Many clients ask if they need planning permission for a garden office. While some projects fall under Permitted Development, we assess your specific site in Lewes to advise on the necessary path. Another frequent question involves thermal performance; we use high-grade insulation to ensure your building remains comfortable in winter and summer. Finally, clients often wonder about timescales.
