Menace Posted January 20, 2005 Share Posted January 20, 2005 Hi folks, slight confusion on the 170 square metre rule. Can someone more knowledgable than I explain! We have a long barn for renovation, total internal floor space 163.8 square metre (ground and attic) measured from the internal wall face. The problem however, is an attach extension some 30m square with its own access. The building do however share a common roof. As stated, access is not possible from the barn. The question is, do I have to include this in the 170 square metre??. By the way, I was hoping to undertake the work myself. Your expertise welcome!.Denis (14) Link to comment Share on other sites More sharing options...
Nick Trollope Posted January 20, 2005 Share Posted January 20, 2005 My interperation of the situation is that if the total surface area of the dwelling (excluding rooms smaller than a certain size/height, garages & the like) is greater than 170m2, then you must use an architect. I don't think that access is an issue. In your case, whilst you can deduct something from your 163.8 m2, for allowable "deductions", you must add the 30m2. BUT, a quick visit to your Mairie would confirm (or otherwise) this. Link to comment Share on other sites More sharing options...
Alcazar Posted January 20, 2005 Share Posted January 20, 2005 I may be mistaken, but I thought the floor area was measured from the OUTSIDE for these sort of things? Certainly, my architect took all measurements from the outside.Also, if your barn is ATTACHED to anything else, another living area, that has to be included in the calculation.Alcazar Link to comment Share on other sites More sharing options...

Yes, this is the downside to the fact that if the barn is attached (and on the same parcel of land on the plan cadastral), then you don't normally need a separate certificat d' urbanisme. paul Link to comment Share on other sites More sharing options...
Menace Posted January 21, 2005 Author Share Posted January 21, 2005 Thanks for all your help. I will obviously have to commission a French registered architect to submit my Permis. No doubt my plans will also have to be redrawn, having spent some considerable time at the drawing board... Well, off to Vire and the surrounding areas in the half term to locate an architect, hopefully one who speaks a little english.Denis. Link to comment Share on other sites More sharing options...

Our architect (87) took the plans as they stood, stuck a couple of French labels on them, although left most of the English, took the photos of before and superimposed after, and completed the 'demande' for us - so you might not have to wait for your plans to be redrawn. Our permis came through in less than a month. Our local mairie thought they might be trying to clear their desks for the Christmas break!Jan Link to comment Share on other sites More sharing options...
Sashabel Posted January 22, 2005 Share Posted January 22, 2005 When we looked into this for our renovation project, we were informed that any room space with a ceiling height of less than 1.8 metres did not come into the 170 sq. m. rule. So if your barn is not a very high one and you are using some of the roof space to convert into bedrooms, you may have some floor space lower than 1.8 metres high - this can be deducted from the total amount.In our case (renovating a traditional longere) the overall floor space would have taken us over the 170 sq. m. ruling, but as the upstairs walls were only 1.5m high, we managed to lose just the right amount square metres to bring it below this figure and all we then needed was the permit.We also submitted our plans showing the room sizes and not the total floor area. With some of the internal walls being nearly a metre thick, we lost quite a few more square metres here as well.Hope this helpsSasha Link to comment Share on other sites More sharing options...
ClaraQ Posted January 22, 2005 Share Posted January 22, 2005 Our French neighbours thought it was hilarious that we were planning to use an architect when we realised our property was over the 170m. ruling. They told us that no-one ever checks the measurements (especially if the location is quite rural and over 15km from the french planning office) and that unless you have a huge property that is obviously over 170 metres you just juggle your figures a bit until they come in at around 165ish.It might have been a nit naughty, but it worked for us and we got our permis de construire by just drawing up our own plans on graph paper. They wanted drawings of the front, back, both sides and how the property stood on the land (i.e. if the land sloped).We also just gave room sizes and not the overall house size just as Sasha said and this also saved us quite a few square metres. The minimum 1.8 metre room height ruling he/she mentions rings a bell as well.Clara Link to comment Share on other sites More sharing options...
Gyn_Paul Posted January 22, 2005 Share Posted January 22, 2005 Is it literally the wall height?When assessing a barn you can't just use the wall height where it then proceeds to sweep upwards to a roof apex, can you ? Surely you've got to average the height across the room. ???paul Link to comment Share on other sites More sharing options...
Sashabel Posted January 22, 2005 Share Posted January 22, 2005 It's any part of the room that has a ceiling height of less than 1.8 metres that is excluded from the 170 square metre ruling. For example, if your total space on the first floor is 90 square metres, but where the roof meets the walls the height is only 1 metre, and your roof only has a shallow pitch to it, then you need to show this on your application. You could have a house with 90 square metres on the ground floor and the same in the grenier, but using this calculation you could well come in under the 170 square metre ruling and not have to employ an architect.Sasha Link to comment Share on other sites More sharing options...

If only I had been tad economical with my measurements this situation would not have risen... does honest really pay!.Denis Link to comment Share on other sites More sharing options...
