in wardrobes along the ensuite wall, or the bottom left wall.

@PowerslidePanda I hadn't considered making bedroom 4 bigger. I'll add that to the list thanks .

@PowerslidePanda Here's your suggestion. I think it makes for a really nice sized bedroom but I'm not keen on sharing a wall with one of the DC if possible. Having said that I think I'd put wardrobes along the shared wall which might help muffle noise.

Make the excess space into a utility room. You should have your washer and dryer where your bedrooms are rather than lugging clothes and bedding up and down stairs.

I'd make bedroom 4 the ensuite and make the 4th bedroom where the ensuite is. Your water supply is clearly the other side of the house so getting it to the ensuite would be expensive

@Midlifephoenix Thanks for the suggestion, this first floor extension will be over a ground floor extension that will give us a utility room so I think we should be ok in that respect.

@Baxdream We've got the main supply running under the extended room so the water supply is fine in my original idea. But it would need a new sewage/waste connection which isn't ideal. Moving it to where you've suggested would mean we could use an existing drain as it's directly above the outside sewage drain. Just a shame it makes that office/5th bedroom so teeny tiny.

Ah that's great! Do you need the office? You could put a door near the stairs and you could then have the office as a dressing room and it would be a lovely master suite.
We did an extension on our last house and had a huge bedroom with dressing room and ensuite and it was amazing!

@Baxdream We definitely don't need the office. I was thinking more about future flexibility and eventual resale value. I figured I could always use it as as a dressing room anyway in this layout. It just wouldn't have direct access from the master bedroom.

Plus if we do go ahead with the extension it'll be a multi stage project (subject to planning of course) . Ideally it would also include a loft conversion. We'd go from a 4 bed 1 bath house to a 7 bed 3 bath house, plus adding a utility room, porch and a wider garage. Although I would probably expect to market as a 5/6 bed as you'd probably expect more 'living' space than we'd have available if you marketed as a 7 bed.

Why not steal a bit from main bedroom to increase size of new weeny bedroom (green line) , make the resultant alcove a cupboard or an office /desk nook (red dotted line), make ensuite longer on other axis to stop it feeling cramped by door (blue line)

@BruceAndNosh Definitely a good idea to consider, thanks for that. 👍
