We take private capital and deploy it into real estate with a tailored focus - delivering high-return strategies through personal relationships and an intensely proactive approach.

Trading since September 2015, Pennine Investment Management specialises in identifying underappreciated, unloved assets with untapped potential.

With a track record spanning more than a decade, we’ve demonstrated our ability to create value across market cycles and asset classes.

A New Name, Not a New Business

Glenbrook has grown into two distinct businesses: development, focused on large-scale residential schemes, and investment, focused on smaller lot sizes and shorter-term value-add.

To keep that distinction clear, Pennine Investment Management now takes the investment business forward under its own name, same directors, same team led by Scott Griffiths, in the same Manchester office.

Pennine isn’t a new business, it’s a new name. We’ve been trading since September 2015, completed over 75 deals, and typically have close to £100m invested at any one time.

We don’t just manage assets, we shape opportunities, refine rough potential, and unlock premium value with precision and care.
