SW Portland Residential Addition

 

 
This residential project represents a design that provides both beauty and structure.  Miller Consulting Engineers performed the structural design services for this project which involved constructing a residential addition below the existing garage.
 
In order for this space to have a light and open feeling, the architectural design called for full height windows on three sides of the structure.  This eliminated the use of conventional wall framing as a way to support the detached two-car garage above.  The use of timber frames inside of the structure allows the architectural design to function with the structural needs of the building.
 
To withstand wind and earthquake loads the design is further complicated by the steep site below the below the building.  
 
The floor addition below the existing garage required a complete structural analysis for the entire building, with strengthening measures to be provided to allow the structure to meet the more stringent requirements of the current code. 
 
Due to the architectural requirements of the new space, some of the existing timber frames were removed, requiring further strengthening measures to be taken for the remaining structural elements.

 The architectural design of this project was provided by Jeff Stern of Insitu Architecture and was constructed by Right Arm Construction.  The success of this project is a reflection of the teamwork and skill of the design and construction team.
