Haggai Home · Building connected communities
Built meticulously.Every time.
Haggai Home is John Martin and Luke Santangelo. We develop and manage the construction of homes, mixed use buildings, and commercial space, and we run every job with the same discipline. What we save goes back into the next project and the neighborhood around it.
Bring us a siteOur mission
Every dollar savedis a dollar backin the community.
Construction is where most community projects lose money: missed steps, loose budgets, change orders nobody checked. We run construction efficiently and meticulously, every time, and we put what we save into rebuilding the community, project after project.
The men whodo the work.
About Haggai Home
Luke Santangelo
Finance and construction operations
Manages property and construction work, and keeps every budget, draw, and payment exact.
What we build
Homes, mixed use,and commercial space.
Homes
Single family homes, rowhouses, and multi unit buildings, new and rehabilitated.
Mixed use
Homes over storefronts that bring daily needs back within walking distance.
Commercial
Retail, office, light industrial, and community space, because connected communities need economic development as well as housing.
How we work
Our own engine,behind every decision.
We built the Haggai Engine to work the way we do. Every site gets the same treatment: zoning, flood, environmental conditions, cost, and the return to the city, on one record, with every number sourced. It is why two people can run projects with the precision of a much larger firm.

In the field
The same discipline,on every job site.
Our supervisors and contractors carry the Haggai Home app on iPhone and iPad. It opens to the work at the address where they stand, holds every contractor to the schedule in the contract, and files the day before anyone leaves the site.
