Hello @meera,
Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about your butler kitchen.
Thank you for sharing your floor plan with us. Can you please tell us the size of your butler's kitchen? Can I also please request for a photo of the butler's kitchen if possible? This will give our members a better idea of its layout. We can then make recommendations on cooktop and basin location.
I would also like to ask if you'll be installing a rangehood in that location? Have you chosen your cooktop and basin appliance? If you have, please let us know the type and model you've chosen for the area.
If you have any other questions we can help with, please let us know.
Eric
