With a vaulted ceiling, acoustic-friendly rendered walls and a kitchen island benchtop that wheels away, Emma Jardine and Benjamin Kopp can transform their Wentworth Falls home into the perfect chamber music venue.
Which is exactly what they will do this Sunday, presenting an intimate concert of Beethoven, Schubert and Arensky with Sydney Symphony principal cellist, Umberto Clerici.
Creating the purpose-built room has fulfilled a long dream for the couple.
"We lived in Europe for eight years, in Geneva and Berlin, right in the middle of the city," said Ms Jardine, a violinist.
"We came back to Australia three times a year to perform and every time we were blown away by the natural beauty here."
So when their move home was to become permanent, they built their eco home from straw bales. The whole house uses passive solar design, meaning the music room is flooded with sun in winter but remains cool in summer.
The music room itself replicates the exact dimensions of one Sir Arthur Streeton (after whom the group is named) built for his violinist wife, Esther.
The trio held its first concert in the space last November, seating 90 people.
Mr Kopp, a pianist, said they had been a bit nervous before the first show, wondering if anyone would come, but they ended up with a full house.
The trio performed against the backdrop of views out to the national park and the audience were in enthusiastic agreement that the room provided flawless acoustics.
Many also commented on how right it felt to enjoy chamber works in the kind of space for which they were written.
Mr Kopp said: "Chamber music was composed for just this kind of intimate home setting. It's a real joy to play with that kind of atmosphere."
Last year's audience were eager for the trio to consider making the house concerts a recurring feature of the Blue Mountains music calendar and this second performance will no doubt thrill those who missed out on tickets last year.
The trio have this time programmed three pieces: Arensky's Piano Trio No.1 in D minor, Beethoven's Trio in E flat and Schubert's Nocturne.
Arensky's trio is lyrical and fiery, widely considered his great masterpiece. Beethoven's Trio in E flat is hearty, good-natured and tuneful while Schubert's Nocturne, with its melodic flow coupled with rare harmonic imagination, is one of the most sublime works in the genre.
The concert is on Sunday, June 9 at 2.30pm. Book at trybooking.com/BCORQ or streetontrio.com.
