For an entrance hallway that's starved of natural light, it makes sense to opt for a glazed or partially glazed front door. If you're concerned about privacy, you don't have to use clear glass, you could go for patterned, frosted, coloured or tinted designs to blur the view. To ensure that the door remains secure, it's advisable to install toughened glass.
If professional glazing is beyond budget, why not fake it with coloured window film? You'd never guess this colourful stained glass window film from Purlfrost isn't the real thing, plus it is a fraction of the price and can be removed easily.
