  • Structural Engineer needed

    Here was my ad..."We are doing a loft conversion and kitchen revamp and need a good structural engineer to do the calculations etc."
    He came, measured the loft only and left. He had to return to do the kitchen which he said was not in the original spec (see above). All he gave were measurements. I already had those, I needed the structural calculations for my builder. We had paid the full amount already.
    We then had to pay another engineer to come for roughly the same price to do the job I asked for. So we have paid twice.

    NP Essex Structural Engineer's reply:

    I did my first site visit but the client was not there to explain what exactly they are looking for, as the plan they had already provided was very basic and unclear, after I sent my drawings he send me an email and explain that there are some other work, we arrange another site visit but surprisingly!! he did not attend on site again and there was not any body to explain what exactly he needs properly, I provided the revised drawings base on the information the guy explained to me on site and sent it to him, he never contact me again and I thought all is OK till I have received this feedback.

  • Extension built

    Very very disappointed after submitting for second time with the different architect.
    I contact the council to find out the reason of the refusal . Been told the drawing was not clear . I choose NP Essex structural because it was cheap. but I end up paying twice and more very disappointed again.

    NP Essex Structural Engineer's reply:

    It's very simple, as explained on the site, if someone wants to have an extension in a land that doesn't belong to him, it will be refused. However, you insisted and this is the result and I don't believe you should be disappointed.

    Thanks for your feedback and good luck!

    I would absolutely recommend Pirooz.

    Pirooz and Neda were a pleasure to work with, and responded quickly to questions. Neda was very good at taking the time to explain our options and respond to queries that we raised. They seemed to have a lot of work on at the time our job needed doing, so it sometimes took a week or more to get drawings and amendments back. But otherwise very happy with the service and end result and would definitely use them again/recommend their services for other projects.

  • loft conversion

    Just used someone else, you will get a much better service for your money. I used NP Essex to produce a plan, structural drawing and the structural calculations for a loft conversion. The plan had a number of critical mistakes with a doorway and staircase that simple did not fit or conform to building regulations. The service was very slow, for what was a simple project. Furthermore the communication was very poor with NP needing to be emailed repeatedly before they would respond. To cut a very long story short, save your self the hassle. The other negative reviews are a more accurate reflection of the service you will receive.

    NP Essex Structural Engineer's reply:

    Unfortunately some people think that the loft conversion is kind of DIY jobs which is not.
    It is necessary to hire an experienced contractor who understands the structural drawings.

  • Structural engineer

    NP Essex was very helpful doing structural design and calculations for a Bungalow to House conversion by adding a first floor extension. After site visit, he has done it in a very efficient and very cost effective design, where other proposed designs by others could have cost us lot more to build. He was very helpful answering all my questions after the design was provided and building control approved the plan without any further questions.

    I would highly recommend NP Essex for any Structural designs and calculations.

    Many Thanks!

  • open plan kitchen

  • Structural engineer needed

    Pirooz came very quickly to do the work and was very flexible in terms of offering calculations and plans for different options, as we weren't sure exactly what we would have done. He gave the plans and calculations quickly and also provided some additional advice and plans for an extra thing without charging any extra. Very good value for money and a very pleasant experience as his communication was excellent. I would definitely recommend to others.

  • Single storey rear extension

    We approached Pirooz to help with structural drawings for a planning-approved single storey rear extension of a mid-terraced house - in order to approach builders for quotes and also for building control approval purposes.
    Pirooz was able to arrange a site visit promptly and quickly understood our plans even though we only had a "layman-drafted" floor plans and drawings.
    Pirooz was professional at all times and was happy to answer some of my "novice" questions. The final structural drawings and calculations was exactly as I requested and suited my needs, and during the process, Pirooz managed to turnaround some changes / corrections fairly quickly.
    All in all, I will recommend Pirooz for any similar jobs.

    Pirooz was highly competent, understood what I needed and was informative and knowledgeable on his site visit. He supplied the structural drawings before our agreed time and at a competitive price. I would certainly recommend Pirooz.

  • plan for rear double storey extension‏

    He has no planning permission knowledge. He took 30 days to present the initial floor design for a simple extension, took 33% money on first meeting. When he gave the single page design, I asked it requires 4 types of design not just one, then it said, I can buy 2 type from somewhere else, one more he can try to prepare, but need next 33%.

    I asked him to give next 33% after planning approval as there was fully building regulation design, application, and approval was remaining.

    Then he said he can't wait for the outcome of the planning permission, as his design won't get approved by council. When I asked the reason of rejection after preparing the design, in his own word in the email: "in my opinion it is very unlikely to achieve the permission for full width first floor extension."

    When he prepared the initial design, I sent a mail:
    "Hi Pirooz,

    Can you see some of the minor amendments please? The main one is for the larger coverage of first floor, rest are just about windows.

    Kind Regards,
    Manish Kumar"

    And he replied:
    "Hi Manish

    All is OK, but as discussed on site if we do the all width first floor extension, you will not have any window for the existing small bedroom. what do you think?


    Do you think he mentioned anything that full coverage will have any risk of rejection? He prepared the design after his mail. I already filed complain with council, to get full email discussion, ask me at

  • Kitchen extension

    Pirooz has been excellent from start to finish. He is very polite, keeps to his commitments and did an excellent job in drawing up plans for an extension, garage build and other structural modifications. He always responded very quickly to my questions, and gave me plenty of good advice. He is unique compared to others in the trade for his perfect service. I would thoroughly recommend him to others

  • Internal house layout changes

    In all honesty, you can have a far better service, drawings, and after sales experience from pretty much anyone else for the money charged here.

    Be prepared, that the drawings will be very simple, and hardly professional, and if you do make any amendments before final pay, there will be no help provided.

    We did get permission for the extension, but smaller than wanted due to poor advise from Pirooz. He does not know the law as well as he should've if suggesting things to people. Sadly we only found out we could've applied with different depths when it was too late.

    Would certainly not use again, and not recommended if you do not know what you're talking about 100%. Seek advise from someone else.

  • Provide calculations for a lintel

    Pirooz was polite, professional and prompt in issuing his report. He was happy to answer my queries on the report, and replied quickly. I would recommend him.

  • Plans for kitchen extension

    Although things started off well, this went disasterously wrong. At first, Pirooz could not do enough to be helpful. However, when I had paid in full for the plans and left feedback, he stopped answering my queries. When my build started, it became apparent that the internal measurements were wrong. Pirooz has forgotten to allow for the cavity wall, which meant my extension was 20cm too small widthways, and 10cm too small lengthways. I wrote to him 2 weeks ago, but have had no reply and no apology. My builders said that the structural part of the plans was very basic; I was lucky to have excellent and experienced builders who were able to sort this out.

    Sadly, because of the lack of a reply, I can only assume that Pirooz does not care about his clients or his reputation, but is just interested in getting his money quickly. I asked to rewrite this review because I don't want anyone else having these problems. This was a very basic mistake which should not be made by a professional, and at the very least an apology and refund should have been given.

    NP Essex Structural Engineer's reply:

    I did many extra work for Catherine and received positive feedback but she contacted me for more help and I was out of the UK and couldn’t reply her email; after I back she changed her feedback from positive to negative! I was surprised and after meeting I found out that although I gave her some advice, she made two important mistakes:
    1- Hiring a builder who does not understand structural drawings. I have put the structural drawings on my MyBuilder profile and it just shows if for this small extension job is it good enough or not and also it shows that there will be cavity walls.
    2- Ordering the new kitchen base on drawings, for many reasons she should order it after the construction work, especially for the small extension as hers.

    Building regs wanted some more calculations with our walls so I needed him to come back and explain more stuff on the calculation and Pirooz came down again. I had three other tradesmen working at my property at the same time; my builder, a plumber and an electrician and even they were really impressed with Pirooz's timing and more importantly how he explains stuff. It has been a joy to work with him and he is a real gem to have as a contact. I am more than happy to recommend him for any structural work calculations.
    I got my structural calculations in less than 24hrs!
    Thank you very much again.
