Planning For Loft Conversion – Have You Thought About Ventilation

Planning for loft conversion? If you are, it can be tempting to think, how hard can it possibly be? After all, you are only planning another room in a pre-existing space in your house! However, planning loft conversions isn’t as simple as you may think, and one of the many things you need to consider in your plans is ventilation.

Properly ventilating a space in any part of your house is important for a number of reasons, most importantly, of course, is allowing you to breathe. However, as crucial as this is, it is not the only reason why loft conversion plans need to include planning for adequate ventilation. There is also the problem of condensation. Left unchecked, condensation can cause damp and all the problems that come with this, including the growth of mould spores that are dangerous to health and cause problems throughout the building’s structure. Architectural house extension plans for your loft extension will need to include both rapid and background ventilation. Rapid ventilation is achieved through the inclusion of windows that can be opened as required. Background ventilation responses may differ depending on the size, construction, and purpose of the extension. If the loft is to be used as a bathroom, you may need to include mechanical ventilation that can extract 15 litres of air per second. Ventilation in the roof void, as well as at the eaves and ridge levels, may also be necessary. The best way to ensure you have the right ventilation plans for your conversion or extension is to have the floor plans drawn up by a professional architect.
