Fixed Price Planning, Building Control & Architectural 
Drawings in Durham & North East England

Fixed Price Construction Drawing Packs

At KPLan, we believe getting professional construction drawings should be straightforward, transparent and affordable. Our fixed-price drawing packs are designed to make it easy to understand exactly what is included before you commit, with options available for planning drawings, building control drawings, or a complete planning and building control package. Whether you’re planning an extension, conversion, renovation or new build, choose the package that best suits your project and get professionally prepared drawings without the uncertainty of complicated pricing. Please note that our prices are for construction drawings, and processes such as planning permission applications and building control inspections, amongst others, do incur their own fees. We have a guide at the bottom of this page to help you identify which authority/agency costs may apply to your specific project.
