Building systems and technologies incorporated into Make It Right homes
represent a significant milestone in environmentally sustainable
construction of affordable, energy efficient and healthy homes. For the
purpose of determining the most effective model for efficient homebuilding,
the methodologies listed below are currently being employed.

Construction Methodologies

Site-Built (Traditional) 1631 Tennessee, 1720 Tennessee, 1843 Tennessee
Site-built construction, optimized by the use of advanced framing techniques
and high performance insulation, is a viable methodology for construction in
the Lower 9th Ward. An added benefit of using traditional construction
techniques is workforce development, including the creation of local jobs
and on-site training for skilled trades, with an emphasis on green building
techniques – a valuable and increasingly marketable skill set for residents
of the Lower 9th Ward.

Modular 1632 Tennessee, 1809 Deslonde
Modular homes are constructed using modules or panels built in a factory and
shipped to a construction site where they are assembled, typically by crane.
The benefits of indoor, assembly line modular production include increases
in speed and efficiency as well as a reduction in waste. Additionally, the
building materials and process are typically protected from prolonged
exposure to the elements, unlike the traditional on-site construction
process. Once on site, the modules can be assembled more quickly than
traditional stick built homes.

Panelized 1744 Tennessee
In many ways similar to modular construction, panelized homes are assembled
from prefabricated panels constructed in a climate-controlled facility and
then shipped to the jobsite for assembly. Component panel types include
simple pre-cut floor and roof trusses and strong and efficient structural
insulated panels (SIPs). Standardizing certain material types, board lengths
and systems across the Make It Right designs could result in dramatic cost
and time savings for the project. Because panels are typically built in
standard 4’ lengths, they minimize wasteful offcuts. Additionally, benefits
in quality control and speed of construction can be achieved by developing a
customized panelization system that can be implemented by local custom
builders. A recent NAHB study found that construction of a 2,600 SF home
with trusses and panels used 26% less lumber, generated 76% less waste and
was constructed in just 37% of the man hours of a similar stick-built home.
