Flat Refurbishment

"" I used Alt Constructions for the full refurbishment of my new flat. From start to finish the team was great and they worked along with my architect, providing highly qualified workmanship and adding real value to the project.[...].

I was impressed with the quality of finishes, their communication skills and positive attitude onsite. I will definitely recommend this company to anybody.""
