Stayed within budget and on schedule.Katja's ability to translate our vision into reality was really helpful.We faced some unexpected structural issues, but Katja was very proactive in finding solutions every time.

Katja worked on the design of my house…

Katja worked on the design of my house side extension and delivered the plans very quickly. She carefully considered all my feedback, handled the planning permission process, and submitted amendments to the council as needed.

Her extensive experience and knowledge were evident throughout. Katja was highly responsive, easy to communicate with, and completely transparent about every step of the process.

She is trustworthy, reliable, and I would highly recommend her services.

Thank you so much, Katja!

Efficient, great communicator and gets results

Katja was brilliant to work with and got our design through planning permission really quickly and efficiently.

On top of her speedy and effective worl, Katja was an excellent communicator who somehow always seemed to reply within an hour or so of an email, which was so reassuring.

I wouldn't hesitate to use her again for building regs/planning permission guidance and help and would highly recommend.

Excellent service

Katja helped us obtain planning permission and building control certificate for a kitchen-living room renovation. She went over and above providing helpful advice, responding very quickly to queries and supporting us throughout the process. She was also very reasonably priced.
