With option 2 flip laundry and powder room/wil to move powder room door. The study will be very dark so consider glazing in one wall. Will you move front door out to accommodate the moved staircase?
In all options add a door out of kitchen to side /front lane . If your letter box is out there it will be useful. Don’t forget the intercom.

@Kate I hadn't thought of flipping the Laundry and Powder in Option 2 as I was trying to keep the Nook and Bed 1 end more private. But yes that's an option to consider.

The entry would need to move forward. Door from the Kitchen is a good idea.

A door into kitchen where the east window is, would be beneficial. Why aren’t you a fan of open glazing with the corner stacker doors? The original design in my opinion is good. Having the open stacker doors that fold back, will NOT make the alfresco feel like a carport. If this is a real issue. Then have two separate glazed areas, with a corner wall. This would also be a cheaper option because there would be less structural engineering required.
You will make the alfresco area too enclosed by moving the scullery and creating a solid wall on the narrow end. Why is it an issue to walk past a study nook? If you don’t want the paperwork on show, install pocket doors that can be closed when required. I have attached examples of open corner stackers or the alternative with a corner wall.

Having the dining and lounge offset from the kitchen could be an advantage. Your not directly looking at the kitchen mess while entertaining from the dining room table. The dining, is not “in” the kitchen.

I do like opt 3. I didn’t see that last night. Great study space. Need sliding door from kitchen to alfresco or slide alfresco further north and let sun in to kitchen in morning

@dreamer The internal corner with glazing just gives me the impression of a section being cut out vs the rectangular section. I also like the direct connection between Kitchen and other areas rather than be semi disconnected. Kitchen and cabinetry makes the space for me.

I see what you are saying about making that wall solid though.

The nook for me will never be pretty. It will have a PC, a printer, tech, mess, a proper desk chair sticking out..... I realise I'm probably pushing the use of the Nook there! Thank you for the images.

@Kate I like that study option too. Only issue is the reduced front yard entry space which may seem pokey to walk through there. I created some basic 3d and walkthroughs and realised the space in the Scullery and Study shown in the previous images was misleading. These images give a better idea of space. Can't attach the walkthroughs.

Tell me more about the laneways. How wide, how many garages. Is it a through lane or dead end. Will you have a fence and gate and what height

I assumed your study nook is about 1800mm to 2000mm wide when I was looking at your plans this morning. This is a good space. Pocket doors which fold back into the side walls would be a good solution to cover your mess when required.

Your 3d renders reinforce my comment about not having a solid wall on narrow part of alfresco. The alfresco will feel too enclosed. And that wall will also be the north side. You want glazing on that side, not a wall.

The third option is good also. But since your land area is tight, do you want to take up so much floor space with a study room?

Part of consideration is sunlight to your open space. Think about how you will use each space inside and out. There will always be compromises. Also note big glass areas incl doors are expensive and less energy efficient. Your study needs to be big enough for your needs, noting printer could be in a diff space

my suggestions include off street parking for close friends and family, narrow courtyard along eastern side and, subject to local regs, i would also have a courtyard fence along the north side for a more private "front" garden and entry gates with intercom through alfresco and drying area on the south side

@Kate The lane is 5m wide and is a through lane, with a 90 degree turn. As far as rear subdivisions with garage facing the lane, there are only a handful, but many of the older properties have their garage in the lane. There will be a fence of 1.8m height. I have also just learned that there is some level of street parking on the main street, so now considering eliminating the entry door from the lane side and adding one to the south side.

@dreamer Thanks for the images. I do like that second one with the extra depth and would probably be happy with it if it was along a side wall. It's 2.1m wide and there is 1.2m between the nib walls and the wall behind. I'm still concerned with it being an eyesore in that 95% of the time that it wont be closed, but will give it some serious thought.

@oklouise Thanks for the layout. I do like the way you have changed up the entry and it's given me some things to consider. The Alfresco would need some connection to North with the rest of the open space for the morning sun rather than being separate.

morning sun should come in from the east to the alfresco until about lunch time and panels of transluscent roofing would also improve lighting in the alfresco

True that would be good in the morning but I'm a bit hung up on the disconnection from the open space. It could work if I can wrap my head around it.

Swap pantry and study for alfresco

Study could be big enough for spare bed. What is happening upstairs. Great the lane is 5m. Is their clear view to access street? How far along lane are you?

Theres approx 10 houses on either side of the long stretch of the lane and I'm in the middle. Upstairs is the teenage zone. 2 bedrooms plus a 3rd bedroom/study, and an activity/lounge.

I haven't strayed too far from the last design yet because I'm really starting to like the cleaness of this layout. Have added the entry to the south side instead with a dropzone. The old entry has become a garage store. While it looks excessive, space there is always usefull. I really like the stairs combined with the entry on the south, but the small study is no longer a nook and more of a cupboard so I'm thinking it cannot work there without a window.

The set up of your land, with pedestrian access to Main Street address, is a common subdivision in Perth. It is very common in the older suburbs with larger long blocks. The new home is built on the lane way with garage, and a walkway for pedestrians from the street address side. There is actually quite a few that have made the pedestrian access a feature for family and guests.

..examples of the common concept in Perth

Great finds! I see they all have the front door on the lane regardless of the street address being the other. I'm just struggling to understand who would ever use my front door if I have it on the lane. Visitors using my street address would always have to come down the long lane and people familiar with the house could please themselves, but would still likely come down the long lane due to the parking being on the main street (contrary to my previous statement that there wasn't any). Everyone does seem to do it though. I guess it's to just give the house a proper frontage?

I agree, you don’t need a “front door” on the laneway/garage facade. I would have the double garage with internal access into the home, AND a enclosed open area with a gate, with access through your alfresco area into the home. In Perth, there is no planning requirement for a front door on the lane way access. Definitely personal choice.
