Renovation & refurbishment · Berlin & surroundings
From bathroom refurbishment to complete apartment and period-building renovation: we bring existing properties up to today's structural, visual and energy standards.
What this is about
Berlin is a city of existing buildings: Gründerzeit apartment houses, post-war blocks, prefab estates, young condominiums – every fabric follows its own rules. A good renovation therefore starts not with demolition but with understanding: What is load-bearing? What deserves protection? Where are moisture, services, legacy materials?
CAVCON renovates apartments, houses and commercial spaces in Berlin with a structured build sequence: survey and fixed-price offer first, then strip-out, first-fix installations, fit-out and finishes – coordinated by one contact who keeps all trades aligned.
That we know how to treat existing fabric with care is shown by projects like the Stadtpalais Nassau (listed building fabric) and the renovation of the WÖH12 steam-bread bakery, where ongoing operations and hygiene requirements set the pace.
Our standard
No surprises: we name the risks in the existing fabric honestly before work starts, calculate transparently, and call you before something gets more expensive – not afterwards.
Scope of services
Complete bathroom renovation: strip-out, waterproofing, pre-wall installation, tiling, sanitary fitting – level-access showers included.
Whole apartments before moving in or re-letting: floors, walls, coordination of electrics and plumbing, doors, decoration – turnkey.
Gründerzeit and listed buildings: we modernise with a light touch – respecting stucco, floorboards and proportions, in dialogue with the relevant authorities.
Insulation, window junction upgrades, facades (external wall insulation): measures that cut heating costs – coordinated rather than patched together.
Shops, hospitality, practices: renovation under time pressure, sometimes during ongoing operation – with a firm construction schedule.
After water damage or wear: we restore the fabric professionally, from drying through to the new finish.
Quality & workmanship
Everything starts with the on-site survey: we assess fabric, moisture and service routes, clarify wishes and budget, and define the scope in writing. You receive a fixed-price offer with clear line items – no 'approximate' sums that grow on site.
Execution follows a fixed order: protection and strip-out, first fix, drywall and screed, waterproofing and tiling, finishes and final fit. Drying times are respected, not argued away. At the end we walk through the result together and hand over the documentation – including the records landlords and building management want to see.

Frequently asked questions
The range is wide and depends on condition, area and specification – redecorating with new finishes costs a fraction of a full core renovation with new electrics and bathrooms. It can only be quoted seriously after a site visit; our initial consultation and fixed-price offer are free.
Yes. At the Stadtpalais Nassau we renovated and fitted out listed building fabric. We work with reversible, fabric-friendly solutions and coordinate measures with the relevant authorities.
For partial renovations (e.g. bathroom only) usually yes – we work in sections and keep dust control and site hours disciplined. For core renovations we recommend moving out temporarily; we discuss this honestly up front.
A bathroom typically takes two to four weeks; a complete apartment from several weeks to a few months depending on scope. Your quote includes a schedule with realistic buffers – and we tell you when something shifts, not on handover day.
Yes. As the main contractor we coordinate the specialist trades involved and take responsibility for the overall sequence – you have one conversation with us instead of five with individual firms.
