F-Line Designs are very professional! They have been very patient with me and my family in getting the best design solutions for our rear extension, internal refurb and dormer extension for our home!
They do everything from stage 1 to the final stage- so you’re in good hands. Quite flexible and open when working with you.
Communication= Great!
Efficiency= Great

We will definitely work with them again on future projects!

I employed f-line designs a few months back to draw plans for a substantial front and rear extension for a property. Fay at the company not only got the planning through in excellent time but was at all times through this stage, communicating with me to ensure I had in place everything I wanted and continued to update me throughout the process. What made her stand out for me was that she easily understood everything that I was trying to achieve with the property and turned a vision into a reality. I would highly recommend her to any prospective home owner, landlord or developer. I shall definitely be using her brilliant services again very soon.

We used F Line Designs to get our Double storey side and rear extension in the borough of Hillingdon. Fay and her team are extremely professional, knowledge and responsive.

They went above and beyond to work around the Council’s restrictions ensuring a attractive design was maintained and internally the layout was still functional.

I highly recommend them as they also did our structural drawings. Makes life easier when multiple services are available.
