Just drew this up for the consideration of my grandson (nearly 2) and his mum and dad. Look about right for the woods at the bottom of the garden? Interior simple with wooden table and chairs, and a little mattress for naps (well he must sleep sometimes?!) Insulated. flywire on window for summer. door glazed or lower half half paneled.Brass doorknob in the exact middle, of course, but with a latch to the left.
Also for anyone out there who wants real Middle Earth architecture for their child’s first home away from home. Tree carvings and brickwork can be done to your taste – all in ferrocement. Colours from stained iron oxide (the rusty brown) to painted any colour the Gaffer approves… email me, etc firstname.lastname@example.org .
