Terrapin Construction Group delivers design-build cannabis cultivation and processing construction across Portland and Oregon, one of the most established legal markets in the country. Cultivation and processing facilities typically run $160 to $420 per square foot depending on tier, environmental controls, and extraction. TCG self-performs the insulated metal panel envelope and specialty flooring these facilities require.
Cannabis & CEA in Portland
Oregon has one of the most mature legal cannabis markets in the United States, with a fully licensed recreational and medical program under the OLCC and a deep base of cultivation, processing, and extraction operators across the Portland metro and the Willamette Valley. In a mature, competitive market, facility efficiency and build quality are what protect operator margin.
Cultivation and controlled-environment facilities are envelope, environmental-control, and power problems. TCG delivers them through design-build with self-performed insulated metal panel for the sealed, hygienic, thermally stable envelope, seamless polyaspartic flooring through the Cannafloors partnership, and in-house MEP engineering for HVAC, dehumidification, CO2, and grow-room power. See our cannabis facility construction services.

Processing & Extraction
Processing, extraction, and packaging space with code-compliant occupancy, ventilation, and hazardous-area design.
IMP Envelope
Self-performed insulated metal panel for the sealed, washable, thermally stable envelope these facilities require.
Specialty Flooring
Seamless polyaspartic and epoxy flooring for wash-down grow and processing environments via Cannafloors.
Environmental MEP
HVAC, dehumidification, CO2, and grow-room power engineered for tight environmental control, yield, and Oregon energy code.
CEA & Indoor Ag
Controlled-environment agriculture and indoor food production with the same envelope and MEP discipline.
Why Cannabis & CEA in Portland
Oregon cannabis construction spans indoor cultivation in and around Portland, greenhouse and mixed-light grows through the Willamette Valley, and processing and extraction facilities serving a statewide supply chain. In a mature market, operators reinvest in efficiency, automation, and facility upgrades, and experienced grow-facility construction is a real competitive edge.
Cultivation cost is driven by environmental control, tier of finish, and processing scope, not just square footage. A greenhouse or CEA shell sits near the bottom of the range while a fully controlled indoor grow with extraction reaches the top. TCG budgets from the envelope and MEP program during preconstruction. See our guide to value-engineering a cultivation facility.

Does TCG self-perform the envelope and flooring for grow facilities?+
Yes. TCG self-performs insulated metal panel envelopes, the sealed, washable, thermally stable core these facilities require, and delivers seamless polyaspartic and epoxy flooring through the Cannafloors partnership, with over 1,000,000 SF of IMP placed nationally.
Can TCG build indoor, greenhouse, and mixed-light facilities?+
Yes. TCG builds indoor cultivation, greenhouse, and mixed-light operations, matching envelope, HVAC, dehumidification, and lighting infrastructure to the cultivation method and Oregon energy code.
Can TCG build controlled-environment agriculture in Oregon?+
Yes. Controlled-environment agriculture and indoor food production use the same sealed envelope, environmental controls, and power discipline as cannabis cultivation, and TCG builds both with in-house MEP engineering.
How long does a cultivation facility take to build in Portland?+
Most cultivation and processing projects take 7 to 14 months depending on environmental controls and processing scope. Long-lead HVAC, dehumidification, and grow equipment should be procured early, and design-build sequencing protects the schedule.
