The steps to a Nelson Treehouse built structure:
The Site Visit or Consultation
We meet your trees, discuss your vision, take measurements and get everything we need to design the treehouse of your dreams.
Design and Budget
The information that we gathered during our site visit is now transformed into drawings of your unique treehouse. A plan is developed: we figure out the nuts and bolts of the structure and work with you on material specifications. We create an estimate based off of the specified budget.
Signing a contract to build a treehouse! Schedule construction.
Every treehouse built by Nelson Treehouse and Supply is custom designed for the unique tree scenario, client's design aesthetic and the location in which we are building. Factors like:
- Height of the treehouse off the ground
- Access to the project area
- Time of year (i.e. peak travel season costs, weather, etc.)
- How many trees you wish to connect to
- Materials used
- Logistical costs (e.g. accommodations, plane tickets, car rentals, etc.)
Therefore, average starting cost of a 200 square foot custom NT&S built treehouse without plumbing in Washington State is $150,000.00.
The average starting cost of a 200 square foot custom NT&S built treehouse without plumbing out-of-state is $180,000.
The custom design fee of $15,000, interior furnishings and any permitting or engineering fees are in addition to the cost of the treehouse construction price.
*Please note that if you want amenities like water and/or electricity in your treehouse, it is the homeowner's responsibility to permit and install the necessary infrastructure (e.g. septic system) that can be accessed by the future treehouse - these costs are above and beyond the costs outlined above. Adding plumbing to a treehouse is a large expense so we recommend considering more economical and environmentally friendly options like compostable toilets and grey water sinks.
**It should also be noted that treehouse permitting and/or engineering will be required in most cases - this process can add upwards of $20,000 to the cost. We recommend researching what your local building authorities and any Home Owners Associations will require for a treehouse build as it varies from place to place.
A permitted and engineered treehouse built out-of-state with plumbing will have a base cost of approximately $225,000.00. Keep in mind that this is a custom built, expertly crafted house (suspended in a tree). We pride ourselves on providing our clients with not only the highest quality product, but also a fulfilling experience that results in their dream treehouse becoming a reality.
