Let's talk
about your plot
The first conversation commits you to nothing and takes about fifteen minutes. We will ask about the plot, the budget and the timing — and tell you honestly whether it is realistic.
How to reach us
Phone
+358 9 4520 180
Mon–Sat 9:00–18:00 Finnish time.
build@longhouse.fi
We reply within one working day. Send the property ID and we will attach a shortlist.
Messaging
If you would rather not talk, write instead. It is usually quicker: we send budgets, site photographs and floor plans straight into the chat.
Meeting in person
At the Helsinki office or in the layout pavilion. Mill tours run every Wednesday at 11:00.
An easy first step
A free estimate
of the cost
Tell us in a couple of lines what you want to build. In return we will send a budget for the series that fits, broken down by stage, along with the timing and a list of what the price does not cover — so there are no surprises later.
- An answer within one working day
- No “just checking in” calls
- You can walk away at any stage with no penalty
