Morning, my wife and I are in the process of drawing our floor plan. Does the floor plan only consider the outer wall (brick/calcium silicate stone wall) or the entire outer wall including masonry, insulation, clinker, etc.?
This is about a floor plan for a house (bungalow). We want to draw the floor plan ourselves and pay attention to as many details as possible.
I hardly dare to ask if you even have a plot yet. Don’t be surprised – we’ve encountered people here who not only didn’t have a plot yet, but then the joke went further: it was supposed to be a bungalow to save money on a staircase. Seriously, and not even rarely.
Nevertheless, regarding the initial question: first forget about single centimeters, they don’t exist in construction anyway, or only in the plan. Thumb-thick deviations in positions, and more in squareness and flatness, are the norm. So under no circumstances plan anything exactly to measure, because then it won’t fit. For a cabinet 60 cm deep and 240 cm wide, allow at least 0.65 x 2.50 m of space (and similarly so on). Walls can be built in so many different ways that every contractor prefers a different one.
Generally, it’s best for you to think in full ten centimeters both for the thicknesses and the positions of the walls if you want to develop the preliminary draft yourself. Also, as laypersons, you will hardly be able to judge where load-bearing walls belong. So practically, just assume 40 cm exterior wall thickness and 20 cm interior wall thickness.
My question was answered by @andimann. Thread can be closed.
Closing a thread would be antisocial towards all readers (and responders). Otherwise, everyone who has the same question would have to ask it again (and it would have to be answered countless times – which is impossible without pay). By the way, your question is a FAQ, but in this case it was simply answered to you faster the hundredth time than linking you here where the answer already exists. I myself don’t have all answers memorized for every question.
