Mubbashshir Posted January 26 Posted January 26 We are doing a garage conversion and planning to replace the Garage door with an attached French door(also attached is the front elevation of our house with the existing garage door in black). Now the current challenge is after raising the floor, we are left with 2050 mm height, and if we allocate 75mm to the French door frame on top and the remaining 55mm at the bottom for the Sill, we are left with 1920 clear space for the French Door, but standard clearance is 2000 mm. Can we talk to Building Control for any exceptions my Building Control inspector advised me to jack the lintel above the garage door and remove some bricks, which I have explained I am not very comfortable with as it carries bricks and the roof at the top& its old structure. What is the minimum height acceptable? If we have to meet a minimum height of 2000 mm any suggestions? Can we not keep the floor a little bit lower where the door is opened or closed to meet the building regulations or can we ask for an exception as we don't want to jack the lintel and risk any structural integrity of the building Also, can we do something about U-value, as the Building inspector warned me about draft from a wide French Door?
Russell griffiths Posted January 27 Posted January 27 If you want a better u value then you need to buy a better quality door, if you want more height then get a door with a disabled access threshold so it’s only 15mm high. you will still need 2100 high roughly from floor to underside of lintel. why French doors, they will look strange at the front, are not very secure and tend to drop if you buy cheap ones. window and a good quality solid core door would be my choice. 1

As Conor says the opening “may” not work - you’ll need restraint to the front wall and bearing for the lintels. If you add heating you will need to insulate the walls, floor and roof. If you insulate the roof you will need to ventilate the roof. If you don’t access the new space from a hall you’ll need an EEW. If you create a new living room you’ll need a smoke alarm within 7.5m - interlinked with any detection in the house. And so on and so forth.

Building inspector is asking to keep the garage door and do the conversion behind it. Any suggested how to ensure it looks good, I am alright to have some storage space however would like the space behind the garage door and and actual conversion wall to be fully insulated and tiles so it has good ambiance. Also we should think of ventilation from front. Altough plan is to put a extractor fan in the front.

Any suggested how to ensure it looks good Good? Well, it depends on your view. Like a garage door? Yes, we can do that. So as not to lose too much space the logical idea is just to leave the up-and-over (I assume) door 'for show'. If it is to open you will need a store-room equal in depth to the part of the door which projects in to the garage. I would build a timber stud wall which is finished externally as if it were 'proper external', including excellent air-tightness - and on the internal side well insulated (with a VCL too) of course. Where will your extractor fan to the front go? Might I suggest a trickle vent above the garage door (and a corresponding vent in the stud wall and have the fan (which does not look particularly pretty) at the rear?
