f immobilien ag is an owner-run real estate company from Wolfhalden in the Appenzell region. We sell houses, apartments and land, as well as commercial and industrial properties, hotels and restaurants – personally, honestly and with an eye for detail.
And we don’t just sell – we build. As the agency for Fullwood Wohnblockhaus we have planned and built solid-wood homes all across Eastern Switzerland, from the plot to the handover. The houses shown above were built by us. Our own show house in Wolfhalden has stood since 2015.
Every property receives a professional dossier, well-thought-out marketing and support that ends only once everything is done and dusted.
Licensed in the Canton of Ticino as a fiduciario immobiliare (real estate fiduciary) — registered with the Autorità di vigilanza sull’esercizio delle professioni di fiduciario, Bellinzona, since 2022, verifiable in the online register. So we can support you with legal certainty in Ticino as well.


Every property with a detailed dossier – just ask us.
House, apartment or land – personally guided, throughout Switzerland
Thinking of selling your property? We guide you from the first conversation to the notarised deed – with a realistic valuation, professional marketing and a discreet network. A first estimate is free of obligation; one call is enough.
More about selling
We don’t just broker — we build, too.
As the agency for Fullwood Wohnblockhaus we guide you from the plot through planning to the finished house in solid wood — healthy, durable and pleasantly warm.
We built our show house in Wolfhalden ourselves. Come by and experience solid wood with all your senses — just arrange an appointment.
Built fairly – that’s why the relationship lasts. For the timber construction up to the weathertight shell we guarantee you a fixed price depending on the variant. All further budget items we work out together with you and bill them directly and transparently. The result is a fair build with no hidden costs – and that is exactly why we still have a good relationship with all our clients to this day.

A Fullwood house is built single-shell from solid timber — one single, continuous wall without insulation layers, films or composite materials. The wood absorbs moisture and releases it again. The result is a balanced, pleasant indoor climate you feel from the very first step.
Add to that the thermal mass of the wood: the solid walls absorb heat and release it slowly back into the room. In winter the warmth stays in the house; in summer the rooms heat up far less. That keeps energy demand low — and the temperature steady throughout the day.



Building land has become scarce — and that is exactly where our work begins. We help you search and show you paths you might not think of first: plots not yet on the market, demolition properties with potential, building rights, replacement new-builds or splitting an oversized plot.
We check the plot for you — before you commit:
Zone, plot ratio and building regulations · boundary distances and possible development · servicing and connections · slope, subsoil and access · easements and encumbrances in the land register · realistic construction costs and the approval path.
We work with specially developed software and plan for you, from the single-family home to an entire development.
Photos no longer exist for every earlier house — less was documented back then.
What we do for you.
Houses, apartments and land – as well as commercial and industrial properties, hotels and restaurants. In Eastern Switzerland, in Ticino and beyond.
We find building land you wouldn’t think of first – quiet plots, demolition properties with potential, building rights, replacement new-builds and the splitting of oversized plots. And we check the plot before you commit.
In-house planning – from the feasibility study to the building application. First the law checked, then the plan: site, floor plans, sections and elevations to standard.
Houses in solid timber as the agency for Fullwood Wohnblockhaus – with our own show house in Wolfhalden. Thanks to building directly, we still have a good relationship with all our clients to this day.
We run your building project, obtain tenders, award the works and safeguard your interests towards the contractors.
Professional dossiers, online marketing on the major portals and discreet network marketing.
We calculate the realistic market price with our own software – from real regional sales data, not from gut feeling.

Is it worth it? Feasibility, volume, rough costs compared.
The concept: positioning on the site, floor plans, proof of building rights, cost estimate.
Worked-out plans, construction description, cost estimate.
Approval-ready plans and the building application – the path to the permit.
Working drawings, tenders and site management – through to the finished, move-in-ready house.
