Professional and high quality company used for structural wall removal project

We contracted Constructum Code after getting various quotes from other companies to knock through a load bearing wall in our house and put in a steel beam on new brick piers.

Ben visited us to discuss the work beforehand and came across as very knowledgeable and we were given a very reasonable quote in writing. Ben highlighted areas of potential difficulty in advance based on his experience and proposed solutions which ensured there were no surprises or additional charges once work had started.

The team on site were extremely polite and professional, led by Arvis who came across as very experienced and ensured that the work was done to a high standard. They were hard working and went above and beyond, adding in extra stud work for free which was not included in the original quote and particularly with the clean up. They even helped me clear up debris from other work ongoing in the house.

The communication from the team over the phone and by email were exceptionally professional and responsive throughout the project, as well as the contracting and invoicing documentation.

Overall the experience was stress free as this company was exceptionally professional and reliable and I would not hesitate to use them again.

They did my kitchen extension and did a really good job. They’re a good-sized company — small enough to be flexible and tailor things to your needs, but big enough to maintain proper quality standards. No cowboys on their team.

Ben, who handled the initial communication, didn’t come across as pushy at all — very straightforward and upfront.

Very happy overall!

Happy with our kitchen extension

Construction Code did a great kitchen extension for us. The project was long and full of challenges but Ben managed all aspects impeccably and kept us informed through every stage. We also really appreciated his honesty as he tried to guide us to the most cost effective and quality solution as opposed to just the most expensive. Any issues that arose or things we spotted that needed fixing, he sent his team to rectify asap. The result...a fabulous kitchen lounge extension with a separate shower room and utility. It's been a lot but we're thrilled with how it's turned out.

Ben and Raimis were excellent

Ben and Raimis were excellent.
They repaired our ceiling super quick.
I decided to do extra work to other rooms in our flat in Chiswick and they fitted this all in no problem, all done within 2 weeks - so quick. All work done to a very high standard and we’re so pleased.
Ben is great with communicating on all aspects of the job.
Would highly recommend and will definitely use them again.

Top Quality Extension

Ben and the team at Constructum Code did a fantastic job of our ground floor rear extension.
Consistent communication throughout and very high quality of work.
I'd definitely recommend to others and will likely use again for future projects.

Used Constructum Code Ltd for some internal works — knocking down a wall, redoing the ceilings, and updating the electrics. Proper job from start to finish. They were tidy (which was a big deal for us), respectful of the house, and took pride in what they were doing. Can’t fault them.

Great job

We turned our garage into a little home office and used Constructum Code Ltd for the job. I was a bit nervous at first but they made everything easy to follow. They listened to what we needed, kept within budget, and the finish is excellent. No mess, no hassle — just got it done. Cheers guys!

Constructum Code Ltd did a loft conversion for me. The team worked well, finished on time, and the result matched what we planned. The price was clear from the start, no hidden costs. There were small delays with materials, but nothing serious. Sometimes I had to ask for updates myself, but overall, the process was smooth, and the work was done well.

Construction work on our loft was completed in February 2024. Based on an individual project. The loft is relatively small 135 m2. It took 4 months from the first contact to the company to the acceptance certificate for the delivery of work. The construction was clearly organized, all difficult situations that arose were resolved quickly. The house turned out to be good. Growth and success to you in your difficult business and more grateful clients👍🏼Top recommendations 🤓💯😉

Amazing service from Ben and his team

Amazing service from Ben and his team. Available 24/7 if I wanted too. Always a phone call away for queries etc. Ben offered us valuable advices when we had our kitchen extension built. The work of his team is neat, précise, well executed. An extremely polite and respectful team.
Ben and his team will be first on our list when we decide to have more done in the house.

Side extension, great job!

I have a side extension for the ground floor maisonette in Twickenham done by Constructum Code recently.
Excellent professional job.
Very good planning, everything was done according to initial plan and within the budget. No hidden expenses, no surprises here.
The team was very responsible, with great attention to the smallest details. Any issues or questions has been sorted out promptly and correctly.
The surrounding area during the work was kept clean and upon completion everything inside and outside the house was clean and tidy.
I would recommend Constructum Code to everyone and I know for sure who is going to do the next project in my house.
