Brendan Dowd and Stephen House are the friends and business partners behind Resin Brewing, inside the old guesthouse next to Bulli train station.

After missing a self-imposed deadline of November last year - to catch the summer rush - Resin Brewing is set to open the doors on March 11.

Part of the delay was a desire to ensure they did the right thing by the heritage building - all the wooden flooring and joists were taken out and inspected for termites.

Any that passed muster, were used in the construction. The building has also kept and reused the original bricks.

"Everything that we could reuse has gone back into the building," Mr House said.

"Where we couldn't reuse something, we went out and sourced something similar, like the same species of the floorboards."

Another reason for the delay was the state of the building; it was basically a boarded-up shell that had been used as a party house by plenty of local teens.

In fact, the day the pair were going to seriously board it up, they had to kick out a few squatters.

"I thought, 'I wonder if anyone's in there now?', Mr Dowd said.

"So I went through the front door and shouted 'if anyone's in here you'd better get the hell out because this is going to be your tomb'.

"As I said that Steve got pushed out of the way by a girl who went bolting out the back window. The two other kids said 'let us out the front door'."

But the hard work is done and on Wednesday Bulli residents will get their first look inside the Station Street brewery.

Mr Dowd and Mr House - who met in the surf at Sandon Point 20 years ago and went on to work together in the environmental science field - have been homebrewing for years before deciding to go professional.

The brewery and bar takes up the centre of the building, with an outdoor deck on the western side.

The brewery has seven fermenters and there are 10 taps at the bar - the aim is to have each of them filled with a different Resin beer.

Throughout the rooms at the front is a restaurant, with a focus on slow-cooked American smoked meats from former Sandy Goodwich chef Yon Miller.

The pair decided to add a restaurant rather than just a brewery bar to appeal to a wider clientele - and it was also what they liked as beer drinkers.

"We've gone to a lot of breweries and I've enjoyed the destination breweries where you can sit down and have food and drink as well, rather than just going in to have beers and then leave to go somewhere else to get some food," Mr Dowd said.

Resin Brewing is open Wednesdays to Sundays from March 11.
