Looking for a building contractor in Berlin for your renovation? CARLO Design is an architecture, interior design and construction management studio in Berlin Mitte, and we take on the work between you and the firms: we select suitable firms, have them all quote on the same specification, prepare the contracts and lead the firms through to acceptance. You sign the contracts directly with the firms, and we remain your point of contact.
A contractor prices, builds and invoices. But who checks whether the quote is complete, whether what is built matches the drawings, and whether the invoice matches the work? That is the role we take on. We tender, compare, coordinate the firms and check quality and invoices, with no stake of our own in the construction.
Our Berlin studio in Mitte is led by Andrea Tomasena. With many carpenters, stuccateurs and parquet specialists we have worked for over a decade, in Wedding, Pankow and Lichtenberg. We know their work and their prices, and they know our drawings. So the choice comes down to more than the lowest price.
Whether a renovation goes well is largely decided before the first firm starts: in the selection, the quote and the contract.
We approach pre-qualified firms that suit the scope and standard of your project and assess them on price, scope and references. You get a clear comparison and our recommendation; the decision is yours.
Every firm prices the same description with quantities, materials and grades. You then compare figures for identical work rather than quote texts, and differences can be explained. We check for completeness first, then for the total.
How to compare quotesWe prepare the contracts, tie payments to verified progress and are on site every week. We flag deviations early and document variations with their effect on cost and schedule.
Construction management in BerlinThe problems in a quote usually lie in what it leaves out. We check every quote for that before we compare totals.
Usually it simply covers less work. What is missing returns as a variation once the screed is open and you can no longer compare.
What exactly gets built is then open to interpretation. We have such items broken down into single lines with quantities.
“Supply and lay tiles” covers everything from DIY-store stock to large formats. Quality and look remain open.
In a Berlin Altbau, substrate preparation and levelling are missing particularly often, along with dust protection, skips and hazardous waste.
For a renovation that is priced too roughly. The question then is: which drawings is the total based on?
A good quote states what is not included. If that line is missing, the limits of the contract are undefined.
Then four short questions. We reply within one working day, with no obligation. We speak English, German and Spanish.
Across our two studios, most of our new work comes through recommendations from past clients. 5.0 stars on Google, 5 reviews for our Berlin studio.
