There will be better comments from others on the plan but from me you definitely need a toilet with basin separate to a bathroom. Peak times for the bathroom with multiple combinations of family needs a separate toilet.

we need to see the whole floor plan upstairs and down, are there any special views, where is north and please describe the local climate but i'm wondering if 4 adult kids and their partners use 4 bedrooms and the kids have the downstairs bunkroom...where do you sleep??

Thanks oklouise. These four bedrooms are over the garage, it’s the only space for them to go, I would love some design input in how to tweak the bathrooms etc. Bedrooms 2 and 3 look out onto gardens, facing West.
Our bedroom is in the main house, as is living and kitchen, dining and outdoor deck area facing East.
Downstairs is an open space, that will eventually have bunks or single beds in it.
There is a laundry and bathroom downstairs for the family to use...so that’s why we think we can eliminate the upstairs one and better utalizing that space.
We are in Mornington Peninsula...so Melbourne weather.

Bedroonm 3 and 4 that is.

what is the small space next to the laundry and where is the stairs?

The small space is the lift foyer and the stairs are next to that

my suggestion has four equal sized bedrooms with a larger shared bathroom, one ens with variations of biw in each bedroom plus an extra luggage storage room...the compartmented bathroom can be used by a crowd at the same time with plenty of storage for linen under the handbasins, mirror doored wall cabinets for toiletries and including a bathtub and extra large shower will make it more comfortable with younger children...there's space for a queen sized bed, wardrobes and an end of bed ottoman for sitting, placing luggage and storage for extra bed linen and pillows ..you may notice i haven't included big windows on the western garden side of the house to exclude hot afternoon sun although tall narrow (or wide) windows with external screening would improve ventilation

Thanks so much Oklouise....Amazing what a fresh set of eyes can see. I love that all the rooms are the same size, and we still have 2 bathrooms. I am locked into those large front windows ( and all windows) in beds 3 and 4, so beds would have to go on other walls..but that will still work.

furniture can move and/or beds can be against window walls

As its a holiday house, Im thinking wardrobes don't need to be full width behind doors, Im trying to find some inspiration via hotel rooms for clothes storage, some hanging, some shelves...maybe behind doors and then a bench, so that if you want to live out of your suitcase or bag that's convienent also. Does anyone have any good inspirational images of this concept please.

Thank you oklouise..another clever option, and furniture moved around fits well. I do like the option of the ensuite....that would be the prized room...is there room to make that also accessible from hall ?

i deliberately made small wardrobes half hanging and half shelves as i think it will be good to have a bench/desk for a set down space for laptop, phones, charging station, emptying pockets etc and bedsides could be drawers for undies and PJs... we only use a bench for open lugagge, chair, bedside drawers and a hanging rack on the back of doors for our holiday cottage and don't need more ..you asked if the ens could be accessed from the hall? not if you want to keep the shower, storage room and/or direct access from the bedroom...it sounds like the challenge is attempting to make all the bedrooms and bathrooms equal for all the adult children but for the rare times they all visit together maybe it would be good to have one bedroom a little bit special for first come first served or maybe for a new baby?? will think about other options for the second bathroom but this is another option i discarded in favour of the bigger bathroom

Wow...Thankyou Oklouise....and the great ideas keep on coming. Yes the Mum in me is trying to keep it all equal....the storage solutions are sensible and the bathroom options are great. ...it’s great all rooms the same size..all a big improvement on what we started with. Ps the lift shown in the last 2 plans can be used as storage etc..as the lift is located further down.

We are thinking we like v2. Love the bigger bathroom ..we are happy to loose the storeroom next to smaller bathroom if it could help with the flow of that space...maybe leave the shower where it was but move it across to lower ceiling space to make room for door from corridor. We can utilise the space labelled Lift for storage Thankyou.

Thanks oklouise..sorry my wrong terminology has confused you. Ceilings are all standard height. By low ceiling I was referring to the smaller bathroom and I should have said...the angle of the wall..the corner of the room is triangular 😩

You were asking about ensuites and not the rest of the house but I can't help making comment on the amount of angled walls which make for difficult furniture layout and wasted space. The 2 walls that I find hard to accept are the ones ringed in Blue and opening to the pool, they both have a slightly different angle to each other.

The fireplace is awkward and adds extra angles in the living space and corner in the Master, Could it be straightened and changed to either of the two suggested blue boxes

The Kitchen Pantry, again angled walls which would work better squared off and better still flat against the wall so that you could keep an eye to the pool

The pool showed a very pointed angle in the whole floor plan which wouldn't be practical for use and cleaning, In a different shot you show the pool being different?

My suggestion for the bedroom wing is to remove the long angled wall which is difficult to fit out and furnish.

The bedrooms are a very rough draft, the bath space would be split and possibly add a shower room next to the stairs for those using the pool plus extra for the 4 bedrooms, you already have a powder room on the other side of the stairs.

Just my thoughts when looking at your plan thinking it could be so much simpler and flow better

And just another thought, why are the Bunk rooms down stairs, is it due to space, I would have thought it would be better for them to be upstairs with all the adults downstairs with you and your master suite?

All bedrooms except the bunk room are on the same level, you either use the lift or the stairs to go down stairs which would be to the rear ground level and bunk room/s

Wow. Thanks so much siriuskey...yet another set of eyes and more great ideas and observations. I really appreciate your efforts.
The block is irregular, splaying out at the front, consequently some of the funny angels. We have a very strict building envelope and can’t move outside this. We are in a flood zone..so no habitable rooms are technically allowed downstairs.
I agree you’re ringed blue walls could be straightened.
The fire place angle is designed so as not to impact on the view..see my diagram showing view lines. I have questioned the waste of space and awkward angle it creates also. On the other side of the fireplace wall is a coffee/bar station..a well used spot in a holiday house.
I’ve thought curved walls could achieve the same idea, but with a softer look. I’m thinking a large curved, semi circle couch around fireplace tv area would work and allow for traffic flow in the area.

I have had the kitchen independently designed incorporating the shape, somewhat squared off internally to give a good functional butlers pantry...I do like the idea of being able to look beyond it to see the pool.
The other side of the butlers pantry is a study area.

The correct version of the pool is the one attached now. It gives more seating space inside pool area.

...scanned plans to follow.

I was reducing the foot print by removing the angled wall which will give you a beautiful sun filled entrance courtyard .

Why have an angled wall for the pantry that you square off internally? KISS, keep it simple

The fire place could be flat against the wall with a coffee station next to it, or across next to the kitchen

Can you explain where the Bunk room will be added as I can't see it. thanks

We currently have a restriction on habitual rooms downstairs...we hope to be able to modify this requirement once the build is underway and then create some bunkroom space downstairs.

I also quite like the 3 bedrooms in . a row upstairs, however the placement of the shower opposite the pool is in the space allocated for the lift, so i think we would need the extra bathroom space near the bedrooms too.

Going by an earlier comment I thought the lift was being moved forward

"We can utilise the space labelled Lift for storage Thankyou."

Sorry for the confusion..it was wrongly labelled. Lift is next to that space.

Oklouise and Siriuskey and others thanks so much for input. I’ve attached the version we think works best, but would like to configure the other space as a semi ensuite with hall access also, maybe we need to include the corner storage space as I have shown to make it work. Siriuskey, I have taken your advice and removed internal angle walls for fireplace,tv and butlers pantry and have realigned the other small wall as mentioned. We will reconsider when we are at built stage, how to define the spaces...I am liking the idea of cured walls to soften the other angles. Just wondering if I could stretch the friendship and have one of you re draw the small bath room into that space as shown I would be very grateful.

I should have posted these sooner, but here goes, as it is a beach house showering will be enjoyed with out door showers, my family and guests love them.. I feel like renaming your house Angle House not to be confused with Anglesea

you asked to redraw the small bathroom to include the extra space but do you want a door from the bedroom as well as the hallway?

I'am not a fan of a long angled wall unless it butts up to a straight wall IE: as per the Bathtub wall. But if you are considering to keep it then this space would make a great linen room. This floorplan and the one above will give you two separate toilets (important for 8 adults) and free up the bathrooms

Thanks so much siriuskey...again more clever options. Unfortunately we are committed to the exterior angels....we’ll just have to work with them.and yes please Oklouise, if you could make the bathroom work in the blank space of the plan I added that would be great. I’d like 2 doorways...I like the option of an ensuite room in quieter months when we have our friends to stay..over summer it can just work as a shared bathroom.(keeping the bedroom side locked.

an ens with two way connecting doors but dimensions will be subject to accurate angles not possible with my vintage CAD program ... the bedrooms are all 3500 x 4500 including the wardrobe and desk/bench spaces
