Why investors choose MonArch
We work so that the building site holds no surprises — neither in the design nor in the budget.
Licensed architects
Every design is signed by an architect with unrestricted design qualifications, registered with the Polish Chamber of Architects.
Fixed price in the contract
Scope, price and deadline are written into the contract. Revisions within the agreed scope are free.
Permit-ready documentation
Drawings meet the Building Act and technical conditions, so the office does not send the application back.
Low running costs
Designed to WT2021: solar analysis, thermal bridges, ready for a heat pump and photovoltaics.
Support until the build ends
We answer questions from your contractor and the authorities long after handover.
Four working languages
We run projects in Polish, English, Ukrainian and Russian — remotely if needed.

Recent projects
Houses built from our designs.
What investors say
Collected after the projects were handed over.
We were afraid the architect would impose his own vision. The opposite happened — we got three concept options and, with each one, an honest account of what would be expensive to build. The house has stood for a year and we would not change a thing.
Marta i Paweł Kowalscy
Private clients, Konstancin
The zoning conditions on my plot were absurdly restrictive. Two other studios turned me down. Here I was told it could be done, and it was — with no appeals and no delays at the planning office.
Tomasz Wiśniewski
Client, Zielonki
All communication was in Ukrainian, which mattered enormously to me given Polish building regulations. I received a translation of every letter from the authorities along with an explanation of what it actually meant.
Olena Kravchenko
Client, Warsaw
Author supervision looked like an unnecessary cost until the contractor proposed changing the floor slab structure "because it will be cheaper". One visit from the architect saved me a problem that would only have surfaced years later.
Jakub Zieliński
Client, Mikołajki
Extending an old house is a harder brief than building from scratch, and many studios will not take it on. Here I got a design that does not pretend the extension was always there, yet the whole still reads as one building.
Anna Nowak
Client, Poznań
I bought a catalogue design and only needed the adaptation. They completed it in nineteen days, including a change to the upper floor layout and an added garage. The price never moved a single złoty from the initial quote.

From our blog
Practical guidance on building, paperwork and costs.
Polish building law
Zoning decision or local plan — which applies to your plot
Which document applies determines how long the formalities take and whether the house you have in mind can be built on that plot at all.

What building a house in Poland actually costs
Cost per square metre is the most misleading budgeting tool there is. We break the cost down by stage so you can see where the money actually goes.

Tips
Single-storey or with an attic — choosing without regret
This choice affects the plot price, the build cost, the bills and how comfortable the house will be in thirty years. There is no universally better answer.

Frequently asked questions
Did not find your answer? Write to us — we reply the same working day.
How long does it take to prepare a house design?
Concept — 5–10 working days. Interior layout — 7–14 days. Adaptation of a stock design — 14–30 days. A full custom design — 30–60 working days. We count from contract signature and deposit; rush delivery shortens these by roughly 40 percent for a 30 percent surcharge.
What does the payment schedule look like?
Payment is split into three instalments: a 30 percent deposit on signing, 40 percent once the concept is approved, and 30 percent on handover of the complete documentation. We accept bank transfer, BLIK, Visa and Mastercard, Apple Pay, Google Pay, and cash on signing.
Can the price go up during the project?
No. The contract amount is fixed. It can only increase if you commission changes beyond the agreed brief — and in that case we present a quote first and wait for your approval. Revisions within the agreed scope are free of charge.
Do I need to own the plot before ordering a design?
For a full custom design — yes, because we design around the specific zoning conditions, sunlight and access. For a concept or a consultation — no. Many clients come to us exactly while choosing a plot, to check whether what they have in mind can be built on it.
What exactly is included in the building permit documentation?
The site development plan, the architectural and construction design, the technical design including structure, plumbing and electrical services, the energy performance certificate, and the required designer declarations and licences. We supply four printed sets and a complete set of PDFs as standard.
How many revisions can I request without extra cost?
We do not cap the number of revisions — we cap their scope. Anything within the approved brief is revised free of charge as many times as needed. Only changes that alter the brief itself are chargeable, for example adding a storey after the concept has been signed off.
