Are those pieces part of a set? Or a random build of something?
The 'Red Slope, Curved 4 x 2 with White and Yellow Flames Pattern Model' part (right side of the picture, on the roof) comes in 2 variants: Left and Right. However, both of these parts only exist in the same 1 set, 9441: Kai's Blade Cycle
As such, this model must be a Maker's Own Creation (MOC), and not an official LEGO set. So, yes, a 'random build of something'
Both of the sets listed are from the LEGO Ninjago: Rise of the Snakes series
