Using mixture of trusses and rafters?

[murty3000]

Hello,

I'm making a 2-storey 8' x 6' playhouse in 5x2 timber. I've completed the 'downstairs' framing and sheathing and am now trying to design the top floor.

I intend to make the roof as steeply pitched as possible for aesthetics.. around (50 degrees). The roof will be covered in box profile metal sheet.

My thought was to build a sturdy truss for each end gable and 3 or 4 rafters in between supporting a ridge beam (to facilitate a 50cm overhang).

Q1. Does steep roof pitch affect this idea?
Q2. Is it permissible/advisable to use a mix of truss and rafter on a roof design?
Q3. How best to attach/support the ridge beam?

I've struggled to find anything online that discusses ridge beams at any length so any links gratefully received!

Many thanks.

The first picture is the original inspiration.

The second picture is a my (modified) attempt.

Wildly ambitious for a first project but I'm going for it nonetheless.

Notch the end trusses to support the ridge beam. Cover the end grain of the ridge with fascia boards.
50 degrees is fine - my house is 49 degrees

Thank you Myfordman.
