Purple Martin

 

 

We struggled with various drafts of this purple martin house design for years and abandoned it as too complicated. We attempted to give it an appearance which unfortunately made the dimensions too complicated. We first made the front walls lean out, which required each floor to have different dimensions with angled cuts. The front of the rooms were wider than the backs so that the roof peaks inclined up from the center to the outside which gave a look we wanted but it created a nightmare of complicated dimensions.

Since beginning again, the side walls were changed to parallel. The roof peaks retained an incline up from the center to the outside which means the top of the walls must also be inclined and the roof can not be made of simple rectangles. Still, it's not as complicated as previously. It's doable and looks nice.

The four front walls still lean out requiring each floor to have different dimensions. The problem with the angled cuts was solved by making a front wall which slides in between sidewalls and attaches at the top and bottom independent of the floor and sidewalls and therefore doesn't need an exact or angled fit.

We really like the easily removed and replaced front wall. Front walls are inserted by tipping the tops inside between the side walls and slipping them up behind facial roof rafters, which raises the bottom of the front wall just above the bottom floor. The bottom of the front wall can then be slid back into the house between the side walls and dropped down into a slot in the floor only enough so that the top remains behind the facial roof joist. Easily removed and easily replaced. And secure. We don't think anything short of extraordinary could lift the front face up and out.

When the front wall is removed, all four rooms in one column are completely open for easy cleaning. There are no hinges, fasteners, and no front lip or protruding edges to hinder scraping dirt off from the room walls, floors or ceiling. Easy access and easy cleaning.

Wind. This design has a rather large profile with it's roof, although maybe not much more, if at all, than some similar 4 sectioned designs, there will be places, windy places that this design is not suited for.

Inserting and Removing the Front Walls

The drawing below shows an inner facial rafter which is attached to the roof. (It is not in the other diagrams. Only the one below.) The front walls are inserted by tipping their tops into the house and slipping them up behind a these facial rafters, which raises the bottom of the front walls just above the bottom floor. The bottom of the front walls can then be slid back into the house between the side walls and dropped down into a slot in the floor just enough so that the top remains behind the facial roof rafter securing the front wall on top and bottom. The front wall is removed by lifting it up until the bottom is free to be removed first until it clears the outside of the bottom floor and the wall then slips down clearing the facial rafter and out.

The slots which the bottom of the front wall rest into are created by the space between a 1x2 bottom balcony floor and the plywood floor (visible above and below). The 1x2 balcony floors are fixed to the side walls

 

 

 

Optional Predator Guards Fitted to Front Walls

Predator Guards Fit into Front Walls
This drawing shows the predator guards, dowels drilled through the front balcony and wall frame. Larger horizontal dowels fit through holes (holes not shown) drilled in the sides of the front wall frame. Vertical dowels fit through holes drilled into balcony floors and horizontal dowels and are fixed to the top horizontal dowel. Dowels are secured into place when the front wall is inserted into place. Fixing with glue or other means is optional.
