A SafeUnit module stands where you already live: in the garden or beneath a new build. You start with one module for up to four people and extend later as your needs grow.
Space, cost and permits decide whether a shelter is an option at all.
One module needs roughly the footprint of a double garage. We check access for trailer and crane in advance.
You pay for one module, not for the final stage.
Above-ground garden shelters are often exempt depending on the state building code; underground units usually are not.
As storage, plant room or retreat. Protective operation is activated within minutes.
Plant-cast reinforced-concrete module with gas-tight blast door, NBC filter system and a prepared coupling point for later extensions.

SafeGarden Compact, SafeGarden Family and SafeOffice Premium differ in size, use and permit route. All three share the same reinforced-concrete core behind a ventilated timber facade.
Storage in everyday use, short-term refuge in an emergency.
Dimensioned for minimal procedure — geometrically compatible in 16 of 16 states, always subject to site review.
The middle ground: more space and technology, envelope volume deliberately below 30 m³.
Geometrically compatible in 12 of 16 states, shelter use and occupancy are reviewed separately.
Self-sufficient protected living and working space to the SafeOffice benchmark.
To be planned as a regular building project, with a pre-application or full permit from the outset.

| Transport mass | approx. 22–24 t | approx. 25–28 t | approx. 37–42 t |
Concept stage: sizes, masses and fit-out are initial assumptions. Any protective effect applies only after a defined load and test profile and site-specific verification. Dimensioned for exemption does not mean permit-free everywhere — development plan, boundary distances and actual use always have to be checked.
From the first site review to handover — every step with a fixed point of contact.
We check footprint, subsoil, access and permit situation.
Occupancy, installation variant and equipment, matched to your budget.
Prepare the foundation, set the module by crane — typically within one day.
Power, ventilation and backup supply connected, grounds restored.
Filter system function test and briefing for the whole family.
Maintenance intervals, filter changes and a contact for the years ahead.
What matters legally, fiscally and in terms of funding before construction starts.
Whether an above-ground unit is exempt depends on the state building code. We supply reviewable documents.
Grants for burglary protection can in many cases be applied to doors, airlocks and security technology.
For rented or commercially used properties, increased depreciation may be available.

You can take on earthworks and landscaping. Foundation, placement and technical connection are done by us.
Send us your site and the planned number of people — you get a concept outline in return.
We review site, requirement and permit situation. Every project is treated confidentially — without naming references, if you prefer.
