Home Additions

The living room transformation was part of a kitchen and master bathroom project. The mezzanine was added to be a home office for the husband and wife, adjacent to the master suite.
Kitchen Remodeling4 photos

Kitchen Remodeling

1970s home with the original kitchen was updated with new appliances, cabinets, countertops, and flooring. Lighting was improved, LED fixtures, all controlled by dimmers.
Bathroom Remodeling4 photos

Bathroom Remodeling

The original 1970s master bathroom was landlocked, but we still found a way to enlarge the shower by borrowing 2 feet from the adjacent guest bathroom. The homeowners wanted a Japanese look and feel in the new bathroom, which was achieved with a monochromatic color scheme.

Accessory Dwelling Units (ADU's)

Sisters wanted to build an ADU for their parents, a separate home that's connected to the main house. The ADU had to be wheelchair-accessible for the father, and the parents wanted a full-size kitchen with an eating area, a living room, two bedrooms, two bathrooms, and a laundry room. The local building-planning department established a 900-square-foot maximum for all ADU's; the parents' new home will be 897 square feet. Construction is scheduled for summer of 2019. Virtual-reality renderings helped the family see what the finished project is going to look like.

Accessible Design (Aging-in-Place)

The 1970s existing powder room was transformed into a fully-accessible bathroom with a roll-in shower, adjacent to the entry hall. The new color scheme blends well with the existing home, yet has an updated look and feel.

Basement Remodels

The typical basement had ducts, pipes, and wires, a concrete floor, and exposed framing. A new bathroom and laundry room were added for improved function and a definite improvement in the couple's lifestyle.

New Homes

A Frank Lloyd Wright-inspired home with art deco features was a dream come true for a mature couple. It was designed for accessibility and energy efficiency, using insulating concrete forms for the exterior walls. The home has hydronic heating throughout. LED lighting is controlled by a whole-house switching system.
