Sustainability was a core component of the project. The
building, with a concrete frame and masonry walls, was
uninsulated and mostly single-glazed. Energy use reached
315 kWh/m²/year, far exceeding new-build standards.
GRID tackled this by decommissioning the gas-fired
communal heating system, replacing over 2,000 windows,
insulating roofs, installing more than 40 air source heat
pumps, and switching to renewable electricity, while the
Dolphin Square management team introduced green
leases to align with tenants’ ESG targets. All upgrades
were sensitively integrated within the constraints of the
Conservation Area. Roof plant enclosures were reused or
discreetly extended. New MVHR systems were carefully
designed, with circular louvre terminations that
referenced the cast-iron structural ties of the original
architecture. Replacing windows with heritage sash
systems matched original profiles while improving thermal
performance.
and mechanical smoke ventilation. Kitchens were relocated or expanded, bathrooms upgraded, and corridor
services housed in bespoke soffits. MVHR ductwork was
neatly integrated within new ceiling coffers while corridor
services were housed in bespoke soffits for a clean and
cohesive aesthetic.
In summary, Dolphin Square’s restoration serves as a case
study in preservation and innovation. Through thoughtful design interventions, pioneering engineering solutions,
and a commitment to community well-being, GRID have
successfully revitalised one of London’s most distinguished
residential landmarks. By safeguarding its historic character and integrating forward-thinking environmental
strategies, Dolphin Square continues to stand as a model
of resilient urban living – one that evolves with the needs
of its residents while remaining deeply rooted in its
architectural legacy.
Roshan Ramlugun, Residential Sector Lead at AXA
Investment Managers, describes his experience working
on the project: "As a client of GRID Architects on the
restoration of Dolphin Square, we sought a partner who could
balance the estate’s rich architectural heritage with the demands of modern living. GRID’s approach was meticulous,
respecting the fabric of this iconic development while enhancing
its residential offering. Their expertise in sensitive restoration
and thoughtful design ensured that upgrades—whether to the
apartments, communal spaces, or landscaping—were executed
with a deep understanding of the building’s character and history. The team was collaborative, responsive, and committed
to delivering a scheme that not only preserves Dolphin Square’s
legacy but also elevates it for the next generation of residents”
In Phase 1,363 apartments across Rodney, Duncan and
Beatty Houses were transformed. Each house received a
tailored interior identity while retaining a consistent
material palette. Entrance lobbies and lift areas were redesigned with new finishes and fluted timber panelling,
echoing motifs from the main entrance and reinstating
the building’s historic character.
The residential accommodation itself also underwent
thoughtful reconfiguration. Many of the 1930s layouts
were outdated, with small, cellular rooms and dark
kitchens. GRID Interiors introduced open-plan living
made possible by new fire strategies, including sprinklers
