If the house doesn’t have a basement, but has a foundation, you can cut through the foundation and dig out a new ‘basement’ for your lab. This is where the engineering knowledge comes in handy. Depending on local laws, this is also likely to be illegal without permits, and very very difficult to get approved for a permit. See How to Dig Out a Basement in an Existing House. {“smallUrl”:“https://www. wikihow. com/images/thumb/e/eb/Build-a-Secret-Laboratory-Step-2Bullet1. jpg/v4-460px-Build-a-Secret-Laboratory-Step-2Bullet1. jpg”,“bigUrl”:"/images/thumb/e/eb/Build-a-Secret-Laboratory-Step-2Bullet1. jpg/aid100307-v4-728px-Build-a-Secret-Laboratory-Step-2Bullet1. jpg",“smallWidth”:460,“smallHeight”:345,“bigWidth”:728,“bigHeight”:546,“licensing”:"<div class="mw-parser-output">

Digging out the crawlspace to a decent height for walking around in is the method here. {“smallUrl”:“https://www. wikihow. com/images/thumb/8/80/Build-a-Secret-Laboratory-Step-2Bullet2. jpg/v4-460px-Build-a-Secret-Laboratory-Step-2Bullet2. jpg”,“bigUrl”:"/images/thumb/8/80/Build-a-Secret-Laboratory-Step-2Bullet2. jpg/aid100307-v4-728px-Build-a-Secret-Laboratory-Step-2Bullet2. jpg",“smallWidth”:460,“smallHeight”:345,“bigWidth”:728,“bigHeight”:546,“licensing”:"<div class="mw-parser-output">

Also study older construction techniques that have held up over the ages. If you have the time and supplies (and strength) you could build a rebar-reinforced granite wall by drilling through large granite blocks and connecting them with rebar through the holes, then seal with concrete. This combination of old and new will yield a strong wall that has a classical dungeon look to it. {“smallUrl”:“https://www. wikihow. com/images/thumb/b/bd/Build-a-Secret-Laboratory-Step-4Bullet1. jpg/v4-460px-Build-a-Secret-Laboratory-Step-4Bullet1. jpg”,“bigUrl”:"/images/thumb/b/bd/Build-a-Secret-Laboratory-Step-4Bullet1. jpg/aid100307-v4-728px-Build-a-Secret-Laboratory-Step-4Bullet1. jpg",“smallWidth”:460,“smallHeight”:345,“bigWidth”:728,“bigHeight”:546,“licensing”:"<div class="mw-parser-output">
