  • After working with Spektra for some few months, my conclusion is that the company simply delivers just when you least expect. Their attitude towards finesse, details, time and delivering the overall project is just PRICELESS. Will always recommend them...ANYTIME

  • I highly recommend Spektra to a potential client who is looking for a ‘value for money’ project. They are very sensitive to client needs and very professional in their advice. It takes a lot of effort to conceptualize their ideas but when it materializes, they are always right and on top of that you can’t bypass their integrity

    Designs by Spektra can be considered world class in terms of beauty without compromising safety and security. One may easily be tempted to think that they can only be patronized by the rich in society, but make no such mistake, the ultra-modernly beautiful, safety conscious and environmentally friendly designs by Spektra are competitively priced

    Spektra built the design to look exactly like the 3d impression to my amazement. The works were so precise to design I almost concluded they were imported ready-made. Everyone who enters the shop always asks who worked on the interior. Spektra has kept in touch even after the project and I always look forward to my beautifully designed desktop calendars at the end of every year.
