We recently had the pleasure of working with Marius, his skills and craftsmanship were truly outstanding! Throughout the construction process, his attention to detail was commendable. Every aspect of the project, no matter how small, was meticulously executed. Marius' expertise was evident in the precision of his work, and it was clear that he takes great pride in delivering the best possible results. Marius kept us informed at every stage, patiently explaining the progress and addressing any questions or concerns I had. This level of transparency and professionalism made the entire experience enjoyable and stress-free. Marius' dedication to quality was evident in the choice of materials he used, ensuring the durability and longevity of the finished product. He had an eye for aesthetics, ensuring that the final result not only met functional requirements but also looked stunning. Not only was Marius skilled and reliable, but he also completed the project within the agreed timeframe and budget. His efficiency and commitment to deadlines were highly commendable. In summary, I can confidently say that Marius' work is truly great.

Restoration & Refurbishment- 21 Apr 2023
Marius accomplished a difficult work for my property. We had a heavy leak difficult to identify which required a couple of investigations. He finally gave me the price figure and estimated time to do the work and he managed to do it in a successful way all the way through. He changed all electric work under the stairs, completely replaced new joists, plywood and engineering floor on top. He changed the damaged staircase, solve the leak problem without causing big damage. Thank you for your business. Will definitely hire again for my loft conversion. Would highly recommend!!! Thank you for your business!

Bricklaying- 8 May 2026
Gordon was amazing. He came within a few days on a weekend to repair the steps as they were dangerous. He did a great job, also repairing loose brickwork on a wall at no extra charge. Very reasonable price too. I can recommend him and will definitely contact him again for brickwork jobs.

Extensions- 23 Dec 2021
We originally asked Aaron to come look at the property before we purchased to understand the possibilities of a large extension. Since that point over a year ago Aaron has worked with us in refurbishing the existing house as well as building a large wrap around extension. The core team we had on site of Aaron, Dan, Karl are hard working, they care about what they do, and they are good fun to be around. Aaron also has a broad network across all the other trades - all of which did a great job on the project. I would certainly recommend them for any work you are considering.

We recently completed a large renovation which included extending our kitchen at the rear of the property, changing levels in the garden and converting our loft with an additional bedroom and en-suite. Ben, Steve and the rest of their team were amazing throughout. We had difficulty moving out of the property as our short term let fell through but the team worked tirelessly to enable us to ‘live in’ whilst much of the build was going on (which I know wasn’t ideal!) I highly recommend Integrated Homes as Ben and Steve were so knowledgeable, considerate and professional in their work.

Damp Proofing- 11 May 2026
My experience with Samuel was excellent. He provided a professional, comprehensive, and high-value damp survey for my basement. The final report was very thorough, including a detailed technical assessment and numerous photographs that clearly explained the situation. What really stood out was his willingness to answer several follow-up questions regarding the specific remedial work he suggested. His expertise helped clarify that the issues were environmental rather than structural, which provided great peace of mind. Highly recommended for anyone needing a clear, honest, and professional assessment.

Architecture- 27 Nov 2017
I contacted Marius because he had good reviews and wanted someone reliable and capable so design a single story extension with large external and internal bifold doors. I wasn’t disappointed - Marius has been excellent throughout the whole design process and produced drawings to a high standard which met our requirements. Marius was an excellent communicator and always available to give advice when required. Further more, he went out of his way to contact local authorities regarding any questions I had at no extra cost to clarify any uncertainties. I would highly recommend his architectural services - he was good value and very professional.

Extensions- 13 Nov 2020
Well, I do not usually write reviews, but this time is an exception. So after getting a number of quotations, I decided to go ahead with Fredi. The process was very smooth throughout, Fredi is a great individual and a reliable professional. The plan was to build a rear extension, but working with Fredi, we decided to commission him for the patio, changing all house flooring, kitchen, and two bathrooms. All have been delivered to completion with top-notch results. Most importantly, we have now a new family friend...Fredi the builder!!.. my kids say :)

Extensions- 21 Jun 2017
COWBOYS! Absolute Nightmare! Marius left the job incomplete, after repeatedly demanding more money before completion! Not to be trusted! Workmanship wasn't as good as he would lead you to believe, I have pics & videos of: Cigarette butts in mortar. Bricklaying in the rain, not water-tight roof/felt work, drainage, unsafe electrical work which needs to be redone. Left my neighbour side of roof damaged + with a hole now for a month. Damaged door/table/gate. Of course, he denies any wrongdoing Please be very careful if you have to use this fraud. Get a FULLY detailed itemised quote! Draw up your own contract - do not use his. Do NOT ever pay CASH. Produce a schedule of works - pay him ONLY when the specific task is 100% complete - leaves lots of work unfinished but then lies claiming its complete at interim payments. Get a FIXED price for every aspect of work - do not have "TBC" or ambiguous costs - if he can charge more - he will. Do NOT use his electrician, cringeworthy attempt to "price up" a simple job and damaged roof. Buy ALL Materials yourself OR require receipts for anything he buys. Request ALL Invoices. Ensure he follows specs - offered me £250 off total job cost, if I used a inferior type of rooflight to the one required in spec. Ensure he doesn't keep rubbish on site, Hire a skip. Keep all communication on record, email, text, even voice record him as he is a pathological liar. Very dishonest, delusional and frankly embarrassing.
