About Designing Homes

Heidi Mortensen Design has provided residential interior design services for the San Francisco Bay Area since 1999,  and is dedicated to the idea that our surroundings have a profound impact on our well being.


Our mission is to work with you to create a home that is a reflection of who you are and what you love.  A home that is designed around the way you live and makes you feel like you’re exactly where you want to be when you walk in the door.


There are a multitude of frustrations that come with a poorly designed space; kitchen cabinets where no amount of careful stacking can make all your pots and pans fit, the bathroom with no counter space, a dimly lit entry. A thoughtfully designed home can bring a sense of joy and ease to everyday life.


We have developed a very personalized and collaborative approach to interior design.  Our top priority is to understand your individual vision, style preferences, and specific practical needs to design a room or home that really works perfectly for you.


Contemporary interior design that encompasses color, warmth, and an eclectic, artistic sensibility is what we are known for. We provide custom designed furnishings working with an array of talented craftspeople, emphasize using local sources and sustainable practices and materials.

We’d love to hear from you!


About Heidi


Heidi Mortensen, principal designer and owner, is known for her ability to listen to her clients, translate their ideas into something more than they had hoped for, and make the whole process fun.


A background in the fine arts coupled with years working closely with the construction side of home remodeling has given Heidi the instinct and technical knowledge to create spaces that are beautiful as well as practical. What comes through in every project is an artist’s special attention to color, texture, and proportion.


When not designing amazing homes for clients, Heidi spends time creating art, practicing kung fu, running, and enjoying the artistic and creative abundance of the city.
San Francisco and the surrounding Bay Area provide endless opportunities to discover art, be creatively inspired, and find unique home design resources. Heidi shares these discoveries through the blog, and on the Facebook page – come visit us there!
