ᐅ Floor Plan – What Thickness Should Exterior Walls Be Drawn?

Better make a list of the things that are important to you for each room. This is also called a room schedule.

Then take it to the architect!

Hello, my wife and I are in the process of drawing our floor plan. Should the floor plan only show the outer wall (brick or sand-lime block wall), or the entire exterior wall including the masonry, insulation, brick cladding, etc.?

This is about a floor plan for a house (bungalow). We want to draw the floor plan ourselves and consider as many details as possible.

I hardly dare to ask if you already have a building plot. Don’t be surprised — we have actually met people here who not only didn’t have a plot yet, but it got even more interesting: they wanted a bungalow to save money on stairs. No joke, and it’s not even that rare.

Still, regarding the initial question: first, forget about individual centimeters, because they basically don’t exist in construction — or only on paper. Deviations about the thickness of a thumb in positions and further in squareness and levelness are normal. So never plan anything to exact measurements, because it simply won’t fit. For example, for a cabinet 60cm (24 inches) deep and 240cm (95 inches) wide, you should allow at least 65cm x 250cm (26 x 98 inches) of space, and so on accordingly. Walls can be built in so many different ways that even every contractor has their own preference.
As a general rule, it’s best to think in full tens of centimeters for both wall thicknesses and wall positions when developing your rough draft. Also, as a layperson, you will hardly be able to judge where load-bearing walls should go. So, for practical purposes, just assume 40cm (16 inches) exterior wall thickness and 20cm (8 inches) interior wall thickness.

Closing a thread would be inconsiderate to all readers (and respondents). Otherwise, everyone with the same question would have to ask it again (and it would have to be answered over and over again — which is unmanageable as unpaid work). By the way, your question is a FAQ, but in this case it was just answered faster for the hundredth time here than linking you to where the answer already exists. Even I don’t have all answers memorized for every question.

Thank you for sharing your experience.
Yes, we already have a plot of land.
