How the greenhouse range is combined: low end from the middle of the guides' lows, high end from the middle of their highs, typical from the middle of their averages (a range's midpoint where no average is given). Figures read on each guide's page on October 9, 2026.
Labor share used: 50%. None of the guides splits labor out for this job, so this share is Koira's working assumption for patios, decks and outdoor living work. State factor: the state's median hourly wage for construction and extraction workers over the national $28.63 (BLS, May 2025), kept between 0.7 and 1.4.
