01 · The Vision

A nest in the tree family — the first of many

Within the first platform rising through the Mulberry's canopy lives an invitation to every child who has ever looked up at a tree and wondered what it would feel like to belong there; within that belonging lives the whole garden, and the whole neighborhood, already at home.

The Children's Magical Treehouse is an adventure play space and a wilderness learning space, both at once, both fully. It is built from raw Black Locust cut trees — posts rising from the earth like the forest itself — holding two levels of Black Locust platform and Black Locust railings shaped into a nest. The nest is the form. The nest is also the feeling: held, safe, alive, looking out at the garden from inside the canopy.

This is the first treehouse in what will become a family of them, linked by netting bridges as Children's Magical Garden grows and as the tree family grows with it. Every future treehouse begins here, in this first nest, in this first Mulberry.

AreshEarth carries the design, the community process, the build leadership, and the ecological imagination. Roderick Romero brings his lifetime of treehouse wisdom as adviser — the one you call when you want to make sure the nest will hold, and hold beautifully, for generations.

CB3 Resolution · December 2025

Manhattan Community Board 3 formally resolved to support the Children's Magical Garden Capital Improvements, including the Children's Tree House Installation — built to the highest safety and engineering standards with minimal impact on roots through helical anchoring. CB3 urges NYC Parks, NYC DEP, NYC DCLA, and GreenThumb to work collaboratively with CMG on this project.

02 · Architecture & Landscape

Raw Black Locust, two levels, a nest in the canopy

The structure rises from the earth on raw Black Locust cut-tree posts — naturally felled, naturally shaped, planted into the garden on helical piles placed carefully beyond the Mulberry's root family. Two Black Locust platforms, one above the other, create the levels. Black Locust branch railings, woven and lashed, form the nest wall: curving, organic, holding. Rope netting <¾" spans between the railing branches as the inner safety mesh. The whole structure breathes.

Freestanding and tree-independent, the treehouse lives beside the Mulberry and Maple trees, a neighbor rather than a burden. And it is the first: the anchor treehouse from which netting bridges will one day reach to the next platform, and the next, as the garden's tree family grows.

Materials — ecological and beautiful

Raw Black Locust cut-tree posts
The uprights that hold everything. Naturally felled Black Locust, shaped by hand, speaking the language of the forest floor that children recognize before they can name it.
Black Locust platform decking and beams (two levels)
Solid, warm, endlessly durable. No staining, no sealing, no chemicals. Just the tree — the same tree the posts came from, the same tree family the Mulberry belongs to.
Black Locust branch railings, nest-shaped
Curved, woven, organic. The form that says: you are held here. You are safe here. The nest is real. Every railing branch was once a living thing, and the shape remembers that.
Rope netting <¾" mesh — marine-grade
The inner layer of the nest. Woven between the branch railings as secondary safety containment. Child-safe gap dimensions per NYC Building Code requirements. UV-treated for longevity.
Helical piles (galvanized steel)
The foundation that lets the tree family keep living while the platforms rise above. Compact machine installation, no excavation, removable. Placed beyond the Mulberry's root family.
Living plant integration — willow whips and native climbers
Woven into the structure over time. The treehouse, like the garden, grows. What begins as a nest becomes, season by season, something more tangled and more alive.
Netting bridge anchor points — designed in from the start
Structural anchors built into the first treehouse on day one, so the bridge to the next platform is already waiting. The future treehouses begin here, in this first nest.
03 · Permitting Pathway

Working with the city, one careful step at a time

Multi-level height and public access place this project in the DOB permit required category. The goal is classification as an "Educational Platform / Adventure Play Amenity." Three tracks run in parallel — DOB structural, NYC Parks/GreenThumb, and arborist tree protection — with the CB3 resolution as warm backing for all three.

01
Paul Castrucci Architects — first call
LES neighbors on Rivington Street; 30+ years of mission-aligned DOB experience. Start with a neighborly conversation, not a formal RFP. Ask about the architect-of-record role and the pro bono possibility. This call is the key that opens the whole track.
Schedule now
02
Certified arborist survey — root mapping of the Mulberry
Map the critical root zone (1 ft radius per inch of trunk diameter). Arborist fees were court-granted in CMG's legal victory — a prior working relationship exists through attorney Ben Burry. The arborist report is the strongest leverage point with both DOB and Parks.
Contact Ben Burry for referral
03
Letter of Inquiry — Manhattan Borough Commissioner, DOB
Framing: freestanding post-and-beam; never attached to trees; helical foundation; educational + adventure play use for children; CB3 resolution attached. Draft in collaboration with the architect consultant and the summer intern/s.
After Castrucci consultation
04
NYC Parks / GreenThumb coordination
GreenThumb notification required for semi-permanent structures on Lot 19. Frame as "Living Classroom / Adventure Nest" — the 6BC pathway. The CB3 resolution is warm backing here too, and it's already signed.
Parallel track
05
Engineer's stamped drawings (PE)
Live load capacity, guardrail compliance (42" height, <4" gaps), helical pile specifications, and — critically — netting bridge anchor points designed in from day one so future bridges are structurally sound from the start.
After DOB initial response
06
Helical pile installation — Techno Metal Post
Compact machine that fits through a standard garden gate. Rebar probe soil test first. 5–7 piles placed beyond the Mulberry's root family. No concrete, no excavation, no harm. Installation follows permit approval.
CB3 endorsement already secured
04 · Summer Intern/s — Starting June 24

Calling curious, creative, mission-aligned collaborators

The treehouse needs hands, and the hands need a project worth giving themselves to. A summer intern joining AreshEarth on the Children's Magical Treehouse gets to research, design, advocate, and help build something that children will climb for decades.

Beginning June 24, 2026, AreshEarth is welcoming one or more summer interns to support the Children's Magical Treehouse project. This is not a research-and-report role. This is a real project in motion, with real community partners, real permit tracks, and real build days ahead — and the intern/s will be part of all of it.

What intern/s will do

  • Lead the pro bono architect search — research who is aligned, who has community garden or ecological play structure experience, and who would be genuinely excited to be part of this specific project. Draft outreach emails and the AIA NYC pro bono project brief.
  • Research the 6BC Botanical Garden permit pathway in depth — what exactly was filed, how the structure was classified, who the architect of record was, and what can be replicated for CMG.
  • Support the DOB Letter of Inquiry — research, structure, and co-write the formal inquiry to the Manhattan Borough Commissioner.
  • Help coordinate the community design day — logistics, outreach to LES families and school partners, documentation, and follow-up. The day the neighborhood names the treehouse.
  • Support "Name a Branch" and "Steward a Tree" campaign launch — content, outreach, and coordination. Both can be live before the permit is finalized.
  • Attend site visits at Children's Magical Garden and contribute to build-day community energy when the time comes.
  • Bring their own skills and curiosity to whatever the project needs that week — this is a living, growing project and the intern/s grow with it.

Who we're looking for

  • Students or recent graduates in architecture, landscape architecture, urban planning, environmental studies, community design, or related fields — or anyone with a genuine passion for any of the above.
  • People comfortable making phone calls, writing emails, doing research, and following up — the connective tissue that holds a project in motion.
  • People who believe a nest-shaped treehouse in a community garden on the Lower East Side is a serious act of ecological and community joy, and who want to help build it.
  • Bilingual candidates (Spanish/English especially) are warmly welcomed, given the garden's community and history.

People-Power Fundraising

Community Crowdfunding — Patronicity or ioby
$8,000–$15,000
The treehouse image sells itself. Add a matching grant structure for urgency. The campaign generates press and donor cultivation simultaneously — the campaign is part of the community-building.
"Name a Branch" Micro-Campaign
$10,000 (200 × $50 avg)
Names laser-engraved on Black Locust branch elements. Deeply personal. Impossible to resist for LES families with CMG history. Each name becomes part of the nest.
Annual Garden Gala
$8,000–$15,000 net
Spring fundraising dinner in the garden or with a hotel partner. $75–$150/ticket. Community honoree award for a longtime CMG steward. Celebration and cultivation in one evening.
"Taste for the Trees" Restaurant Week
$5,000 + community visibility
LES restaurants donate $1 per entrée for one week. 10 restaurants × 500 covers = $5,000, a neighborhood story, and press that money can't buy.
"Steward a Tree" — Recurring Giving
$6,000/year sustainable
Monthly givers at $10/month become named Tree Stewards. 50 givers = $6,000/year of sustainable support. Deployable before the permit is finalized — the community builds alongside the structure.
Build Day Live Fundraising
$2,000–$4,000 per build day
QR code giving on-site during the public build days. Press coverage drives online donations in real time. The act of building is the ask — and the joy is the answer.
07 · Pro Bono Architects & Firms

Finding the right creative partner — a task for our summer intern/s

The permit track requires an architect of record. The design track benefits from someone who understands living structures, community process, and the poetry of building with wood that still looks like a tree. The summer intern/s beginning June 24 will lead the outreach to these firms — research, contact, and relationship-building as their first real task.

Paul A. Castrucci Architects (PCA)
Rivington Street, Lower East Side — neighbors to CMG
First call
Mission-aligned firm with 30+ years at the intersection of community activism and NYC DOB permitting. Deep knowledge of the political and spatial landscape of this exact block. The call begins as a neighbor conversation.
May consult pro bono or at a significantly reduced rate for a project this close to home, in every sense.
→ Intern task: draft the initial email for Aresh's review; schedule the call
WXY Architecture + Urban Design
New York City
Participatory design
Leaders in participatory community design and public-space activation in NYC. Strong track record with NYC Parks, CB processes, and community-centered play environments. The community design day process is their native practice.
Demonstrated pro bono practice for high-impact community projects. The CMG story — 43 years, legal victory, LES families — fits their portfolio aspirations.
→ Intern task: identify the right contact person and draft outreach
Future Green Studio
Brooklyn, NY
Landscape urbanism
Leaders in landscape urbanism with a fabrication wing. Specialize in building around living systems and complex ecologies. Could handle both the critical root zone design logic and the Black Locust material palette with real fluency.
Ask about pro bono or reduced-fee practice for community gardens. They understand this kind of challenge from the inside.
→ Intern task: research portfolio and identify relevant project precedents to reference in outreach
SUPERFRONT
Brooklyn, NY
Emerging — pro bono likely
Small, values-driven studio seeking high-visibility civic projects. A permitted nest-shaped treehouse in a beloved LES garden, designed by AreshEarth and advised by Roderick Romero, is a portfolio-defining project for an emerging firm.
Pro bono services are highly likely for the right ask. The visibility and portfolio value may effectively offset the fee entirely.
→ Intern task: draft the outreach framing this as the opportunity it genuinely is
AIA NYC — Pro Bono Referral Program
New York City
Referral network
The AIA NYC chapter connects nonprofits with licensed architects for pro bono service. Submitting a project brief casts the widest net and may surface architects with specific community garden or ecological play structure experience not reachable through direct outreach.
Complement the direct outreach above with an AIA application — different pool, different skill sets, all licensed.
→ Intern task: draft the AIA NYC pro bono project brief; this is the first deliverable

09 · Next Steps

Where we begin — June 24 and forward

Aresh
Call Paul Castrucci (Rivington St) for a neighborly consultation — share the CB3 resolution, the sketch, and the permit question. Ask about the architect-of-record role and the pro bono possibility.
This week
Aresh
Contact attorney Ben Burry to retrieve the arborist contact from the CMG legal case — the court-granted arborist fees established a working relationship that is still the strongest leverage point with both DOB and Parks.
This week
Aresh
Identify and onboard the summer intern/s before June 24. Brief them on the project, the vision, and their first deliverables: the AIA NYC pro bono brief, the 6BC permit research, and outreach email drafts for each firm listed in §07.
Before June 24
Intern/s
Draft the AIA NYC Pro Bono Project Brief — this is the first deliverable. A clear, compelling, one-page description of the Children's Magical Treehouse that any architect would want to be part of.
Week of June 24
Intern/s
Research the 6BC Botanical Garden permit pathway in depth: exact DOB filing type, architect of record, structural classification used, and how the structure was described in the GreenThumb notification. This becomes the template for CMG's filing.
Week of June 24
Intern/s
Draft outreach emails to each pro bono architect listed in §07 — PCA, WXY, Future Green Studio, SUPERFRONT — tailored to each firm's specific interests and portfolio, for Aresh to review and send.
Weeks 1–2
Aresh
Conduct rebar probe soil test at 5–7 proposed helical pile locations. Mark the Mulberry's critical root zone boundary with flagging tape first. Confirm no rubble obstruction within 42" before committing to Techno Metal Post mobilization.
Next site visit at CMG
Aresh
Submit capital funding request to Councilmember Marte's office. Attach CB3 resolution and this portfolio. Frame the treehouse as the joyful, playful next chapter of the La Rosa Stage capital plan already underway at CMG.
Summer 2026
Intern/s
Draft first-round foundation grant letters — Pinkerton, Tiger Baron, Mertz Gilmore — in collaboration with Aresh. Each letter leads with the nest, the Mulberry, and the forty-three years.
Summer 2026
Aresh + Intern/s
Begin LES community partner outreach — Ludlow Hotel, Russ & Daughters, Essex Market — approaching each as a neighborhood partnership, not a sponsorship ask. The treehouse is a story they want to be part of.
Summer 2026
Aresh + CMG
Hold community design day at CMG with LES families, PS 20 students, and neighbors. Let children name the treehouse. Their voices go into every grant application, the DOB public benefit section, and the heart of this project.
