Well I know you want to be true to the house & reuse what you can but I would probably go with a more modern style like the stainless wire and timber top rail rather than dowels or timber for the infill. Be mindful of building code for the infill as horizontal is climbable and has to be very close together. There is so much upkeep in timber & if you go with the vertical metal rod look with the timber top plate maybe...? I am not an expert on any era or style though I know you will have a preference in mind & I would go with that. Look at the big picture of how your house will look with a change of paint (are you painting the house?) & for me it was about making the 25 year old house more contemporary. We love it!

Omg..I love it ..very, very jealous

Awesome work!!

Like the idea, will be a fabulous area for this lucky family. Just too much the same colour for me. Hopefully lots of pillows, pots and plants will add some life to it.
