Highlights

“I liked the work of this company’s specialists in finishing my new turnkey apartment. I received the manager’s response as quickly as possible, discussed the project and agreed on a meeting. Accurate calculations were made on site and deadlines were determined. I was pleased with the repair and overall cooperation with this company, I can recommend it!”

Andrew BaconFreeIndex5.0 rating

“We ordered the design and renovation of a small two-room apartment from the company. Thanks to them for the quality work done, I especially liked the kids room for my two daughters - 7 and 14 years old, now each has their own corner and no one bothers anyone. I also liked how the bedroom was made, everything is stylish, modern and comfortable. Thank you!”

Tissa OlimbaFreeIndex5.0 rating

“They built me ? A conservatory with frameless glazing, in the form of a summer house. I am pleased that we chose this construction company as the contractor, which fully met our expectations.”

Detailed reviews

Henry Shuller4.0 / 5 ·

The guys built a 210-square-meter guest house (3 parking spaces on the first floor, 3 guest bedrooms with bathrooms and a guest house on the second floor) from ground in 3 months. Built box, roof, exterior, windows. Quickly and accurately, on time and on budget. Professional at his job.

Professionals in the field of renovation who were able to turn our apartment into a modern loft in a short period of time. Thank you for your individual approach and interesting design solutions.

Thomas Connor4.7 / 5 ·

We chose the Constructum Code company based on reviews. We were completely satisfied with the company's services. They completed it without delays and took into account our requirements. The object was completed under the guidance of the foreman: Benas.

Good company! They made full flat refurbishment, very quickly and efficiently! All materials are of good quality! I recommend this company, a good website with a large number of projects, very involved managers, they guide the client until the start of construction!

Marco Russo5.0 / 5 ·

Finally! A dream come true! Today we received the keys and moved into our new home! I would like to thank all Constructum Code builders, no complaints. And special thanks to Ben, and also to the foreman John for his humane attitude towards our family!

Paddy Haes5.0 / 5 ·

Absolutely fantastic job done by Constructum Code Builders and their entire team. They totally transformed my apartment and managed to carve out 4 bathrooms from the existing 2. Their finishing and quality of service was of the highest standard. I would recommend them to anyone planning an extensive and complicated renovation. I’m specially grateful as we did this entire project long distance over the video calls and WhatsApp pics. Would always go back to them for any future projects or works!

Nanoteqa Ltd5.0 / 5 ·

Fully professional building contractor! Made our loft (office room) in 1 month period. Gave best quality and comfortable price! Will use in future again ++++.

Never pay a large deposit up front. Agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow. Both are red flags for an unaccountable job.
