Eco Island Sanctuary

A low-impact resort held above a sensitive island by lightweight framing, large shading roofs and a water loop drawn as part of the plan, not bolted on after it.

Note — self-initiated studyA self-initiated design study by Ionescu-Lupeanu Design & Engineering. Not a built project. This concept explores an approach to eco-resort architecture, structure, MEP and BIM coordination for a tropical island setting. It is not a commission, and no part of it has been built.

Masterplan.

§02 — Drawing what stays

The measure of the study is not how much can be placed on the island, but how little needs to touch it.

The site is a small, low island in the Indian Ocean: a shallow reef flat on one edge, a stand of mature vegetation at the centre, a beach that moves with the season. The study begins by drawing what stays. The tree line, the reef edge and the highest observed water mark are fixed first; the buildings are placed in what is left.

The plan is dispersed rather than massed. Guest structures sit in loose clusters along the vegetated spine, each one small enough to pass between existing trees without clearing them. Circulation is a raised timber-inspired walkway that touches the ground on points, not lines — the landscape runs underneath it unbroken. Arrival, dining and wellness are grouped on the more sheltered shore; the villas hold the quieter edge.

Two things are planned as infrastructure from the first sketch, not added later. The first is water: desalination, storage and wastewater treatment are given a location, a footprint and a service route on the masterplan, sited away from the reef and screened by planting. The second is energy: the roofs are oriented and sized to carry solar arrays, so the shading structure and the power structure are the same structure. The masterplan is read as four layers at once — landscape, architecture, structure and services — and the layers are made to agree before any of them is refined.

Density is kept deliberately low.

Architecture.

§03 — Proportion and shade

The architecture is quiet, horizontal and made of few materials. Large roofs do most of the work.

Each structure is a deep, low roof carried on a light frame, with the enclosed room set well back beneath it — the roof shades the walls, the walls shade the interior, and the shaded threshold between them is where most of the day is spent. Natural materials set the register: timber and timber-inspired framing, woven and slatted screens, mineral floors, lime and earthen finishes. The palette is restrained and warm, closer to the island than to the brochure. Colour is left to the landscape and the water.

Comfort is sought before it is powered. The buildings are narrow in plan and open on two sides, so the prevailing breeze crosses each room rather than stopping at it. Roofs are raised on a ventilated ridge to let heat escape upward. Deep overhangs and adjustable screens tune the light through the day, and openings are sized to the wind, not to the view alone. Mechanical cooling is treated as a supplement for the few hours that need it, not the default state of the building.

The result is an architecture of proportion and shade. Nothing is tall. Nothing competes with the trees. The framed view is earned by keeping the structure low and the roof long.

Structural strategy.

§04 — Lightweight, elevated, corrosion-aware

Everything arrives by boat, and everything that lands should press on the ground as lightly as possible.

The study answers both the transport and the touch of a remote island with a lightweight, prefabricated frame and a minimal foundation. The superstructure is conceived as a kit of repeating timber-inspired components — a small family of frames, beams and roof cassettes, sized to be craned or carried by hand and assembled by a modest crew.

Prefabricated component kit

A small family of repeating timber-inspired frames, beams and roof cassettes. Prefabrication moves the precise work off the island, shortens the time on a fragile site, and makes the connections repeatable and inspectable.

02

Engineered for uplift

The frame is engineered for the tropical wind case first; uplift on the large roofs governs the design, and the load path from roof to foundation is drawn as a single continuous decision.

03

Small, reversible foundations

Where the ground allows, buildings and walkways sit on screw piles or pad footings rather than continuous slabs, so the structure stands clear of the soil and the island can be left close to how it was found.

Corrosion-aware detailing

Fixings, brackets and any steel are specified for a salt atmosphere, and details are drawn to shed water and to be reached for maintenance.

MEP & sustainability strategy.

§05 — The services are the infrastructure

On an island there is no grid to lean on and no municipal main to connect to. The building services are the site's infrastructure.

Water is a closed argument. Fresh water is produced on site by desalination sized to real occupancy, stored, and distributed with the losses that matter designed out. Wastewater is treated on site — a sewage treatment plant (STP) scaled to the resort — with treated output directed to irrigation and landscape rather than to the sea. The desalination and STP footprints, their intake and discharge, and their service corridors are located on the masterplan and coordinated with the structure early, so the plant has a proper home and the reef is protected by distance and design.

Energy follows the roof. The large shading roofs are oriented and structurally sized to carry solar arrays, pairing generation with battery storage to cut the load on any generator to a genuine reserve. Because cooling demand is already reduced by cross ventilation and shade, the electrical system is sized against a lower baseline from the start.

None of this is offered as a built performance figure. It is a coordinated intent — solar, desalination and wastewater treatment drawn together with the architecture and the structure, so that the sustainability of the scheme is a property of the plan and not a label added to it. On a real project, capacities, discharge standards and environmental approvals are established with local specialists and confirmed through an EIA.

BIM & technical documentation.

§06 — One coordinated model

A roof carrying a solar array, the frame beneath it and the service route feeding it are the same coordinated object rather than three hopeful assumptions.

The study is developed as a coordinated model, not a set of separate drawings. Architecture, structure and MEP are built in BIM and checked against one another. The prefabricated frame rewards this directly: a small, repeating component family is modelled once and used everywhere, which keeps the geometry exact, the connections consistent and the fabrication information clean.

The structural model is developed in Tekla for the framing and connection detailing, and shared through IFC so that architecture, structure and services exchange a common, checkable model. Clashes are resolved in the model, before they become variations on site — the priority on a remote island, where a missed coordination is a second boat, not a second trip down the corridor.

The documentation is written to be buildable by a visiting crew: clear assembly sequences, schedules for the repeating components, and connection details drawn for the conditions they will actually meet. From concept to construction, the intent is a set that survives contact with a builder working a long way from the studio.

Local responsibility

For international projects — including the Maldives, Greece and other jurisdictions — local approvals, statutory submissions, code compliance and professional sign-off are handled together with local licensed architects, engineers, structural checkers, EIA consultants, coastal/marine specialists, fire consultants and MEP/utilities consultants. The studio is a technical partner; it does not replace local consultants.

§07 — self-initiated study
A coordinated intent, not a built performance figure.

A self-initiated design study by Ionescu-Lupeanu Design & Engineering. Not a built project. Read this study beside our Maldives resort design and engineering approach, where the same principles are set against real market, approval and delivery conditions — or the sibling island study, Hudhufushi Lagoon Forum (C-01). The disciplines behind the study are set out in our services, and the real, built work that underwrites the craft is our selected work.
