The Château Garden Dossier

Our working plan for turning a blank slate into “The Secret Garden” over time.

Here’s the unglamorous truth: big properties don’t need more ideas. They need sequencing.

This is our working garden plan: the zones, the order of operations, what’s already planted, what we’re doing next, and how we’re avoiding the classic mistake of building a beautiful dream directly on top of future plumbing.

1) The garden brief (what the garden needs to do)

We’re not designing a show garden. We’re designing a family garden that can carry a lot of life.

Here’s what it has to do for us:

  • It must feel beautiful in winter, not only in June.

  • It must have places where children can be children and play without caution.

  • It must become more abundant over time, not more complicated.

  • It must include food, not just flowers.

  • It must be legible. Meaning, it should feel like a series of places with purpose, not five acres of indecision (which is what it feels like currently).

  • And it must be buildable in phases, without needing a full-time Downton Abbey staff.

2) The constraints (the land’s non-negotiables)

These are the things we’re designing around, not against.

Winter reality: bare trees, damp ground, low light. We need structure and color that holds when everything else is asleep.

Slope: parts of the property have a pitched slope, which affects paths, drainage, and where “rooms” can realistically sit.

River: beautiful, but not neutral. We have to consider how it affects humidity, floods in winter, the plant choices, and a few spots where we want to linger and create little ‘viewing beaches’ (and perhaps kayak entry points).

Wind and exposure: we need sheltered moments, so we can still enjoy the outdoors even on mildly windy days

Time: trees, hedging, and slow gardens need a head start.

Budget: phased is the only sane route.


If you want the actual working file, here’s where it begins: our zones, sequence, and the first 90-day plan.
