Several new articles on this subject include “2021: The Rollercoaster Year That Changed Construction Forever”, on page 27, and “Construction Materials Prices”, on page 28. A note of optimism is introduced in “Construction Firms Foresee Growing Demand for Most Types of Projects”, on page 38. “Three Sustainable Materials Set to Disrupt the Construction Industry”, on page 23, informs about new materials that can join the ongoing effort to help the construction industry overcome being one of the world’s biggest carbon emitters. ADUs are gaining in popularity for several reasons, the primary being additional income, providing as much living space as many apartments and condos, and the flexibility to share independent living areas with family members and others, allowing seniors to age in place as they require more care. Our featured project, “Granny Flat”, on page 8, tells the journey of one homeowner’s decision to build an ADU, and page 13, “Garage Addition”, features the garage addition on the same property. And our featured article, “ADUs are Blowing Up”, on page 18 informs about ADUs in various parts of the country. We’re also including our tried-and-true square-foot cost studies of new buildings and renovation projects submitted by your peers. Some of the other projects covered in this issue include: • Broad Creek V, featuring attractive, modern and sustainable housing for low- and moderate-income individuals, consists of 50 units in two locations (page 40); • Hostel 512 (page 52), is budget-friendly, yet comfortable and modern, and its facilities reflect the laid-back attitude for which Austin, Texas, is known; • Charter Oak International Academy (page 31), named after the symbol of American independence, the famous Charter Oak, which is also commemorated on the Connecticut State quarter, achieved U.S. Green Building Council LEED Gold Certification.

However, in a sign of strong demand, building permits increased at a solid pace in January. The January reading of 1.64 million starts is the number of housing units builders would begin if development kept this pace for the next 12 months. Within this overall number, single- family starts decreased 5.6% to a 1.12 million seasonally adjusted annual rate. The multifamily sector, which includes apartment buildings and condos, decreased 0.8% to an annualized 522,000 pace. “The market needs more housing, but chronic production bottlenecks, including ongoing price increases for lumber and OSB, continue to raise housing costs and harm housing affordability,” said NAHB Chairman Jerry Konter. “In fact, the number of single-family homes under construction continues to rise as construction cycle times increase due to delivery delays with building materials.” “While single-family starts dropped in January, the rise in permits, along with solid builder sentiment as measured in recent monthly surveys, suggest a positive start to the year given the recent rise in mortgage rates,” said NAHB Chief Economist Robert Dietz. “The average 30-year mortgage rate increased from 3.1% to a 3.45% from December to January. Fueled by higher mortgage rates and construction costs, declining housing affordability will continue to affect the home building market in 2022.” On a regional basis compared to the previous month, combined single-family and multifamily starts are 2.6% higher in the Northeast, 37.7% lower in the Midwest, 2.0% lower in the South and 17.7% higher in the West. Overall permits increased 0.7% to a 1.90 million unit annualized rate in Supply Chain Issues Continue to Slow Housing Starts Whimsical Roofline Snap-Clad Metal Roof and Wall System Custom Dynamic Blue Altgeld Family Resource Center, Chicago Installing contractor: Progressive Dynamics Architect: KOO LLC Owner: Chicago Housing Authority Photo: hortonphotoinc.com Vibrant Dynamic Blue Snap-Clad metal panels brighten the playful roof shapes and walls of two interior courtyards, invigorating this mixed-use building that houses a Chicago Public Library, childcare center and community meeting space.

Multifamily permits decreased 8.3% to an annualized 694,000 pace. Looking at regional permit data compared to the previous month, permits are 48.3% lower in the Northeast, 0.7% lower in the Midwest, 11.4% higher in the South and 13.9% higher in the West. There are now 785,000 single-family homes under construction, a 26.8% year-over-year gain. There are 758,000 multifamily units under construction — a 14% gain.

In the past, the reasons for building one were to increase the value of the property, generate rental income, or use as a guesthouse. But with increas- ing doubt about care facilities, the prime usage now is to provide a home for the existing homeowners’ aging parents. On this project, the architect worked closely with the owner regarding their vision, as well as the zoning process, which included communicating and selling the idea to neighbors. This neighborhood was developed right after World War II and had remained single family zoning for over 70 years, so the permitting was no small feat. The county allowed the additional dwelling, and others on the street have fallen suit. Since zoning required a kitchen, this was also incorporated into the design.

Care was taken in blending the completed project into the existing neighborhood. A considerable amount of earthwork was required before and after the actual construction. A 4-foot change in elevation on the site in the area of the addition necessitated a swale and a retaining wall to manage stormwater run-off. Flexibility for usage was achieved by building a one-floor dwelling that is ADA compliant, and the exterior stairs at the entrance can be converted to a ramp; adding a house elevator or stair-lift will also be possible when and if needed to access the basement area. The finished basement (with a built-in dehumidifier) boasts a full bath and bedroom/office, with a Bilco walk-out bulkhead for the required emergency egress. The flat features two-zoned heating and cooling and separate electric metering. The cathedral ceiling in the os Courtesy of WL Architecture /March-April 2022 9 The closing in. The basement stairs were extra wide to accommodate a future stairlift. The architect specified a Bilco Egress Window Well System to allow natural daylight and meet the building code requirements for emergency egress in the finished basement area. AZEK trim and vinyl siding were used to de- crease the need for exterior maintenance. Accessible features in the master bath include a no-curb shower. The back view of the flat. living area provides a spacious feel, and the hardwood floors and trim match that of the main residence. Vinyl windows and doors with high R-value, an architectural asphalt shingle roof, and low maintenance exterior with the vinyl siding matching the existing house, a TimberTech - composite deck, and Azek trim were used to reduce the need for exterior maintenance.Next >
