David Geisen: Wild Tree Woodworks


Wild Tree Woodworks specializes in the construction of tree-based structures. Craftsman, designer, and founder David Geisen has been honing his woodworking skills since 2006. After a year spent learning woodworking essentials at the renowned Wood Technology Center in Seattle, David apprenticed with two of the best craftsmen in the Pacific Northwest: first under Treehouse Master Pete Nelson (Nelson Treehouse & Supply, LLC) and then under master builder Jon Romanelli (Timbers & Tilth, LLC). David founded Wild Tree Woodworks in 2013, continuing the tradition of crafting fine spaces while honoring the trees from which we receive our most sublime building material.

Our Process

To get your project off the ground and into the trees, your first step is to reach out to us. After an initial telephone conversation or email correspondence, David will schedule an On-Site Consultation.


On-Site Consultation

If you have dreams of a treehouse, we are here to help make those dreams come true.

David will come to your property and hear all of your thoughts and answer all of your questions. These may include envisioned uses, space requirements, design visions, financial parameters, desired materials, scheduling thoughts, or permitting issues.

Together you will make a site survey, walking your land and discussing potential build locations, evaluating trees, and helping to choose the best location for your treehouse. Once determined, David will visually assess the health of the chosen trees and make detailed measurements of the trees and the site.

Using these measurements, along with the knowledge of your ideas and dreams, David will make concept drawings of your future treehouse. From these drawings (plan view & elevation view) you will work together to refine the overall design.

For locations in the Pacific Northwest, we charge a flat fee of $1,000 for the On-Site Consultation and concept drawings.

If during the consultation you decide to pause and not move forward, we reduce our fee to $500 to account for the consultation without drawings.


Design & Budgeting

Design is an engaging part of our process. David works with you and develops complete plans for your new treehouse, detailing materials to be used and options to be included.

Our design process moves forward hand-in-hand with budgeting. At the end of this phase, we provide a detailed cost estimate for the building of your treehouse. This estimate will be refined and serve as our contract.

If David recommends the hiring of an arborist to evaluate your trees, this will happen at the beginning of Phase 2. The more being invested in the structure, the more important it is that your “foundation” be given the thumbs-up from a certified consulting arborist.

Based on the projected cost of your project, a deposit will be requested at the end of Phase 2. This deposit will add you to our build calendar.PHASE 3

Engineering & Permitting (if needed)

Depending on the size, location, and budget of your treehouse, building permits or an engineer’s approval may be recommended or required. Engineering and permitting will extend the pre-build calendar. As with any building project, it is best to start the planning process early.


Scheduling & Contract

Based on our calendar and yours, we will determine a start date for the building of your treehouse.

At the beginning of Phase 4, we will agree on a contract that details the design, construction, pricing, and payment schedule for your treehouse. A start date will be set and we will ask for a down payment, usually between 25 and 50% of the cost of the treehouse. This down payment covers the ordering & delivery of materials, initial payroll, on-site insurance, travel, and any refinements to the final design.

The remaining cost of your treehouse is broken into two payments, the final being due upon completion of the build. This schedule is detailed and agreed to in the contract.

Once on-site, we will build your treehouse in 2 to 6 weeks.
