Before You Apply: What to Prepare
Good preparation starts with useful records and the right questions. What should you clarify before preparing a permit application?

Start with your plans, not the paperwork
Before you start collecting drawings and formal statements, try describing your plans in a few everyday sentences. Do you want to add a room, turn an attic into living space, or build a house on an empty plot? Write down the intended result, who will use the space, and what you cannot do without. Include anything you are still unsure about. For an initial conversation with an architect, this overview is often more useful than a folder of images without context. It helps separate essential needs from wishes that can wait. The preparation and any approval process depend on the particular proposal and location. Treat a friend’s experience as a source of questions rather than a set of instructions that will necessarily work for you.
Gather what you already know about the site
Start by gathering the plot details, available ownership information, older drawings, previous permits, and photographs of the current condition. For an existing house, records of alterations are useful too, if you have them. You do not need to obtain everything in advance. What matters is knowing what exists, where each document came from, and whether it reflects reality. An old plan may show a doorway that disappeared years ago or leave out a later extension. The architect can then recommend a measured survey or further investigation where missing information could affect the design. Keep the documents in one place and label them with their date and source. Even a simple list marked ‘to be checked’ makes the next steps easier and helps avoid basing the design on outdated information.
Check the site before the design takes shape
An attractive floor plan does not yet tell you whether the proposed building makes sense on its site. Early checks should cover the local land-use plan, access to the plot, options for utility connections, and any restrictions, such as heritage protection or flood risk. The exact scope depends on the location and the proposed work. For an extension, the position of neighbouring windows may matter; for a house on a slope, changes to the terrain and rainwater management may be important. This is not about finding reasons why something cannot happen. It is about spotting factors that could change the building’s size, position, or technical design while revisions are still straightforward. Where something is unclear, prepare a specific question and supporting documents for a consultation with the relevant authority or utility operator.
Agree on a clear next step
After the initial checks, the main thing you should have is a clear overview: what you know, what is missing, who will find it out, and which tasks depend on others. Agree with your architect who will obtain each document, arrange any specialists needed, and communicate with the authorities. Designing the project and handling the application are not automatically the same service, so it is worth explicitly agreeing on the scope of the appointment. Documentation requirements and the procedure need to be checked against current Czech rules and the specific circumstances of your project. Neither an initial consultation nor a carefully assembled folder guarantees approval or a particular completion date. Even so, they are valuable: they help reveal unresolved questions before the whole design rests on an unchecked assumption. End the meeting by writing a short list of the next tasks.
