Company Profile

Award-winning Interior Designer Cathy Hay founded Hay Design Incorporated in 2004 with a vision to provide Ottawa with comprehensive architectural design, project management, and prime consultant services.

We are an energetic team of creative and talented Designers, Project Managers and Construction Managers, with a mix of capabilities, expertise and experience. Some of our senior staff have over 25 years in the industry with considerable commercial and residential interior design experience. As Interior Designers in Ottawa, we also have considerable experience working with federal, provincial and municipal government agencies and non-governmental organizations (NGOs).

We’ve deliberately kept our team small, ensuring a rich, collaborative environment so that adequate detail and attention is given to each one of our clients and their projects.

Our team is certainly not afraid to explore unconventional approaches to design challenges. We strongly believe in nurturing a workplace culture where ideas flow and creativity thrives. Our wide variety of skills, backgrounds and personalities mean that you benefit from a complimentary mix of creative design and practical management skills, working cohesively to find the right solutions for your space.

Our Process

All our projects start and end with you. We start by getting to know you, exploring your goals, what’s important to you and what you value. It helps us establish a vision for your project, to determine your objectives, requirements and the functions of the space you’ll need.

Getting as much input as possible from the people who will be using the space gives us key insights. It doesn’t matter if you’re a commercial organization or government agency in Ottawa. It will help us determine your operational needs, the proximity requirements between functional groups and balance your workplace culture with practical requirements.

It allows us to determine your technical infrastructure, capabilities and amenities so you will have a workplace that’s flexible, adaptable and durable. A workplace that features light and colour; that focuses on indoor air and light quality; that has colour and energy; and values health and employee wellness.

You end up with a unique space that reflects your organization’s goals and values, and inspires your team to perform at their best.
