About Us

Spanning the boundaries between inside and out

Tierney Conner Design Studio weaves together the fields of Architecture, Interior and Landscape Design, to produce projects that span the boundaries between inside and out. We provide a unique service that considers all living spaces in an integrated manner. Our strength is in creating spaces that are site and situation specific to each house, garden and business.

Maximizing living area

Many of our projects focus on maximizing living area, by expanding activities outdoors, or by finding opportunities within existing spaces - turning limits into assets. While our designs are modern in vocabulary, our projects are often renovations to existing structures with a notable character or quality worth preserving. By merging traditional buildings with updated interventions, complimentary details and refined layouts, we infuse modern style and function. We work within functional and financial parameters to create innovative designs that allow our clients tot take fullest advantage of their existing structures and property.

Creating inspired designs for everyday living

We create inspired designs for every project, regardless of size. Through artful use of space, views, materials, texture, color and seasonal fluctuations of light and vegetation, we highlight the simple and enjoyable beauty found in everydaty life. We provide our clients with a wholistic approach to living, working and playing that capitalizes upon, and reveals, the unique qualities of a place.
