How to build a raised play fort
Project history: I designed and first built this raised play fort in 2004.
I released the plans and instructions for the fort as a 'buy plan' in downloadable format that same year.
In July 2005 there was a free version released in the BuildEazy website. Since then there has always been a free online version as well as a $5 downloadable ad-free version.

How to build a Kid's raised Play Fort - A fort that will provide hours of fun for kids young and old!
This detailed plan-set with step-by-step instructions is in both metric (mm) and imperial (inch) dimensions.
The design includes a trap door entry, a climbing wall, a swing, and there is an allowance for a slide.
The complete frame is fixed together with bolts, so as well as being very strong, the fort can also be dismantled.
The footprint (ground area) is Approx 1800mm x 1800mm (6' x 6'), and the overall height is 3200mm (10' 8").
Floor area is 1500mm x 1600mm (5' x 5' 4"), and the floor height is 1300mm (4' 4").
About the wood sizes
The dimensions of the lumber used for this project are given in both metric and inches. All dimensions are first written in millimeters followed by feet and/or inches encased in brackets.
Note: Metric Vs standard - measurement variations:
The metric (mm) measurements given in this project are not an exact match to their equivalent imperial (inch) counterparts.
That's because the actual size of lumber in North America is different to that in Australasia.
The imperial (inch) measurements are suited to North America and the metric (mm) measurements are suited to Australasia.
So use one system or the other but do not mix and match.
Frame lumber sizes (widths and thicknesses) referred to in this project are the approximate actual sizes, that is, the size of the lumber once it has been
surfaced (dressed, planed). The actual size is smaller than the nominal size.
For example, if you pop along to the local lumber store and ask for a length of 100mm x 50mm (2x4) lumber that has been surfaced, dressed, or is dimensional, the actual finished size will be approximately 90mm x 45mm (1 1/2" x 3 1/2").
Note: The actual size of lumber (with the same nominal size) in North America differs to that in Australasia.
The table below shows the approximate differences between the nominal and actual sizes of framing lumber. Alternative sizes are mentioned on the next page.
|Metric (mm) Australasia|
|NOMINAL SIZE||ACTUAL SIZE|
|50mm x 50mm||45mm x 45mm|
|75mm x 50mm||70mm x 45mm|
|100mm x 50mm||90mm x 45mm|
|150mm x 50mm||140mm x 45mm|
|100mm x 100mm||90mm x 90mm|
|Standard (inches) North America|
|NOMINAL SIZE||ACTUAL SIZE|
|2" x 2"||1 1/2" x 1 1/2"|
|2" x 3"||1 1/2" x 2 1/2"|
|2" x 4"||1 1/2" x 3 1/2"|
|2" x 6"||1 1/2" x 5 1/2"|
|4" x 4"||3 1/2" x 3 1/2"|
