My house was built in 1999. It is not in a conservation area.

✅ 1. Side Door into Garage (Gable End) Likely permitted development if: Your garage is part of your property and not a listed building. You're not in a conservation area or Article 4 direction zone. The door doesn’t face a highway (i.e., a main road). > Note: You may still need building regulations approval for the structural opening and fire safety. ✅ 2. Wooden Fence on Parking Space Permitted development if: It's under 1 metre high when adjacent to a highway (road or footpath). It's under 2 metres high elsewhere. It’s not blocking visibility for vehicles entering/exiting (important for safety). > If your neighbours have done it, this is a good sign — but they might have had different circumstances (e.g., no road nearby). --- ✅ 3. Skylight in Garage Roof Skylights are permitted under the following conditions: They don’t project more than 150mm above the roof plane. They are below the highest part of the roof. Frosted glazing and 1.7m sill height if overlooking neighbours (to avoid privacy issues). For garages, this usually qualifies, but if the garage is detached, or converted to a habitable room, other rules may apply
