Prefer the second but do you need any storage?

Thanks Andrew, the first is just the existing, the second is the layout we come up with. Although not highlighted, there should be lots of eaves space we hope to utilise and also gave the walk in wardrobe for storage

The second option seems like a good use of the space. There's no measurements, but assuming it's to scale, there's not a lot of space to walk around the master bed to get to the walk in wardrobe. The ensuites are a good use of space, but you'll need to talk to the architect/builder/plumber about plumbing them in. Moving the sink in the guest suite to the opposite wall will give you more room getting in and out. And the shower is at the door? Won't that ruin the door?

Hi Nicholas, yes it’s to scale. I did think it might be a bit tight around the bed in the master. Maybe we could soften the corner of the wall by introducing a small curve? sine if our other rooms have curves so I suppose there is a bit of continuity. The layout of the en-suites definitely need more thought, I take your points about the door and sink. Thanks for the pointers

You should clarify with the architect why they have done what they have done. Perhaps they have insight into structural reasons or head height that you may have overlooked

I don’t think that’s the case, they did suggest things like moving the original staircase to open up the space.

Consider putting sliding doors to ensuites

Thanks Maya, I think pocket/sliding doors would definitely be a good option as both of those stud walls will be new.

Check the available height at purlins, anything under 5 foot is only storage in essence 
Wouldn't be overly excited regarding the second dwg as areas of space are ill thought out,
For example a huge area in front of the master bed , which is lost 
Perhaps visit another architectural practice for advise, without the roof section and relevant dimensions, a proposed plan is useless

I’m agreeing with cannonja: without seeing roof sections and dimensions it is difficult to comment, or to propose improvements to the layout.

However, the currently proposed layout for ensuite 2 appears to be unworkable.

How do the floor levels work? The plans indicate three steps up from the half landing to proposed bedroom 5, and only one step up to the master bedroom, but no steps between the master and walk in wardrobe. Are you proposing to lower the floor level there?

And ceiling heights could be an issue, at both the bedheads and in the ensuites.

The end windows look quite small and I’m wondering how much natural light they will give. Would you consider adding velux windows to the walkin wardrobe area and both ensuits? These could be fitted with electric blinds if needed

Have you considered adding pocket door to the walkin wardrobe area as well?

Hi CJ, the windows on the gable ends are the original sash windows, quite large actually (1.1M X 1.6M), so let in lots of light. We have thought about roof windows at the rear of the house ( the side with the en-suites). This layout enables us to have roof windows to bedrooms and en-suites without spoiling the look of the front side of the roof.

The en suites look like they are in a sensible place. I would agree with the comments about thinking about how the door/shower to the guest would work. The other thought is that ideally speaking I would think having the walk in wardrobe next to the en suite and not the other side of the room would be sensible. For example, if you have different work timetables to your partner and need to minimise disturbance early in the morning. This could be achieved by swapping the bedrooms and extending the current guest out to where you have the wardrobe (and putting the bed in its place) and then utting the new wardrobe where the bed currently is. Hope that makes sense?!?

HI Metty9, we did think about the en-suite next to the wardrobe, luckily we are all up at the same time generally, so it's not a big issue Your layout suggestion makes perfect sense, I just think our design gives us that extra floor space, larger wardrobe area, thus creating a larger master as opposed to two similar-sized rooms.

I think your layout works well.  The walk in wardrobe,  stairwell and two ensuites separate the two bedrooms well so sound won't cross too much.  As already mentioned the layout to the small ensuite doesn't work.  I think you need to consider small Veluxes in both ensuites for ventilation and light, which lets you use all the wall space.    Depending in where your garden is in relation to the master bedroom, I'd think about the bed placement because Velux do a great window to balcony option and that could be an amazing master bedroom feature.

In addition... I've just seen that the garden in ensuite side, that balcony is still worth thinking about though!

Hi Sue, thanks for your comments. As you mentioned we thought that the layout works well for separation for when guests stay. As another person mentioned there will be a couple of steps from the bedroom into walk in wardrobe, it should be a nice feature. We will probably have Velux windows in the em suites and the bedrooms. I love the idea of the balcony window, I’ve seen those and that would be amazing! We have some roof work to complete first, I need to get on the roof to see what our view would be like!

Hi Paul,
How about the guest en-suite toilet facing the door, wash basin next to it (all in one unit) and shower where toilet is. Not sure your dimensions but we had this layout in an en-suite that was 1.5m x 2.5m wide.

Hi Paul...
The last comment by Jonathan hits several nails on their heads...
One bedroom has more steps to get into than the other also - will the bedroom floors be at different heights? And does this effect the ceilings below each bedroom?
Is the 1st plan the actual existing layout?
Is the stairs in place?
As Jonathan suggests, more detail is required to finalise a good design/floor plan...
