In this case, steel security bars were placed in front of the windows to allow them to open maximum 4". **Q: What are the specs on the garden shed?** *(in Photo Questions)* My husband and i are in the process of a major landscape project. We live in a 1909 prairie-style home. We love the look of this garden shed and feel that it would look lovely in our garden. Would greatly appreciate your response. A: The cabana is 6'10" wide x 12'3". The siding is rough sawn cedar stained to match the tree trunks on the property. The base is Indiana limestone. **Q: Wall feature** *(in Photo Questions)* Is the wall made out of wood? A: The stacked block wall at the back and archway in the foreground are made from rift cut white oak. The wood was bleached, lightly stained and sealed. The side walls are veneer bricks. Each brick was cut on site and glued to the wall to imitate an actual brick wall without losing space in the stairwell. **Q: love the narrowness. what were the dimensions?** *(in Photo Questions)* A: The overall lot is 50'x135'. The pool is 10'x24'. **Q: The patio door…would you be kind and let me know who manufactures.** *(in Photo Questions)* A: All the metal frame doors and windows were manufactured by Hope's Windows in Jamestown, NY. **Q: The semi Patio wood shades** *(in Photo Questions)* for what purpose were they made? and who makes them in Toronto area? thanks A: We built them ourselves. --- *Source: Houzz professional profile.
