Listed Buildings & Conservation Areas in Midlothian
Midlothian has 21 designated conservation areas, covering historic locations including Dalkeith, Eskbank & Ironmills, Lasswade & Kevock, Penicuik, Roslin, Gorebridge and Newtongrange.
If your property is listed or located within a conservation area, replacing your windows can involve additional planning considerations.
The design, materials, proportions and appearance of replacement windows can all be important when maintaining the character of a traditional building.
We understand that navigating the process can be daunting, which is why we work closely with a local architect who can provide guidance and assist with the relevant drawings, documentation and Listed Building Consent process where required.
Our aim is to make the process as seamless as possible while ensuring your new windows are appropriate for the property.
