If you’ve had professional plans drawn up ask them to produce view of the front of the house.

Is this a single story building

its two storey

Without seeing the floorplan /3 D I would like the balcony as long as the room is big enough without the balcony. I assume that there are other living room/s downstairs

Is there a view from balcony? Apart from traffic and neighbours. In reality would you sit outside on the balcony? Would more room inside be beneficial?

Being south facing I would use the floor space inside. Architectural treatment can be addressed

I would go with the balcony, it will reduce the tall box look and will still give lovely light and a place to sit and enjoy being outside without having to go downstairs.

facade is facing street opp to another neighbor balcony.

Looking at your plans the Balcony is East facing with openings on both North and south sides. If you prefer the extra space go without the balcony, the upstairs exterior would then be white without the grey coloured Piers?

So…if you have no views of a park or river or ocean, and just the street and neighbour, then I would not have a balcony. You probably won’t sit out there in winter because it will be too cold. Maybe hot days away from the sun, but having space internally would be better and you could just have windows that can open up for fresh air.

Example of facade option.

Or these which are a bit closer to the design of your home with front door below upstairs window.

Great. thanks a lot for your time Dreamer and Siriuskey :-) appreciate it. i like tall pillar upto roof ceiling, so will addd windows in front and sides to make it like a sunroom

Sounds like a good plan.

siriuskey Great thanks and really appreciate your time playing with facade :-)
