Pond Filter House

I have a goldfish pond in the back yard, and built a wooden structure to house the electrical, air pump, light timers and filter. After a few years the wooden structure was deteriorating and looked not-so-good. So, build a new one out of stone. Concrete blocks actually. Started with a level base of concrete 12" x 12" stepping stones, and started stacking the tumbled Belgian wall blocks from Menards. The wall blocks were given a dab of Liquid Nails construction adhesive in lieu of mortar. Where I had to cut the blocks for the doorway I used a 10" brick saw from Harbor Freight Tools.

After stacking the bricks to the desired height, I used Liquid Nails and concrete screws to attach wood 2x3's to the top and constructed a wooden frame for the roof. Then cedar shingles and a soldered copper cap to top it off. I made the rear roof section removable to have easy access to the electrical and timers, also put in a shelf to store misc pond supplies.

The front door is constructed from cedar planks and is the access to remove the filter for cleaning / servicing.

What I learned and would do differently next time: While the 12" x 12" base stones have been stable for several seasons and the filter house has not budged or settled, I would pour a small concrete slab if I was to do it again. I plan to build a tracked shelf for the filter that is on sliders - pulling the filter out the door sideways when full of water is not really a fun task.

    Oh my, I love it!!

    Did you happen to snap any photos of the process while building this? If you did, you could add them which would be really fun to see. If not, remember to snap some process photos on your next project! ; )

    Thanks! My Sweetie is looking on her phone to see if she saved any of the in-progress pics. Hopefully she can find a few.
