B1 Block holds a distinction shared by only one other block in all of Janakpuri: it is one of just two blocks — B1 and A2 — where 419 gaj plots exist in the DDA residential inventory. These are the largest standard residential parcels in the colony, and they make B1 a destination for buyers seeking maximum land and build potential on a single title.

B1 is also, by location, the most metro-connected block in Janakpuri. Janakpuri West Metro Station — the interchange where the Blue Line meets the Magenta Line — is barely a one-to-two minute walk from the block. From here, residents reach Rajouri Garden, Connaught Place, and Dwarka on the Blue Line, or Hauz Khas and the Botanical Garden corridor on the Magenta Line, with a single interchange at their own doorstep. No other Janakpuri block sits this close to a two-line interchange.

The block is anchored by Mata Chanan Devi Hospital (C-1, Janakpuri — a major multi-speciality facility immediately adjacent), with Dashmesh Hospital, UK Nursing Home, and Sai Nursing Home also nearby. Daily-needs and retail infrastructure is dense: Gandhi Market and Shastri Market are within walking distance, and Janakpuri District Centre — the area’s primary commercial hub — sits roughly a kilometre away. A B1-Block community centre serves residents directly.

Plot sizes available in B1 Block are 150 gaj, 225 gaj, 325 gaj, and the rare 419 gaj. All three streams are active — builder floors for end-user families, plots (including premium 419 gaj parcels) for investors and self-constructors, and collaboration arrangements for plot owners who want to develop without deploying capital.
