It looks good - but could do with that little bit of extra polish.

Why not continue the timber clad wrap as the balustrading, with progressively larger vertical spacing to the openings/verticals? The boggo railing just looks like an afterthought.

Equally, why not continue the verandah out from the end rooms - at the same level, in a similar materiality. Without a plan it's hard to see why you've gone with the timber deck & step solution - they seem like a late addition, and a lost opportunity.

And plesae, lose the wonk in the window, it looks contrived, and does nothing to talk to the materiality of timber cladding - but do echo/copy it's expressed frame for the door - that'd give the facade composition some continuity and "story".
