Luxury refurbishment in Berlin: features, costs and the neighbourhood conservation conflict

A luxury refurbishment is defined by the quality of its fittings and materials, rather than the extent of structural intervention: high-quality bathrooms, natural stone or solid wood parquet, designer taps, premium building services and smart home systems. In Berlin, this ambition encounters a particular constraint — luxury upgrades require permission in the 82 social conservation areas and are frequently prohibited. There is no credible flat rate per square metre for luxury refurbishments; costs have no upper limit. This guide explains what a luxury refurbishment involves, what is allowed in Berlin and what matters for your budget and contract.

Key points at a glance

• Luxury refurbishment = quality of fittings and materials, rather than extent of structural intervention — it can also be achieved without stripping out the building
• No credible €/sqm flat rate: costs have no upper limit; in our market assessment, the premium segment begins where complete refurbishment (Berlin 1.400–2.500 €/sqm) ends
• Berlin neighbourhood conservation conflict: luxury upgrades in social conservation areas require permission and are often refused (§ 172 BauGB)¹
• Not eligible for permission in Berlin: second WC/bathroom, elaborate bathroom refurbishment, opening up layouts, balcony/terrace over 4 m²²
• An independent quote review is particularly worthwhile for high contract values — flat rates per square metre reveal little

What makes a refurbishment luxurious?

The difference from a complete refurbishment or strip-out renovation lies in the quality, rather than the extent of structural intervention. A strip-out renovation strips the building back to its shell, but can use standard materials. A luxury refurbishment, by contrast, uses high-quality bathrooms, natural stone or solid wood parquet, designer taps, premium building services and smart home systems — and can be achieved without a complete strip-out. In Berlin, it is typical of grand period properties and Gründerzeit buildings, for example in Charlottenburg-Wilmersdorf, Grunewald or Mitte. Our overview introduces the different depths of renovation in House renovation in Berlin.

How much does a luxury refurbishment cost in Berlin?

There is no credible flat rate per square metre for a luxury refurbishment — the range has no upper limit and is determined by the quality of fittings and materials, rather than the extent of structural intervention. In our market assessment, the premium segment begins where complete refurbishment (1.400 to 2.500 euros per square metre in Berlin) ends. Anyone needing a reliable figure should have a specific, itemised quote reviewed instead of relying on flat rates — this makes a real difference with the high contract values involved in luxury refurbishment. An independent quote review reveals excessive prices and missing items before you sign.

The Berlin neighbourhood conservation conflict

In Berlin, luxury refurbishment encounters a legal boundary. In social conservation areas (Milieuschutz), measures may only be approved insofar as they provide the “contemporary standard of fittings of an average flat” (§ 172 para. 4 BauGB).¹ Anything beyond this is considered a luxury upgrade that may threaten the composition of the residential population — and is frequently prohibited. Berlin's district authorities maintain specific lists for this purpose.

The permission requirement also applies to measures that would otherwise not require a procedure under building regulations.² Before any high-specification work, therefore, clarify your address's conservation status with the district authority — this also applies to owner-occupiers. Find out more in our guide to Renovating an owner-occupied flat.

Luxury refurbishment of rental property

If you let the refurbished flat, only actual modernisation costs may be passed on: under § 559 BGB, this amounts to 8 per cent of the modernisation costs incurred for the flat per year. A cap of 3 euros per square metre over six years applies, reduced to just 2 euros where the initial rent is below 7 euros per square metre.³ Pure luxury upgrades are usually ineligible for permission in neighbourhood conservation areas anyway — the modernisation rent increase therefore only applies to the approved, “contemporary” portion.

Can I give my Berlin flat a luxury refurbishment in a neighbourhood conservation area?

Often you cannot. In social conservation areas, a luxury upgrade requires permission and is frequently prohibited (§ 172 para. 4 BauGB). District authorities only approve the contemporary standard of fittings of an average flat. Measures ineligible for permission include a second bathroom, elaborate bathroom refurbishment, opening up layouts or balconies over 4 m².

Which measures are considered luxury in Berlin and refused?

According to Berlin district authorities' approval criteria, these include unnecessary layout changes, merging or subdividing flats, installing a second WC, elaborate bathroom refurbishment and adding balconies, loggias or terraces with a floor area exceeding 4 m². First-time provision, such as installing a bathroom or central heating for the first time, and legally required energy efficiency measures remain eligible for permission.

What does a luxury refurbishment mean under tenancy law if I let the property?

For rented flats, only actual modernisation costs may be passed on: under § 559 BGB, 8 per cent of modernisation costs per year. A cap of 3 euros per square metre over six years applies (2 euros where the initial rent is below 7 euros).
