Overview
Cushman & Wakefield, as exclusive advisor, is pleased to present the opportunity to acquire 3601 Haven Avenue (the “Property”), a single‑tenant industrial/R&D property located in Menlo Park, California, one of Silicon Valley’s most supply‑constrained and highly sought‑after infill submarkets. The Property is 100% leased to Mainspring Energy through August 2032, providing stable cash flow supported by a high‑quality clean‑technology tenant.
3601 Haven comprises 20,216 square feet of high‑functioning industrial/R&D space designed to support advanced manufacturing, engineering, and technology‑driven operations. Located near the heart of Silicon Valley, the property benefits from excellent regional connectivity, proximity to a deep technical labor pool, and immediate access to many of the world’s leading technology and innovation companies.
Investment Highlights
100% LEASED TO A CLEAN ENERGY TECHNOLOGY COMPANY
The Property is fully leased to Mainspring Energy, a rapidly growing clean‑energy technology company focused on advanced power generation solutions. Backed by prominent institutional and strategic investors, Mainspring Energy serves a broad range of commercial, industrial, and utility customers seeking reliable, low‑carbon energy systems. Founded in 2010, the company recently completed a Series F funding round of $258 million, for a total of ~$739 million capital raised. In 2024, Mainspring was awarded an $87 million grant by the U.S. Department of Energy for manufacturing expansion. Mainspring has been at the Property since 2018 and recently signed a lease renewal to August 2032.
FUNCTIONAL INDUSTRIAL / R&D DESIGN, LOW CAPITAL REQUIREMENTS
3601 Haven offers efficient single‑story industrial/R&D space well‑suited for manufacturing, engineering, and technology‑driven operations. The building’s configuration with 17.5’ clear heights supports high‑value industrial uses that remain in exceptionally strong demand throughout Silicon Valley. The Property has been well maintained, minimizing near‑term capital expenditure requirements.
STRONG LONG-TERM TENANT DEMAND, DIMINISHING INVENTORY
Industrial and R&D assets in core Silicon Valley locations have experienced persistent tenant demand driven by innovation, electrification, clean energy, and advanced manufacturing trends. At the same time, available inventory has continued to decline as industrial sites are redeveloped or converted to alternative uses. This imbalance between demand and supply has reinforced long‑term occupancy stability and rent growth potential for well‑located assets such as 3601 Haven.
STRATEGIC MENLO PARK LOCATION
Menlo Park is among the most supply‑constrained industrial markets in the Bay Area, benefiting from extraordinary barriers to new development and sustained tenant demand. The Property is located between Silicon Valley and the Peninsula, offering immediate access to U.S. Highway 101, Interstate 280, and other key arterials. Its location provides direct connectivity to major employment hubs of Menlo Park, Palo Alto, Redwood City, and Mountain View, while drawing from one of the world’s deepest pools of talent.
