Sweden's building stock is old, and its owners are disciplined about it. A large share of the country's multi-family housing was built during the Miljonprogrammet era of the 1960s and 70s, and much of it is now approaching or past the point where major systems, building envelopes, and energy performance need a second life. Swedish fastighetsbolag and pension-linked property vehicles have spent the past decade refining how they scope, budget, and execute renovation and retrofit programs at scale. That discipline travels well, and it is increasingly being applied to a second, less obvious portfolio: Turkish assets acquired for yield, for family use, or as part of a wider Mediterranean diversification strategy.
Why renovation economics look different in Türkiye
A Swedish investor who has run retrofit programs at home arrives in Türkiye with good instincts and a few false assumptions. The good instincts: sequence structural and envelope work before finishes, treat mechanical and electrical upgrades as inseparable from energy performance, and never sign a scope of work without a line-item cost breakdown. The false assumption is usually about labor and material cost ratios. In Sweden, labor typically dominates a renovation budget. In Türkiye, materials and finishes often carry a larger share of total cost, particularly for imported fittings, elevators, and higher-spec glazing. This changes how value engineering should be approached: a Swedish-trained renovation manager who reflexively cuts labor hours to control cost will miss the larger savings available in material sourcing and specification.
Structural context : Türkiye's building code, updated after the 1999 and more recently the 2023 earthquakes, places real weight on seismic retrofit for older structures. Any renovation or repositioning project involving a pre-2000 building should start with a structural assessment, not a design brief. This is not optional due diligence, it determines whether a project is a renovation at all or effectively a rebuild.
Where retrofit demand is concentrated
Three segments account for most of the renovation and retrofit activity relevant to Swedish capital:
Coastal residential stock : Properties along the Aegean and Mediterranean coasts built in the 1990s and 2000s are being acquired and upgraded for the short-let and long-stay rental market. The scope is usually envelope insulation, mechanical system replacement, and interior modernization rather than structural work, since these buildings are newer.
Istanbul mixed-use and office assets : Older office and mixed-use buildings in central Istanbul districts are candidates for energy retrofit and repositioning as tenants increasingly demand certified, efficient space. This is the segment most analogous to what a Swedish institutional investor already does at home.
Urban transformation parcels : Türkiye's kentsel dönüşüm framework creates opportunities to acquire older buildings for full reconstruction rather than renovation. This is a different risk profile, more development than retrofit, and should be underwritten separately.
Contractor and scope discipline
The retrofit contractor market in Türkiye is fragmented, and quality varies more widely than in Sweden's more consolidated construction sector. For any renovation above a modest scale, a Swedish buyer should insist on:
- A fixed-price contract with clearly itemized material specifications, not allowances - Independent verification of structural assessments before signing off on scope - A payment schedule tied to inspected milestones, not calendar dates - Energy performance targets written into the contract, with measurement, not aspiration
Sequencing : Structural and seismic work first, envelope and building systems second, interior finishes last. Projects that reverse this order, chasing a fast-looking finish before the building's bones are addressed, tend to run over budget and over schedule.
A practical starting point
For a Swedish investor evaluating a renovation-driven acquisition, the useful first step is not a design consultation but an independent structural and cost audit of the target property, conducted before terms are finalized. That audit should price seismic retrofit, envelope upgrade, and mechanical replacement as separate line items, since each carries a different cost curve and a different payback horizon. Treating renovation in Türkiye as a scaled-up version of a Swedish retrofit program is a reasonable starting instinct. Getting the cost structure and sequencing right is what separates a well-executed project from a costly one.
