Top Service

Mohi is knowledgeable, professional and he absolutely knows everything about planning. Our planning application was refused 3x by Havering Council, under a different Architect We are losing hope and in so much stress about the whole process until I found Mohi by searching for Architect/Structural Engineer on Google. He was a God send. Mohi re-designed our plans, spoke to various people at Havering planning dept and discussed what we needed to change, add, or alter in order to get planning. Mohi explained everything to us every step of the way, I can text him even late at night and he is always there to answer questions and concerns we had (which was a lot!) nothing was too much, he never made us feel

unwelcome or a bother which if I’m honest I was most probably bothering him with my endless questions but he was always there to re-assure us patiently explaining what we don’t understand. After so many bureaucratic issues with the council, he got our planning approved! The dealings we had with the Council was a complete nightmare, but because of Mohi’s expertise, talent in designs, and ‘never give up’ attitude, he got us there in the end. Without Mohi, we wouldn’t have our dream house today. If you need an Architect and structural engineer, believe me, you will never find a better person to do these jobs for you. I highly recommend Mohi and his team (special thanks to Abdul) you will not regret it! He deserves more than 5 stars – Thank you Mohi and Abdul !!!

Ist Class Services

I would give six stars if I could! I called GR Engineers at 5pm in a panic looking for an urgent structural survey, as the sale of our property (and our entire chain!) was at risk.

Mohi called me back within ten minutes to book an appointment for the following morning. His inspection was very thorough and he assured us of his findings. Mohi was even able to issue a written report on the same day, which really saved the day for us and our entire chain.

Truly brilliant service, particularly at such short notice. Thank you Mohi!

Mohi provided an excellent service at fairly short notice. The plans and drawings were high quality and enabled a first time acceptance of my planning application. My builders found the details easy to understand which ensured right first time construction. Would use GR Engineers Ltd again, many thanks.

Steve Bradley - 10/10/2022

Everythig is the Best

I am pleased to work for this company. Most of the drawings we produce are checked by their expertise again before sending to the customers or councils. For the exceptional or critical cases the structural engineers arrange the board meeting with us and we all choose the best and common option at the meeting. The structural engineer who is allocated for a project always communicate with us for any further changes based on the structural elements layout. The outcome is most of our projects get approved and the company uses the best photos of the projects on it’s website.

Md Kamrul Islam - 19/2/2022

We are very happy with his services and would definitely recommend.

Spot on Service

I was in a process of selling my house. The buyer’s solicitor was asking for the documents of our chimney removal. We called GR ENGINEERS Ltd for the structural calculations of the chimney support. The engineer immediately attended to our site and observed the chimneys position. The steel design was done in a few days and we did not have to higher the scaffolding for installing them as the engineer designed those steels in splice and small pieces. We have sold our house now with the approved certificate from building control.

Thanks to you guys . I will surely use your services in future.

Mohi provided the plans and engineering calculations for our loft conversion and rear extension. He liaised with Bromley Council and Thames Water on our behalf to get all the required planning permissions. He also dealt with a complicated party wall agreement and was very accommodating in updating our plans as required.

We did a loft conversion and everything went smoothly. The drawing and structural calculations were done promptly by Mr Mohi and we didn’t have any problems with council. Mr Mohi was very kind and approachable and he gave us a lot of professional advice. It was really nice of him to pop in during the construction time to check if everything was ok.

Outstanding Architectural Services

I had my drawings and design done for 6 meters Kitchen extension and summer house by GR ENGINEERS LTD. 1st from the name of the company, I thought, this one only serve the engineering stuffs. When i approach them for drawing, i found they delivered me neat and clean drawings. They have got the good terms with council’s planning department. Mr Mohi Ahmed, did not charge me any extra for any consultation with council’s planning department or any amendment in the drawings. I have checked the price of other cheap architects. Their initial price for drawings was cheap but some of them were charging £250 for any small amendment in the plans or structural calculations. I added my chimney stack removal for free of charge on Mohi’s service. After the projects were completed, i allowed him to take photos of the finished work. I am recommending him to my friends and families for the architectural design and the engineering calculations.

EmadurR - 18-07-2019

High standard of work – 5*

Mohi has been so helpful for my plans of 2 storey side extension and loft conversion. He came up with idea of building the loft 1st then 2 storey side extension. I am letting the side extension part with a separate side and rear access from outside. All the structural calculations were done by him and they were accepted by Redbridge building control. During the construction time, he advised the builders about many technical things. The cost of the drawings and structural calculations were very reasonable compared to his services. I highly recommend him for the architectural drawings and the structural calculations.

NaveenkumaJ - 13-06-2019

Excellent, Efficient and Reliable! Do not overlook! – 5*

I was saved by Mohi after a terrible experience using one of the big national firms that delayed my build.

Mohi picked-up the drawings and amended them where he saw there were issues, and presented his findings clearly and competently.

Turnaround was in no time and I am very grateful for this after being delayed by the previous firm with excuses of which Mohi gave none – he simply did his job brilliantly at that.

I trust Mohi and GR Engineers, and highly recommend his services from drawing to structural calculations etc.

The cost was very reasonable and of course this is a big factor when finding an Architect/Engineer.

I have referred my clients to him; as I know how well he undertakes his work and will continue to do so.

Do not overlook for a national firm as there is a marked difference!

DavidB - 21-05-2019

Professional and reliable

Mohi Uddin is extremely professional and proficient. He has been there from the initial process till the end. When ever required, he has liased with local council with regards to drawings and calculations. We put our complete trust in him to resolve any matters raised by building regs. and he never disappointed us. Always made site visits upon request. He further went to rescue us when the first appointed builders absconded the project. He introduced us to a friendly and reliable builder who completed the unfinished project for us. We are very grateful for his service and highly recommend him to anyone looking to hire an architect and structural engineer. A**********

Efficient and Wonder services by Professional – GR Engineers Ltd – 5*

I am lucky to involve Mohi with his company at my rear extension and Loft conversion works. He and his team have done all the drawings and structural calculations on time. He has never charged me for any amendment of the drawings or planning. When I had critical time with building control and builders and do not know really how to deal with those situations , Mohi visited on my site and dealt with queries from building control. He explained my builders about the necessary works to be done on site. As a result the building control’s inspector was happy for the overall works have been done by my builders and i have received my completion certificate.

GoldSuitcase40 - 07-02-2018

Absolutely superb service-six out of five star – 5*

I was unable to obtain local council approval for calculations related to an application for a single storey rear extension and loft conversion. The council continued to identify issues with submissions made by the engineer I had initially appointed which was delaying the completion of my project. I decided to cut my losses and appoint GR Engineers. Within 10 days they inspected the site, produced revised calculations, discussed the situation with the local council and submitted revised calculations which were subsequently approved. Within that time they also met my builders and discussed the impact of the changes to minimise the delay which saved time and money. I highly recommend using GR Engineer Ltd for all structural engineering needs

KeithU - 01-11-2017

Within a week the plans had been drawn up and submitted to the council who approved them without any querys.
We now have an amazing house that is better than we could ever have hoped for.

This company is actually really good, I used another company from this site yell.com but the guy took six weeks saying my proposal for back extension has been declined.

So I spoke to GR engineer: Mohi, he advised on very small adjustment, re negotiated with the planning committee and then got approval with his new drawing plans as well all in 6 days. I should have used GR from the start so by now I would have a new bedroom and kitchen. GR also managed and organised to source the builders for me who has already started the work.
