livingthedream Posted June 21, 2022 Share Posted June 21, 2022 Hi, In the process of converting a car port into an annex. Have attached a pic, but if i'm looking to install a window based on the image attached, how do I determine which lintel to use, it's single storey, window width roughly 1100mm Do i need to get a proper calculation done etc, or just install a large enough concrete lintel above Link to comment Share on other sites More sharing options...
Marvin Posted June 21, 2022 Share Posted June 21, 2022 Well this is delicate.... When I altered our garage to habitable space I checked with the building inspector. Link to comment Share on other sites More sharing options...
Temp Posted June 21, 2022 Share Posted June 21, 2022 (edited) Ideally you should get proper calculations done. But you only have one block above the window and you're probably going to be removing it to get the lintel in. So I'd replace that block with a lintel and a course of bricks. Propose a lintel depth that avoids cutting bricks or extra thick mortar. See if BC ask for calculations. The length of the lintel should be at least 300mm (2×150mm) longer than the opening. Round it up to next available length or perhaps the nearest whole or half block. Whatever is easier/available.
