What Our Clients Say
I’ve had the pleasure of working with Seema, who created and executed some incredible ideas for our floor plan reconfiguration and kitchen addition. She is a productive and considerate person who has fulfilled her commitments to produce everything on schedule. Seema, I appreciate all of your support. Online Architecture Services is a very skilled and knowledgeable company.
The level of communication, consideration, and knowledge we received from Online Architectural Services really impressed us. The group was amiable, dependable, and competent. They collaborated closely with us, assisting us with the planning and design phases as well as the hiring of structural engineers, quantity surveyors, party wall surveyors, and quantity surveyors, and preparing us for what will hopefully be a successful build.
We are very pleased with the service provided by Online Architectural Services. The procedure was clear at every step of the way. Nothing was too difficult, and we felt in command of our project. As a result, we thoroughly enjoyed the process and are enthusiastic about our project!
Just starting out with Online Architectural Services, and I’m already very impressed with their professionalism and services. We are excited to collaborate with them on our project because so far it has been a real pleasure! In addition, their price is very fair, especially in light of the potential contribution they can make to our project.
Online architecture services provide excellent service throughout and are very professional. They are the best providers of planning permission, so I am delighted and highly recommend them.
Fantastic service from start to finish. Architect Seema helped us bring our designs to life and assisted all the way to planning permission approval by the local council. Communication was always prompt and in a timely manner by WhatsApp or email. Premiums charged are fair and reasonable but ultimately the service provided is exceptional which is what matters the most. They also provide structural calculations and building regulations which we are looking forward to working with the team again.
