Israel Weltscher

When Israel founded Carlton Park Construction in 2019, it was to fill a gap in the market.

He has extensive background in both asset and property management, since 1999. He’s seen many property investments fail because of a lack of skill in getting them off the ground.

Israel watched investors struggle with finding someone they could trust to construct and manage their property developments.

Especially skilled at figuring out the most profitable way to convert a building, he ensures that his clients continuously reap a significant return.

As busy as he is, Israel is always available to talk things through with his clients. It’s no wonder they’re so delighted to have him working on their property.

Jonathan Joseph

As an independent building contractor for close to 20 years, Jonathan teamed up with Israel in 2019 to form Carlton Park Construction.

With his hilarious sense of humour and notable loud voice, if Jonathan is on your project, you know it’ll be a solid build.

He manages the tradesmen and office staff and undertakes quality assurance. Jonathan does it all with with his motivating and empowering personality.

His intimate understanding of the building trade, along with his extensive experience working with hundreds of tradesmen gives him the guts and gumption to take on large commercial property conversions.

His clients think he’s the best thing since sliced bread. We know he is.
