Construction management,
so the design survives the build.

Construction management for private houses, apartments and fincas in Berlin and on Mallorca, and for restaurants and hotels: tendering, trade coordination, scheduling, quality control and budget tracking through to handover. We run our own designs and external plans, in Germany under HOAI work stage 8, on Mallorca with local aparejadores and authorities. You receive weekly reports, whether or not you are on site.

What we do

Most homes are not lost in design.
They are lost on site.

A beautiful concept survives only if someone is there, every week, making sure it gets built that way. That is what construction management is for. We coordinate trades, check work, manage schedules, control budgets, and stand between your design and every shortcut someone is tempted to take.

We work on our own projects and as construction managers for outside designs. In Germany our scope follows HOAI Leistungsphase 8. On Mallorca we coordinate with the local aparejador and keep the whole build moving in one direction, yours.

The phases

Construction management in five phases, from kickoff to keys.

Construction management is the longest phase of any project. For a full renovation the construction phase starts at four to six months and can run longer. We are on site every week, and reachable every day.

i.
Tender & Trade Selection
We prepare detailed tender packages, collect bids from pre-qualified trades, and evaluate them on price, scope and track record. You get a clear comparison and our recommendation, and you make the call.
ii.
Schedule & Budget Setup
Master schedule, milestone plan, and a payment schedule tied to verified progress, not invoice dates. Trades know what is expected, when, and at what quality. So do you.
iii.
Site Supervision
Weekly site visits with written reports. We check what was built against what was drawn, flag deviations early, and resolve detail questions before they become rework. Photo documentation of every phase, every layer.
iv.
Coordination & Change Management
Construction always surfaces decisions no one anticipated. We coordinate between trades, manage requested changes, document cost and schedule impact, and keep the design intent intact through every revision.
v.
Handover & Defects Period
Final walkthrough, defects list, sign-off. We hand over a complete documentation package, as-built drawings, manuals, warranties, and stay involved through the legal defects period, so anything that surfaces gets resolved.

Construction management in Berlin and on Mallorca.

Two regulatory environments, two construction cultures. We know the German Bauordnung and the Spanish Ley de Ordenación de la Edificación, and we work with trade networks established over a decade in both markets.

FAQ

Common questions about construction management.

A general contractor builds and sells you the result; construction management represents you towards the trades. We tender, compare bids, coordinate the firms, check quality and invoices, and have no stake of our own in the execution. You contract directly with the trades.
Tendering and trade selection, schedule and budget setup, weekly site supervision with reports and photos, coordination and change management, handover with defects list and warranty documentation. In Germany this corresponds to HOAI work stage 8; on Mallorca we work with the aparejador and the authorities.
Yes. We run our own projects and plans by other offices, for houses, apartments and fincas as well as restaurants and hotels. The prerequisite is a set of execution drawings that can be tendered cleanly; if it is missing, we complete it.
For a full renovation the construction phase starts at four to six months and can run longer; a whole-house project including planning typically takes 6 to 12 months. Speed depends on trades, consent and budget, and some firms work faster at a higher price.
Yes, on Mallorca that is the normal case. We are on site every week, you receive reports with photos and decision papers, and every acceptance is documented. You travel for the appointments where your presence counts.
We discuss fees in the Project Check based on scope, construction sum and duration. We tell you in advance which services are included and what the trades themselves charge.
With the Project Check. Send us your drawings, timeline and budget; we tell you honestly what is feasible, what we would do differently and what the execution demands.
