Spectra Constructions in one paragraph
Spectra Constructions has a mixed delivery record in Karnataka RERA filings: 60% of registrations needed no extension (3 of 5 crawled Bengaluru registrations needed no extension). 1 of 3 under-construction projects are past their original RERA completion date, by 18 months on average (worst 18). No complaints are recorded against the promoter entity at K-RERA. The median Spectra Constructions project scores 61/100 on investment merit (above the Bengaluru average); the best, Spectra Reserve, scores 65.
Delivery is judged on extensions filed, not on handover dates, because RERA records extensions reliably and handovers late. Extensions are common across Bengaluru; compare the rate with other developers below.
Projects past their original RERA date
| Project | Months overdue | Extensions | Built · booked | Complaints | Score |
|---|---|---|---|---|---|
| Spectra Raaya Marathahalli / Kundalahalli / Varthur | 18 | 1 | 100% of schedule · — | 0 | 49 |
Overdue is measured against the completion date in the original registration. Many are covered by extensions, which RERA grants for up to a year at a time.
