12 Things I Wish I Knew Before Building a House

What happens here

Due to the absence of traditional vertical walls and attic space in an A-frame, 'half walls' or knee walls are necessary to create cavities for running essential utilities such as HVAC ductwork, electrical wiring, and plumbing pipes. These half walls, while serving a functional purpose, consume square footage that might otherwise be usable. It's important to understand that large ductwork for HVAC and various vent pipes (like for bathrooms or dryers) will occupy this space, making it unsuitable for built-in storage or shelving, as originally envisioned by some owners. Running ductwork through a crawl space (if available) can also lead to inefficiencies.

Goal: Account for half walls to house HVAC, electrical, and plumbing.

Tools and materials

  • Electrical Wiring
  • HVAC Ductwork
  • Lumber for Half Walls
  • Plumbing Pipes
  • Vent Pipes

What they say

traditional wall on the side number two on the list is this little half wall that's being put in place again you're losing all that square footage and the reason they have to put this wall in certain rooms like the bedroom or the upstairs that I'll show you is because you have to be able to have places to run run your HVAC and your plumbing in order to actually fit it you could possibly run it through your crawl space but the problem that that some things like HVAC specifically all the duct work becomes very inefficient when it's being run underneath the ground especially if the furnace is right here some of the things can run through the walls but some things have to run through the pony wall like this HVAC duck work that's pushing out all the vents outside and vents like your bathroom vent or even your dryer vent and even your HVAC vent pipes on the upstairs Loft some of the DCT work is a lot larger as you can see this is blowing the hot or cold air inside of it so when before the hbag goes in you might consider oh maybe I'll use this as storage or maybe built-in shelves or built-in closet space but you really can't this is all meant for all that stuff to be running through and yeah it continues on the other side it's all loaded with basically all the HVAC electrical and plumbing number three on
