House renovation in Berlin: costs, sequence and funding in 2026

A complete house renovation in Berlin costs between 1.400 and 2.500 euros per square metre of living space, depending on the building's condition and scope of work. For a typical Berlin terraced or detached house of around 130 square metres, that equals 182.000 to 325.000 euros before funding. Modernising individual trades alone starts significantly lower. Prices for maintenance work on residential buildings recently rose by 4,1 per cent year on year¹ — measured by the Federal Statistical Office's construction price index (base 2021 = 100).² This guide shows what costs to expect, the right order of work, which funding applies in 2026 and what matters when dealing with Berlin's building stock.

Key points at a glance

• Complete house renovation in Berlin: 1.400–2.500 €/sqm — around 182.000 to 325.000 € for a 130-sqm house before funding
• Sequence: first check hazardous materials and structural integrity, then the building envelope (roof, façade, windows), then building services, and finally the interior fit-out — for energy efficiency, insulate first, then replace the heating
• 2026 funding: KfW heating grants up to 70 %, BAFA building envelope grants 15 % (+5 % with a renovation roadmap), plus Berlin's IBB programmes — always apply before awarding the contract
• When replacing heating in Berlin, the 65-% renewable energy requirement applies once the municipal heat plan is available, and no later than 30.06.2026⁵
• Around 72 % of project owners exceed their budget (Almondia/FAU Erlangen, 2017)¹⁴ — allow a contingency of 10 to 15 %, and more for older buildings

What does a house renovation cost in Berlin?

Total costs depend mainly on how deeply the work affects the building fabric. A cosmetic refresh is a different project from a full strip-out renovation, in which the house is stripped back to the shell and rebuilt completely. Based on our market experience, Berlin is 10 to 25 per cent above the national average — the premium is highest for labour-intensive trades and lower for material-intensive ones (windows, heating). The following table gives a guide for a house with around 130 square metres of living space:

The terms are often mixed up in everyday usage. A complete renovation modernises all trades but leaves the load-bearing structure untouched. A strip-out renovation goes further: the building is stripped back to its shell (external walls, floor structures and, where applicable, roof timbers) and rebuilt — the most invasive and expensive option. We cover the special case of renovating older buildings in Berlin with Gründerzeit-era fabric, hazardous materials and heritage protection in detail in a separate guide. A breakdown of national average costs by trade is available under Renovation costs 2026.

In what order should you renovate a house?

A house renovation involves two sequences that apply in parallel and should not be confused: the construction sequence of trades and the energy efficiency sequence of measures. Following both avoids expensive repeated work and oversized equipment.

Construction sequence: outside to inside

The practical logic runs from the building fabric to the interior fit-out:

1. Assess the existing building: Hazardous materials analysis (asbestos, PAHs, tar felt) and a structural check come first — they determine everything that follows. For buildings from before 1990, hazardous materials testing (300–800 euros) is strongly recommended.
2. Building envelope: Roof, façade and windows. Only once the house is weatherproof and insulated can the heating load and building services be sized correctly.
3. Building services: Electrics, plumbing, heating. These trades are installed while walls and floors are still open.
4. Interior fit-out: Screed, plaster, bathrooms, floors, painting and kitchen last.

Energy sequence: insulate first, then heat

From an energy perspective, the rule is clear: insulate the building envelope first, then renew the heating. Replacing the heating before insulating means sizing it for the poor existing condition — after insulation, it is oversized, runs inefficiently and consumes unnecessary energy. The consumer advice centre therefore recommends coordinating the measures through an individual renovation roadmap (iSFP).⁴ The iSFP also brings an additional funding bonus of 5 per cent for BAFA individual measures (see below).

How long does a house renovation take in Berlin?

Allow six to twelve months for a complete house renovation; a standard renovation involving individual trades can be done in two to four months. For Berlin schedules, lead times matter more than the work itself: in-demand trades such as plumbing/heating and electrical work often have waits of 4 to 12 weeks in Berlin, or three to four months in peak season. If heritage protection is involved, approval from the district office alone takes another 4 to 12 weeks.

What funding is available for house renovation in Berlin in 2026?

Federal and state funding can be combined for energy measures. The most important rule first: the funding application must be submitted before awarding the contract . Signing the quote first and applying afterwards forfeits your entitlement.

KfW: heating and Efficiency House

The KfW heating grant (programme 458) supports replacement with climate-friendly heating with basic funding of 30 per cent. Added to this are a climate speed bonus of 20 per cent (for early replacement of old oil or coal heating, or gas heating at least 20 years old), an income bonus of 30 per cent (for taxable household income up to 40.000 euros) and an efficiency bonus of 5 per cent for certain heat pumps. A maximum of 70 per cent is available overall; for a detached house, eligible costs are capped at 30.000 euros for the first housing unit.⁷ For comprehensive energy renovation to Efficiency House standard, the residential building loan (programme 261) offers up to 150.000 euros per housing unit and a repayment grant.⁹

BAFA: individual building envelope measures

BAFA funds individual building envelope measures — façade, roof and basement ceiling insulation, plus window replacement — with 15 per cent of eligible costs, plus a 5 per cent bonus if the measure forms part of an individual renovation roadmap.⁸ Read more about insulation costs in our guide to façade insulation.

Tax incentive and listed building depreciation

Owners who do not use KfW/BAFA funding can claim tax relief on energy measures in an owner-occupied house more than ten years old under § 35c EStG: 20 per cent of the costs over three years, up to a maximum of 40.000 euros.¹⁰ Listed building depreciation is particularly attractive for Berlin's many listed buildings: for rented properties, § 7i EStG allows 100 per cent of eligible renovation costs to be deducted over twelve years (9 per cent annually for the first eight years, 7 per cent for the following four); for owner-occupation, § 10f EStG allows 90 per cent over ten years.¹¹ Coordination with the local heritage authority is required. Important: § 35c and listed building depreciation cannot be combined with KfW/BAFA funding for the same measure.

IBB: Berlin state programmes

Investitionsbank Berlin (IBB) supplements federal funding with state programmes such as “Effiziente GebäudePLUS” — low-interest loans for energy renovation that can be combined with KfW programmes, provided funding caps are respected.¹² Terms change regularly — check the current details directly with IBB.

What does the GEG require for renovation in Berlin?

The Buildings Energy Act (GEG) sets specific requirements for house renovation. When heating is replaced, new systems must operate on at least 65 per cent renewable energy. In large cities such as Berlin (over 100.000 inhabitants), this obligation applies once municipal heat planning is available — no later than 30 June 2026.⁵ Transitional arrangements are possible until then. The 65 per cent requirement only takes effect with the official announcement of Berlin's heat plan, rather than automatically on the cut-off date.

The GEG also requires certain minimum energy standards during renovation once more than 10 per cent of a component's area is renewed (de minimis threshold). For example, if the façade is re-rendered and insulated, the external wall must afterwards achieve a heat transfer coefficient no higher than 0,24 W/(m²·K), and new windows no higher than 1,3 W/(m²·K).⁶ These values also matter when assessing quotes: a quote that does not meet GEG requirements leads to expensive remedial work later.

Special considerations for house renovation in Berlin

Berlin's housing stock is old and dense: the 2022 census counted around 2,04 million homes in approximately 336.000 residential buildings.³ A substantial proportion dates from the pre-war and post-war periods — with corresponding renovation requirements. Berlin is also Germany's most pronounced city of tenants: its homeownership rate is only around 16 per cent, the lowest of all federal states.¹⁶ Renovations here therefore particularly often involve homeowners' associations — the rules are explained in our guide to WEG renovation.

Which building type characterises each district?

“Berlin” is not a single renovation market — the cost range depends heavily on building type, which is broadly distributed by location. Three patterns shape the city:

Practical consequence: in Gründerzeit neighbourhoods, checking listed status and neighbourhood protection is decisive before every measure; on large estates, quotes are easier to compare because construction is standardised — inflated lump sums stand out sooner.

Three cost drivers in Berlin's existing buildings

Across all locations, three factors regularly push costs above national levels:

• Heritage and neighbourhood protection: Berlin's list of protected monuments contains around 12.000 entries, about 70 per cent of which are listed buildings — one entry may cover many individual addresses.¹³ There are also 82 social conservation areas (neighbourhood protection) where layout changes, combining flats, a second bathroom or underfloor heating require approval and are often refused.¹⁵ External insulation on listed façades is usually not approved; alternatives such as internal insulation cost more.
• Hazardous materials in the fabric: Asbestos, PAHs and tar felt are common in buildings from the 1950s to 1980s and add costs of 30 to 120 euros per square metre.
• Old building services: Aluminium wiring, lead pipes and outdated gas boilers must be renewed during renovation — items often missing from quotes and leading to variations .

Our detailed guide covers Gründerzeit fabric, hazardous materials checks and heritage protection in more depth: renovating older buildings in Berlin. For a broader overview of Berlin's construction market, including new builds, see our guide Building and renovating in Berlin.

Which company should carry out the house renovation?

There are two routes for a house renovation: award separate contracts to specialist companies, or appoint a main contractor to coordinate all trades. Separate contracts are usually cheaper but require coordination and site management; a main contractor handles this for you and charges a coordination premium. The worthwhile option depends on scope, time and your experience. Our guide shows how to find and compare reputable renovation companies in Berlin: guide to choosing a company.

Whichever route you take, obtain several quotes and compare them systematically. With Berlin contract values often above 150.000 euros, a careful review before awarding the work is crucial — our guide explains how to make quotes comparable: Comparing contractors' quotes. In our reviewing experience, the items most often missing from Berlin renovation quotes are disposal, scaffolding, hazardous materials handling and site setup. If you have a specific quote, an independent quote review can reveal inflated prices and missing items before you sign.

Frequently asked questions

What does a complete house renovation cost in Berlin?

A complete house renovation in Berlin costs 1.400 to 2.500 euros per square metre. For a 130-sqm house, that is 182.000 to 325.000 euros before funding. Standard renovation involving individual trades costs 800 to 1.400 euros per square metre, and cosmetic refurbishment 300 to 600 euros. Berlin is 10 to 25 per cent above the national average.

In what order should a house be renovated?

For construction: first check hazardous materials and structural integrity, then the building envelope (roof, façade, windows), then building services (electrics, plumbing, heating), and finally the interior fit-out. For energy efficiency, also insulate first, then replace the heating — otherwise the heating will be oversized and run inefficiently. An individual renovation roadmap (iSFP) coordinates both sequences.

How long does a house renovation take in Berlin?

A complete house renovation takes 8 to 14 months including planning, approvals and contractor lead times; standard renovation of individual trades takes 4 to 8 months. The actual construction time is shorter; in Berlin, trade lead times (4 to 12 weeks) and heritage approval (another 4 to 12 weeks) are decisive.

What funding is available for house renovation in Berlin in 2026?

The KfW heating grant (458) supports climate-friendly heating with up to 70 per cent (eligible cost cap of 30.000 euros for a detached house). BAFA funds building envelope measures with 15 per cent (plus 5 per cent with a renovation roadmap). Other options include KfW residential building loan 261, the tax incentive under § 35c EStG, listed building depreciation and Berlin's IBB programmes. Always apply before awarding the contract.

Must I convert the heating to 65 per cent renewable energy when renovating in Berlin?

Yes, as soon as you replace the heating. The GEG's 65 per cent renewable energy requirement applies in Berlin when municipal heat planning is announced, no later than 30 June 2026. Anyone installing new heating beforehand can use transitional arrangements. You do not have to replace an existing, working heating system solely because of the renovation.
