Fantastic words by those who put their trust in us for their projects

As I was looking for architects and interior designers to remodel my apartment in Lisbon. I sent emails to several companies. Since day one, I decided to choose Helder Calça. Both Helder and Bruno were extremely thoughtful and professionals from the very beginning.
Their dedication to this project exceed all my expectations. I don’t live in Portugal, but my com- munications with Helder were always easy and fast. I would receive updates on the remodeling on a daily basis. The work was gorgeous and I was thrilled with the result.“

During all the process I was sure to count on all the support from Helder who was constantly worried about all the details, as well as to match the results with my primary expectations. An enormous thank you to all your work.”
