Longevity Istanbul: Interiors Designed for Measurable Health
Longevity Istanbul is, increasingly, a design brief rather than a clinic appointment — and Istanbul is one of the cities where our studio can point to completed, measured work. Sabina Malikova Design Office has delivered both a medical interior and a residential retrofit here, each documented against the four pillars of the Longevity by Design methodology: circadian lighting, biophilia, air quality and acoustics.
Completed work in Istanbul, with the numbers attached
Two Istanbul projects anchor this page, both reported as studio project data. Dripfy Clinic Corner Istanbul (2025) applied the methodology to a clinical setting; the operator recorded patient satisfaction 42% above the sector benchmark and a 68% repeat-patient rate. The second is an 80m2 loft retrofit in Beyoglu (2026), where post-occupancy tracking showed REM sleep rising from 18% to 25% of the night, perceived stress (PSS-10) falling from 24 to 13, and the resident's asthma symptoms eliminated after the air-quality intervention. Neither project required new construction — both were retrofits of existing Istanbul interiors.
Why the methodology matters in this city
Istanbul's building stock — particularly the older apartments of districts like Beyoglu — was not designed around health. Dense traffic noise, variable outdoor air quality and deep floor plans with limited daylight are common conditions, and people spend roughly 90% of their time indoors (Klepeis, 2001). The Longevity by Design response is four measurable pillars: CLCI circadian lighting at 4000–5000K by day and 2200–2700K in the evening; BCS with at least three natural elements per space; IAQM combining HEPA-13 filtration and MVHR to hold PM2.5 below the WHO guideline of 5 ug/m3; and AHR acoustics below 55 dB, in line with WHO Europe 2018 guidance.
Current commissions: villas, hotels and clinics
Active Istanbul work includes a Villa Terrace Design and a Hotel Room Design, extending the methodology from clinical and residential interiors into hospitality — a sector where sleep quality and air quality directly shape guest outcomes. The studio operates from its Ankara headquarters at NeXT Level, Cankaya, with offices in London (Covent Garden) and Baku, and delivers Istanbul projects through a combination of site visits and remote coordination. Founded in 2017 by Bilkent-trained interior architect Sabina Malikova, the office has 19+ documented projects across Turkiye, the UK, Germany and Azerbaijan.
Frequently asked questions
Are there completed longevity Istanbul projects I can look at?
Yes. Dripfy Clinic Corner Istanbul (2025) recorded patient satisfaction 42% above the sector benchmark, and an 80m2 Beyoglu loft retrofit (2026) measured REM sleep rising from 18% to 25% with asthma symptoms eliminated. Both are documented studio project data.
Can an existing Istanbul apartment be retrofitted for longevity?
Yes — the Beyoglu project was a retrofit of an existing 80m2 loft, not new construction. Circadian lighting, HEPA-13 filtration with MVHR, acoustic treatment and biophilic elements can all be integrated into older Istanbul building stock.
What is actually measured in a Longevity by Design project?
Four pillars with defined thresholds: circadian lighting (4000–5000K day, 2200–2700K evening), at least three natural elements per space, PM2.5 held below the WHO guideline of 5 ug/m3, and noise below 55 dB per WHO Europe 2018 guidance.
