Green Design Innovation

Welcome to Green Design Innovation, an international approach to interior design.



Remodeling and Home Design

Hello! I am Catherine Montague.

Green Design Innovation, an international approach to interior design, is located in Sewickley, near Pittsburgh.

I look forward to helping you create your dream in Sewickley, Pittsburgh, Naples, Paris or where ever you are.

At Green Design Innovation we strive to make your interior design experience:


We want you to have a wonderful interior design experience creating the home or office of your dreams. Your environment represents who you are and we love to amaze you with the results.


We take the stress out of the process. You live your life, and we take care of the details for you. Depend on us to make it seem effortless.

No Hidden-Fees!

Establishing a budget for your project will keep it from taking on a life of its own.   As your professional interior designer, we guide you through the process so you know exactly what results you can expect for your investment without expensive surprises.

Virtual or in Person – Convenient for You!

Life is busy and free time limited. Communication is key to our success with client projects.  We keep you abreast of your interior design project in person or virtually.

Necessity or luxury?

A good design is a necessity that will allow you to come home and relax in surroundings tailored specifically to you and your family’s lifestyle.

Do you want your employees to be more productive in a well-planned office? Do you want to feel successful as you spend your day at your desk? Then good interior design is a necessity.


Imagine the excitement of going home to a beautiful retreat, and create memories with your family in surroundings tailored just for you.
