We just received the building permit for our latest residential remodeling project, the Shou Sugi Ban Timber House, and construction starts now! The renovation and preservation of this River West, 1880s era building will modernize interior and exterior spaces, create additional living space and a connection to the backyard, and add new life to a building that could have easily been demolished.
THE BEAUTY OF SHOU SUGI BAN CHARRED TIMBER
The term Shou Sugi Ban (焼杉板), that literally translates to “burnt cedar board”, is a traditional, centuries-old Japanese technique that involves scorching and blackening timber to prolong the life of the wood by making it resistant to decay, weather and bug infestation. It is also know as yakisugi in Japan – yaki meaning to heat with fire, and sugi referring to cypress. It’s believed that the technique dates back as early as the 1700s and began as a process to fireproof fencing and facades of markets and homes to protect goods from fire.
The process involves lighting planks of wood on fire followed by cooling the timber with water. Next, the charcoal layer is cleaned and finished with a preserving oil and the resulting product reveals a deep charcoal black color with a silver sheen. The final result is a unique cladding material rich in color and texture that is very natural looking and has the ability to capture and reflect light. Light reflection can accentuate a buildings surroundings producing interesting shades and patterns.
Because of its sustainable nature, texture and color, we applied Shou Sugi Ban charred wood on several of our building projects including the Carmen Avenue renovation. When we suggested using the cladding material for this project, our clients loved the idea! So much so, they are going to tackle the job of charring the wood themselves rather than buying a finished product.
STRUCTURE IMPROVEMENTS + PROGRAM
BLENDING BRICK AND CHARRED TIMBER SIDING
The 1880s brick house sits on an irregular, triangle lot with elevated train tracks running at an angle in front of the building. Whenever possible, we salvage the bones of a building to reduce the amount of landfill waste. However, due to deferred maintenance, we are unable to salvage the crumbling facade and it didn’t respond well to the site.
We’re removing the existing facade and replacing it with more appropriate materials for a sustainably designed southern exposure. We’ll install a combination of brick and vertical, charred wood cladding, retaining the look of traditional brick blended with striking detail of the black timber. The Shou Sugi Ban timber is intended to reference railroad ties on the “L” tracks near the front of the house, while providing privacy and shading from western light.
PROGRAMING FOR THE BUILDING
Our renovation began with rethinking the layout of the building’s interior to accommodate our client’s lifestyle. The young couple are creative professionals who need a live/work loft space with an open floor plan centered around a kitchen. In addition, they want a master suite combined with a living space, kids bedrooms and space for guests, and multiple access points to outside.
We’re giving the structure a little boost with a new steel system frame on the first floor, and for efficiency, we’ll build out the second and third floor with a conventional frame. Replacing windows and doors with low-e 3 glass, and blasting the walls with a highly-efficient insulation, will significantly improve the building envelope.
To increase living space, we are removing the existing attic roof, while retaining the masonry side and rear walls to create a third floor. Atop the third level, which will have a flat roof structure, we designed a perfect spot for a roof garden. Over time, the green oasis will flourish with heat absorbing plants that attract beneficial insects while helping to mitigate water runoff to the overall site.
INTERIOR & FLOOR PLAN DETAILS
While the new exterior facade is a dark pallet, we focused on applying lighter, Japanese-inspired, natural materials for the interior. Stepping inside, the interior will be bright and airy with the addition of new windows and an open staircase with two story space at the bottom landing. The large windows and floor-to-ceiling glass folding wall on the first level allows the interior spaces to enjoy ample natural light and air ventilation, reducing the homes reliance on artificial energy. Custom, white oak millwork cabinetry and details will flow throughout the house adding a warm and calming hue.
UPDATED FLOOR PLAN
The ground floor of the house was gutted at some point so there weren’t many obstacles to designing an open living and work space. We positioned the kitchen and dining spaces near the newly enlarged window system to take advantage of sideyard views. The work space functions as a fusion, kitchen photo studio and the amount of natural light is a welcome free light source for our clients.
We’re adding several bedrooms and a guest bedroom to the second floor, and the third floor addition is where the master suite and living area are positioned. Our clients will feel thoroughly pampered in their deluxe master suite with a fireplace, swanky bar and lounging areas. With lavish amenities, spaciousness and a private deck, they might find it hard to leave the retreat-like space.
YOUR BRICK IS SHOWING
It’s hard to resist the temptation to expose brick walls, which impart timeless texture and character to a space. Our clients were interested in exposing some of the existing historical Chicago Common masonry in the interior which takes a little ingenuity.
Considering our current energy code requirements, exposed masonry at the exterior and interior of a wall is nearly impossible. It’s typical for builders to keep exposed masonry at the exterior face and build an insulated furring wall at the interior. We think they have it backwards. Here, we designed an insulated and cement board, waterproof membrane at the exterior side of the masonry. This type of rainscreen allows us to keep the interior exposed masonry surface. And an added benefit to this design is that the masonry will act as a thermal mass in the winter by absorbing and storing heat during the day and releasing it back out into the space at night.
CREATING CONNECTION WITH THE YARD
There is such potential with the amount of side and rear yard space. And in its current condition, the only connection to the yard is a rickety door that opens to an awkward set of steps leading to the yard. Our plan is to maximize the connection between the interior and exterior by replacing the side entry door with a large scale folding glass wall system that really connects to the site’s open space.
The folding doors opening to the walkway merge with the yard creating more useable space, especially during warmer months. The cantilever overhang, that juts out from the second and third floors, provides shade and protective cover during rainy months.
We’re eager to begin work on this project to make some vast improvements to the livability of the space and overall aesthetics. Below are a few photos of the existing exterior and interior conditions, and you can check out our social media platforms for construction updates.
