Here are some of the most prominent upcoming / recently launched apartment projects and large residential developments in and around Colombo (summary, location, developer and current status). I searched recent Sri Lankan property and news sources — see citations after each item.

Other things to watch in Colombo’s residential pipeline

• Port City / Colombo International Financial City (projects and towers) — several luxury condo proposals and mixed‑use schemes are linked to the Port City precinct; keep an eye on new launches tied to that precinct.
• Government/NHDA redevelopment programs — large government apartment redevelopments were announced for Colombo district (plans to redevelop older government apartment complexes beginning around 2026), which could influence supply and neighbourhood dynamics. (en.wikipedia.org)

Quick buying/investor tips for Colombo off‑plan apartments

• Confirm developer track record (completion history and quality).
• Ask for BOI approvals or foreign‑buyer facilitation if you’re investing from overseas.
• Check transport links (expressways, rail, Port City access) and expected completion date.
• See if the project has a condominium management authority / strata plan and clear timelines/penalties in the purchase agreement.
• Get up‑to‑date pricing and staging (prices can change quickly due to exchange rates and local market conditions).

If you’d like, I can:

• Pull the latest launch/pricing pages and recent news for any 2–3 of the projects above and give exact launch dates, current unit availability and typical price ranges; or
• Prepare a short comparison table (location, developer, expected completion, typical unit sizes/prices) for your top 3 choices.
