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.
