What about 2 outdoor love seats facing each other, small round table in the middle, and a suspended swinging bench from the edge rafter of the patio? Most of the larger swinging benches can seat up to 4. That way, if you have fewer guests and don't need the swinging bench, you can pull it off and maybe swap in some chairs from inside your home and put the bench in your garage to open the space a little more...and if you have kids there, they'll love the swinging bench, as will adults. It's a win-win!

Bit of a circle thing, the engineer will have trouble commenting on what you plan to do without drawings of the existing and proposed. Never met an engineer who could not work their magic on any structure, but there will be simple and cheaper methods and then there can be some super expensive ones. Builders and engineers should be communicating as well. If i were you, i would have identified a builder, get a good architect to work with you, your budget, the builder and engineer, and town planner if this requires DA approval. Overshadowing is the shadow your structure casts on the neighbors property. Overlooking is when they can see into your property, some councils have means to prevent this and the last to build normally has to screen their windows to prevent overlooking, some require only high windows, not all councils and not all property sizes will be affected. If the architect draws in a 3D package it is a simple matter to show you where the shadows land at any time and day of the year, based on you address. If allowed to build that top story, they can show you if you shade your pool. This is a big investment from you, most likely you would be living with the results for years, i would imagine that you would want the best outcome for your family, and to engage professionals would be the way to achieve those outcomes. Thoughts and ideas from forums like this are great, but sometimes they are not aware of the outcomes of comments which might affect your whole project, and councils around the country all have different requirements. Check and check again. What is allowed in Brisbane with height and upper floor window sizes on smaller blocks, will not be allowed in Melbourne, or Sydney councils. Shadowing while really not an issue in Brisbane, will be a huge issue in Melbourne, so get a local team. Ros

Your mockup scheme is similar to our master bathroom we just completed - photo below. I know you mentioned storage being a concern - our mirrored cabinet has offered an amazing amount of storage in a very small space and also helps bounce light around. I was worried about black taps etc too so we kept chrome fixtures but added in a matte black candle and black potted orchid to create a similar effect which we can change out later on. Our floor tiles are dark but because they are semi-polished they actually bounce around a lot of light and don't make the room feel dark if that is a concern. We also have a huge fiddle leaf fig in the corner (not pictured) which adds a really nice feel to the space - a plant like that could help bring in the outside greenery in your bathroom. Instead of the storage tower you have to the left of the vanity could you do say some floating wood shelving, possibly with baskets added for more hidden storage? You could also bring in the 60s theme with what you displayed on there eg. photos as you mentioned? In regards to the window - a previous house we lived in had a window at about shoulder height in the shower - as well as letting in heaps of light it was amazing for storing toiletries etc!

Hi there, "you're gunna need a bigger house", as Retro said the garage would need to be used for a snooker table but they do come in all sizes starting around 2130 x 1070. I have done rough floor plan for you suggesting a change of entrance to the lounge so that it expands the family when the doors are open. The snooker table is suggested for the entertaining area as this will give space around for using the cue's without hitting walls, ie: two open walls that could have blinds or shutters to close it off when not using that space, not sure what your climate is. Hope this gives you some ideas cheers
