Quick summary

Choosing the right door depends on your space, budget, and style. French doors are classic but may cost more and suit traditional homes. Sliding doors are space-efficient and good for large openings, typically costing more for bigger panes. Bi-fold doors are popular but expensive and take up space when open. Consider your home's size and look to pick the best fit.

Think doors are boring? Think again! If you’re undertaking a rear, side, or wraparound extension, doors can transform your entire household. Far more than just a simple gateway to the outside, the options on offer allow you to bring more light into your home, as well as creating a real WOW factor for future buyers.

French doors

Starting with the most traditional option, french doors bring a classic touch to any home.

French doors are mainly categorised by opening on a hinge, rather than a sliding mechanism like patio doors. This gives a traditionalist touch, which can enhance the charm of period properties, or add character to new builds.

If you’re looking for more natural light into your home, but want to avoid extensive panes of glass for privacy reasons, then french doors would make an excellent choice.
