Sunken fire pit with seating

Merbau panels built for seating on concrete blocks around a garden fire pit set on a white pebble setting. 



The project


My partner and I built a beautiful sunken fire pit or conversation pit using decking boards, concrete blocks and white pebbles. It’s perfect for roasting marshmallows on cold winter nights, or for relaxing with friends on a sunny afternoon.




Step 1


The first step was to measure out the size and depth we wanted the fire pit and dig the hole. We also had to remove an old brick path and a clothesline.




Step 2


We next dug a trench and filled it with cement to secure the concrete blocks.




Step 3


Then we added two rows of heavy concrete blocks for the base. 



Step 4


Creating the frame using lengths of timber was a matter of trial and error in deciding exactly what we were looking for in a bench seat.



Step 5


We finished the back of the seat and starting adding the decking boards. We used the same Merbau decking boards for the deck we built earlier in the year. 




Step 6


We finished the decking boards and added some strips along the concrete blocks to complete the look.



Step 7


Once the seating was finished we added some final touches including painting the concrete blocks white, putting a weed mat on the dirt and adding white pebbles. We only put a weed mat at the bottom to allow drainage instead of black plastic. We live in Perth, so it’s only sand under that, which means the water drains straight through.  



Step 8


Later on we added festoon lights, and now we love hanging out in our backyard; summer, winter, night or day, the fire pit is the perfect place to hang out.



If anyone else wanted to tackle this project, I would say go for it. It really wasn’t too difficult. The hardest part was trying to figure out measurements for the angled back rest. Unfortunately, I don’t have any official measurements written down because we were really just making it up as we went along.


Our dog Billie loves to have a sunbathe on it, too.
