Really helpful, and quick and responsive

George did a great job with our extension plans, and really helped with communication to our local authority when we received pushback on the initial design. Both he and Kate were really responsive when we needed to make changes and helped me through the whole process.

Great service; council approved straight away

George, Kate and team were super communicative, and managed to get our loft plans approved first time (in a conservation zone).

Were very pleased to be working with them.

George was extremely helpful from start to finish and the plans went through with extreme speed.

Admittedly I did call him an Aussie by mistake and he kindly corrected me that he's a Kiwi not an Aussie.

Would definitely recommend their services if speed and quality is your no.1 priority.

Just absolutely amazing.

Smooth and efficient service

The building survey for our loft converstion was organised very efficiently, with minimal disruption to me and my family despite us all being in the house at the time.

The architect plans were put together very quickly and Fast Plans were on hand to answer any questions we had over the phone and were also prompt with replying on email.

Fast Plans provided clear, step-by-step instructions on what the planning approval process was, as well as a comprehensive overview of any additional measures I had to take (party wall agreement, building control, etc.) to ensure that there were no delays to the start date of our building project.

Disappointed in their service

George came highly recommended to us. Our experience started well enough, but once payment was made, then the cracks started to show. We had to chase to get drawings that weren't included in the original plans sent, emails were not always responded to, incorrect information was given regarding the sizing of insulation needed for the extension, and when the steels were ordered, and the measurements were incorrect, and was then subsequently blamed on the builders, costing us extra,delaying the build by almost a week, and fabricators were now having to come to our home to make changes, we'd had enough. No apologies were ever received, but new drawings were sent over with the changes made to the steels to now show correct information. Would not recommend after the service we received.

Hi Dyan, thank you for your feedback.

First of all, I am sorry to hear you’ve had a frustrating experience - this is not what we hope our customers feel after they have worked with us, and so we’re disappointed this is the case.

I accept that one of the steel beams for your project needed a steel plate affixed to the top due to a wall thickness being greater than we specified for. You contacted us about this with request that Fast Plans cover half the cost of having a fabricator come to site to weld the plate on to the steel. As I explained to you, it is your builder’s responsibility to check all dimensions on site before ordering materials and our terms exclude us from any liability when this is not done. We carry out a ‘non-invasive’ survey and don’t drill holes in to walls to check their thickness so discrepancies like this can and do happen in our drawings. The important thing is we promptly provide updated drawings at no cost when this occurs but we do not contribute to the cost of the building materials or labour.

We completed drawings for your project in November 2023 and your builders started work shortly afterwards. I was personally happy to answer many questions you relayed to us from your builders and reviewing our emails I see that I did convey apologies for the missing steel plate by email in March when we sent revised drawings.

Once again, I am sorry you are both frustrated by these unplanned costs, but we do not believe that Fast Plans has failed in our responsibilities and commitment to you, but nonetheless we apologise for your disappointing comments and feedback.

Regards,
George

A top rate service for building/extension plans

We engaged Fast Plans to draw up plans for a loft conversion. From the off George and Angela were always available to discuss the project and broke down every part of the process clearly so that a novice in such matters (like myself) was able to understand the technicalities. They were quick to answer any queries, always emailing me back the same day, and completed the various stages of the process, including submitting the plans with our local authority for planning permission in a timely fashion. All in all the entire process was efficient and hassle free and I wouldn't hesitate to recommend Fast Plans to anyone considering a project of this nature.

Very straightforward process

Very straightforward process, Fast Plans holds your hand through the whole process. I like how simple they made the designing, drawing and planning application process which is often quite a daunting project to undertake!
