I designed a pergola for the new deck we were having built. I used a 3D program, AC3D, that works like Lightwave, but is much simpler at a fraction of the cost.
This house came with a crazy 3-part deck, no part of which was really large enough to be useful. A demo and rebuild of the deck also includes adding a beautiful pergola.
A porch floor that was rotting provides opportunity for a few additional improvements in this lovely old covered porch.
