Portland Phased House

ph2 p02

This project is designed to make new home construction affordable for more families. It eliminates the need for owning two properties at the same time, or expensive temporary housing, and allows the homeowner to proceed with construction when it fits their budget.

Phase One of the project starts as soon as the family has closed on their new property. They move into the existing house on the site, and proceed with the demolition of the existing detached garage. In its place, a new garage is built. This garage includes an Additional Dwelling Unit (ADU), located to the side of, and above, the garage.

The ADU is built to the maximum size allowed by Portland’s ADU program, and can be rented out for additional income when the main house is finished. While the ADU is a one bedroom unit, additional space in garage can be utilized by the family while their new home is under construction.

The ADU has a generous entrance and stairway, with its bedroom and bathroom on the first floor, and open living space on the second floor.

With the living space on the upper level, views and light are enhanced. The living space opens out to a roof garden.

The ADU is treated with similar architectural features as the main house. This maximizes the family’s enjoyment of their  temporary home, and allows a higher rental price down the road.

The main views from the ADU are oriented away from the future house.

In Phase Two, the existing house is demolished, and the new house is built. As can be seen above, the two buildings form a cohesive whole. A large, south-facing courtyard is defined, and indoor-outdoor living is developed.

The street facade captures the entire buildable width of the lot. While the house is a simple rectangular volume, varying levels of openness and enclosure interact with light and shade, developing a lively engagement with the neighborhood.

The entrance from the street is brought to life with light, shadows, reflections and transparency.

The living and dining room are animated with light filtered through trees.

The living room is open to the east and west, with ample light throughout the day. The home’s terrace is seen on the right.

While somewhat open to living and dining, the kitchen is a clearly defined space. It opens onto the terrace, and has a western view of the back yard as well.

The stair to the second floor is enlivened with a generous skylight, and open construction.

From the second floor master suite, the upper part of the stair is glimpsed, along with a view of the roof garden.

Indoor-outdoor living in the master suite. Should the owner desire, the roof garden space could easily be converted to a third bedroom.

Focus on the terrace, with dappled light and filtered views. A generous glass covered walkway shelters access from the garage to the kitchen, and creates an outdoor space that can be enjoyed in the rain.

Site Plan

The site and floor plans above show the house in its finished state. The main house is 1,600 square feet, with two bedrooms; and the ADU is 790 square feet with one bedroom.

This house is designed for a typical Portland east-side lot – 50′ x 100′, relatively flat, and with an existing house and detached garage. Its principles can be applied to other lot types as well.

When designing this house, I was inspired by the idea of helping architecture lovers of moderate means achieve their dream of building their own house. I’m looking forward to getting to know your particular dream.
