Office-to-Coliving Conversion in Cloche d'Or: Capturing 5.5% Yield in 2026

A New Era for Real Estate Investment in Cloche d'Or

The Cloche d'Or district, the fast-evolving economic heart of Luxembourg City, is becoming the prime location for a new asset strategy: converting office spaces into premium coliving units. This trend is accelerating under the impetus of the 2026 Budget Law, published in the official gazette on December 19, 2025 [2].

With an attractive target yield of 5.5%, these projects now benefit from an optimized tax framework, particularly due to accelerated depreciation measures designed to encourage the energy renovation of rental housing.

The 10% Accelerated Depreciation: A Profitability Lever

The major innovation for investors lies in the amendment of Article 106 of the Income Tax Law (LIR). A Grand-Ducal Regulation adopted in early 2026 increased the accelerated depreciation rate for investment expenses related to sustainable energy renovations of rental dwellings from 6% to 10% [1].

This measure, effective from the 2026 tax year, allows owners to deduct renovation costs much faster when computing taxable rental income [1]. In the context of a "office-to-coliving" conversion in Gasperich or Cloche d'Or, this tax acceleration mechanically boosts the immediate net yield.

Eligibility Criteria

To capture the 10% rate, the works must:

Involve sustainable energy renovations benefiting from government subsidies under the Law of December 23, 2016 [1].
Aim to improve the energy efficiency of the building.
Be carried out on dwellings intended for rental [1].

Why Premium Coliving in Cloche d'Or?

The Luxembourg rental market remains under pressure, and demand for flexible "all-inclusive" solutions is skyrocketing. The 2026 budget confirms the government's commitment to supporting the country's attractiveness despite moderate economic growth [4].

Cloche d'Or, home to the headquarters of major banks and consulting firms (PwC, Deloitte), provides a pool of high-end tenants. Coliving maximizes rental density while offering premium services, justifying higher total rents than traditional leases. Investors also benefit from the inflation update of revaluation coefficients for determining capital gains on real estate, as provided in the 2026 Budget [2].

A Comprehensive Tax Strategy for 2026

Beyond real estate, the 2026 Budget Law introduces several measures that strengthen the purchasing power and investment capacity of residents:

CO2 Tax Credit: This increases from EUR 192 to EUR 216 for low-income earners, offsetting the EUR 5 per tonne carbon tax hike [2][3][5].
Pension Savings: The annual deduction ceiling for third-pillar contributions rises to EUR 4,500 (up from EUR 3,200) [4].
Start-up Investment: A new 20% tax credit (capped at EUR 100,000) has been established to encourage investment in innovative companies less than five years old [4][6].

By combining these advantages with the profitability of coliving, institutional and private investors can structure resilient portfolios in the face of inflation.
