Online Architectural Services handled our project end-to-end: 3D concept design, planning permission submission, party wall notices, and full building control packages. Having both architectural design and structural engineering under one roof saved us weeks of coordination. 5/5 stars for technical competence.

We were very impressed with OAS. The team arrived on time for the measured survey, took detailed measurements, and produced exactly what we needed. They were professional, friendly, and easy to deal with. Would definitely use them again.

OAS made the planning permission process much easier than we expected. They handled the drawings and paperwork professionally and kept us informed throughout. Great communication and excellent service from start to finish.

Thanks to OAS, my planning permission was approved smoothly, and I couldn’t have asked for a better experience. I highly recommend OAS to anyone looking for a reliable, efficient, and friendly architectural service. Thank you for making everything so simple!
