An amazing addition to a family home in Manhattan Beach: Art Barn


The Art Barn project involves an 820 square foot addition to a traditional family home by Oonagh Ryan Architects, located in Manhattan Beach, California. A 545 square foot patio was also added to this home, allowing for indoor-outdoor living that can be enjoyed throughout the year.

The dwelling suffered from an outdated 1980’s addition that resulted in underutilized spaces on the interior along with limited connections to the exterior. The owner wished to reconfigure the floor plan to improve flow through the house, maximize indoor/outdoor entertaining areas, and create a space to showcase an impressive art collection.


This project involves a revision to this family home, removing the old addition and starting fresh with a new building envelope. Enhancing the interior by 70 square feet, it encompasses a kitchen and living area that is directly connection to a brand new patio. Existing rooms on the main level were reconfigured to improve circulation while connecting dining and gallery spaces to the new space.


The design brief was to devise a luminous space with a mix of rustic and industrial inspired materials and details.


An asymmetric roof of corrugated metal, Douglas fir beams and knotty cedar boards enclose a gabled volume that unfolds into the kitchen. The roof floats over a plaster wall in the living area which extends to the patio outside. A break in the roof creates a clerestory window that floods light deeper into the space. 


This modern form creates its own unique identity in contrast to the existing traditional home. The transition between the house and the new space was widened and a walnut cabinet inserted in the opening demarcates the transition between old to new and traditional to modern.

What We Love: This fabulous home addition features barn-inspired elements of sliding panels and barn doors along with the inviting warmth of wood. We are loving the mix of rustic and industrial details, soaring ceilings and luminous interiors courtesy of an abundance of glazing. The indoor-outdoor connection helps to expand this home’s living space to the outdoors, perfect for entertaining.

It’s a very cool place but wish you could see better the overall floor plan
with the existing home. I’m also wondering on insulation on this new section, having lived on the beach for many years.

What a fabulous home. I love the fact that it hasn’t been supersized.

Maybe they do need to supersized it a little bit. Yes, it’s an addition to an existing house…awfully inconvenience to have to exit the structure to go to the bathroom.
