Rustic Garden Storage Shed Build

I want to build a wooden shed as a dedicated place to store all my garden tools and equipment. I'll want blueprints based on my measurements, suggested material list that will stand up to weather, a solid frame off the existing garage block wall, adding cladding and roofing that tie in cleanly, hanging secure double doors, and finishing the inside with fixed shelving units and sturdy tool racks so everything has its place.

Because the shed’s purpose is purely storage, function and longevity matter most. I need proper flashing where it meets the garage, pressure-treated timber or an equivalent weather-resistant option. Leave the exterior in a natural stain that matches the garage trim; no bright paints.

Please see the attached outline and photos showing ideas exterior and doors.
