    Don't just take our word for it — hear from homeowners who have transformed their spaces with zHeight.

    "They helped me with my design for my remodel. Came up with some great ideas on layout to make best use of the space! Communication was great as well as sticking to the timeline they proposed. Can't post pics yet as I am picking up permit on Monday to start the remodel."

    Benjie Craig

    "zHeight made our bathroom addition so easy! The plans were clear, approved quickly, and the team kept everything on schedule. Super professional and affordable -- highly recommend them!"

    Tameesh

    "I highly recommend Sankar and Zheight team for any design and permitting need. Their team is super reliable, easy to work with, and really know their stuff. They make the whole process smooth— from planning to getting approvals."

    Reddy P.

    "From working with a prior architect, who was MIA and hard to get a hold of. Working with Vidushi and her team truly delivered a sense of hope in this stressful process! My revised plans were approved with only a minor planning comment for San Jose and zero building comments, which speaks to the quality and accuracy of their work. I would highly recommend zHeight for anyone looking for a smooth and efficient permitting and design process."

    Fang T., San Jose, CA

    "ZHeight helped us prepare whole-home remodel plans for several investment properties. They came out quickly to generate architectural drawings, and we iterated on the remodel plans leading up to the submission and response to city reviewer comments. The projects were approved and I would enthusiastically recommend Vidushi, Ajaini, Sankar, and Ever to anyone looking for a cost-effective and high-quality partner for remodel plans."

    Gregory P., Newark
