Quick summary

To prevent your dormer from becoming an eyesore, focus on good design and quality. Choose styles that match your home’s character, like cottage windows, and ensure your extension is well-insulated to save on energy bills. Keep the structure neat and in proportion, and consider using permitted development rights if your council allows, to avoid extra hassle and costs.

When it comes to adding both new space and value to your home, no project does it better than the loft conversion. However, finding the headroom and space to make this happen can be a challenge for a lot of UK homes.

For this reason, you might be considering a dormer, which is a box-shaped structure that is added onto a pitched roof, creating walls that sit at a 90-degree angle to the floor. This addition is fantastic for adding new space, but many homeowners worry about their dormer becoming an eyesore. No one wants an ugly box stuck to the top of their roof!

To stop your conversion from becoming the ugly duckling of the street, here are some tips on creating a design that is both practical and attractive.
