Services

What we build, repair, and dream up.

Every treehouse is one-of-one — designed around your trees, your kids, and the way your family already plays in the backyard.

Open-air treehouses & tree forts

Platforms, railings, roofs, and clever nooks designed for fresh air, sightlines, and pure imagination. The classic backyard hideout, done right.

Enclosed, weathertight hideaways

Insulated walls, real windows, sturdy doors, proper roofing. A four-season clubhouse — for sleepovers, reading forts, and the occasional adult escape.

Ziplines & climbing features

Ziplines, climbing walls, rope bridges, cargo nets, fire poles, slides — engineered with proper hardware, tensioning, and landing zones.

Repairs & safety inspections

Annual once-overs, hardware checks, zipline tension and brake adjustments, decking and railing refresh. Older treehouse from another builder? We can take a look.

Decks, stairs & railings

Ground-level decks, elevated landings, switchback stairs, and code-minded railings — built to match the look and longevity of the treehouse above.

Siding & finish options

Cedar shingle, board-and-batten, live-edge accents, stained pine, painted clapboard. We help you pick a finish that ages well in the New England weather.

Cost guide

What does a custom treehouse actually cost?

The honest answer: it depends on the tree, the dream, and the details. A simple open-air platform with a railing and a ladder is one budget. A two-room, weathertight hideaway with a zipline, climbing wall, and cedar siding is a very different one.

These are general planning ranges so you can decide what level of project fits your family. Final pricing comes after Tony reviews the tree, access, height, materials, safety hardware, features, and any town or permit requirements.

Get a better first number

Send the right photos and Tony can price it faster.

The best first estimate starts with a few simple details. You do not need perfect measurements, but photos and a rough wish list help Tony tell you whether the project is closer to an open-air 8x8, a weathertight hideaway, or a bigger adventure build.

Take 4 backyard photos

Stand back far enough to show the whole tree, the ground around it, nearby fences, slopes, sheds, pools, and where kids would enter the treehouse.

Share your town and access

Tell Tony where the project is, whether materials can reach the backyard easily, and if there are tight gates, steep slopes, or long carries.

Pick a starting style

Open-air 8x8 builds start at $17,000+. Weathertight 8x8 builds start at $21,000+. Bigger builds, bridges, ziplines, and finished interiors raise the scope.

List the fun features

Rock wall, bucket pulley, monkey bars, bridge, slide, loft net, windows, siding, and finished interiors can be added to the plan once the base structure is right.

Process

From first phone call to first climb.

A good treehouse starts with a strong tree — then permits, materials, and schematics. Here’s how we get from your backyard to your kid’s favorite place on earth.

01
Talk

A quick call. Who’s climbing, what they’re dreaming up, what your backyard looks like, and what budget feels right.
02
Site & tree review

Tony comes out, walks the yard, checks the tree’s species and structure, and talks through layout, access, and any permits.
03
Design & proposal

A written design with materials, features, hardware, and a clear price. No surprise add-ons later.
04
Build & walkthrough

We build on-site, keep the yard tidy, and finish with a hands-on walkthrough so kids and parents know exactly how to use everything safely.

Past projects

A few of the builds we’ve loved.

Every backyard is different. These illustrated examples show the kind of range we work across — from a simple platform to a full backyard adventure.

Open-air platform with flag mast

Classic single-tree fort — sturdy platform, kid-height railings, and a wide ladder up the back.

Cedar siding, gabled roof, a true door, and big windows — built to stay warm and dry in a New England winter.

Zipline-ready platform

Launch deck with backyard zipline

Engineered cable run with tensioner, brake block, and a soft landing — set up for hours of laps.

Live edge siding detail

Hand-selected cedar siding

Live-edge boards and warm stain — the kind of finish that gets better with weather, not worse.

Multi-tree build

Two platforms, one rope bridge

Connected hideouts spanning two trees — a bridge to cross, a second deck for the older kids.

Full backyard adventure

Climbing wall & slide combo

Cabin, climbing wall, and a real slide — the kind of build that turns into the neighborhood headquarters.

Safety & repairs

Built to last. Inspected to stay that way.

Treehouses live outside in New England weather. Even a great build benefits from a yearly walk-through to catch hardware fatigue, decking wear, or a tree that has grown into something new.

We service treehouses we built and treehouses we didn’t. If you have an older structure and you’re not sure it’s safe, we’ll come look.

Schedule an inspection

Annual safety inspectionTop-to-bottom check before the kids climb back up in spring.
Zipline tension & brake adjustmentsSag, cable wear, trolley condition, brake bumper, landing zone.
Hardware upgradesTreehouse attachment bolts, lag screws, brackets, fasteners.
Rot, decking & railing repairReplace soft boards, tighten railings, re-stain weathered finishes.
Seasonal maintenanceOpen it up in spring, button it up before winter.

Kind words

— Kara Lafferty

“I believe that Tony Pola is still accepting commissions for Cape Cod Treehouses: a great retreat for either parents or kids.”

FAQ

Questions families ask before they call.

Do I need a permit for a backyard treehouse?

Sometimes. It depends on your town, the size and height of the structure, and how it’s attached. Once we walk your yard, Tony can tell you what your specific town in Massachusetts is likely to require — and help you handle it.

What kinds of trees work best?

Strong, mature hardwoods like oak, maple, and beech are favorites. Cape Cod pines can work for the right design. The honest answer is that the tree comes first — we’ll look at species, health, branch structure, and lean before we promise anything.

How much does a custom treehouse cost?

An 8x8 open-air treehouse starts at $17,000+. An 8x8 weathertight treehouse starts at $21,000+. Bigger decks, bridges, ziplines, climbing walls, finished interiors, height, and difficult access can increase the price. We’ll give you a written proposal with no surprise add-ons after we see the site.

Can adults use the treehouse too?

Yes. We build to hold adults, which means kids are very, very safe. Plenty of our clients confess that the treehouse becomes a quiet reading spot for the grown-ups too.

Do you repair existing treehouses, even ones you didn’t build?

Yes. We inspect, repair, and upgrade treehouses we didn’t build all the time. If you have an older structure and you’re unsure it’s still safe, we’ll come take a look.
