A thing is right when it tends to preserve the integrity,
stability and beauty of the biotic community.
It is wrong when it tends otherwise.

Montage Design & Building
Montage-- any combination of disparate elements that forms
or is felt to form a unified whole”
“Montage is about prefabrication and assembly...the
dual nature is identified by the dichotomy between
montage as a construction strategy and montage as
a aesthetic strategy.
…a way of thinking about architecture as an
instrument rather than a monument..”
Charlotte Bundgaard

A Better Way to Build
Montage = Combination of Disparate Elements that Forms or is Felt to Form a Whole, Unified, Singular Image
•
Build time will be 20 days vs 100 – 260 days
•
Off-Site Impact: 75% vs 10% to 30%
•
Safe working conditions
•
Consistent working conditions
•
Good Jobs:
•
Discipline, Training, Skills
•
Empowerment; low turnover
10OCT14
A Better Standard of Cost & Finance
Cost cut; standards raised
•
Architect-developed custom home design will be free
•
Cost estimates will be accurate
•
Advantaged financing available
•
Higher standard at a price competitive with existing homes & new construction
•
Total cost of ownership a fraction of competitive alternatives
•
Home value increased with brand standard
“This beautiful Tedd Benson (Unity) home…”

2. Lagom Ethos
Lagom (Swedish) no direct English equivalent, meaning “just the right amount.”
Not enough is as important as not too much.
The Swedish-English dictionary defines lagom as "enough, sufficient,
adequate, just right". Lagom is also widely translated as “moderation", "in
balance", "optimal" and "suitable" (in matter of amounts). Whereas words
like "sufficient" and "average" suggest some degree of abstinence,
scarcity, or failure, lagom carries the connotation of appropriateness,
although not necessarily perfection.
--”Enough is a feast”
--Optimizing is better than maximizing
--What is the best affordable option?
