From slab to frames, cladding and roofing, this dual occupancy project in Shortland is moving along nicely and heading towards lock-up.

One of the best parts of the build process is watching a collection of frames slowly transform into a place someone will call home. Every stage brings it one step closer, and it’s always exciting to see the vision starting to come together.

We’ll be sharing more progress as this one continues to take shape

We’ve completed two projects in Weston, a granny flat and a dual occupancy, and we love how well brick builds suit the character of the area.

The granny flat features 2 bedrooms, creating a solid rental income stream right in the owners’ backyard. The dual occupancy delivered two separate 3-bedroom homes, all on one block of land.

If you’re sitting on a block in Weston (or anywhere on the Newcastle/Hunter region) and wondering what you could do with it, we’d love to chat. A granny flat or dual occ could be worth more than you think.

DM us to find out what’s possible on your block.

Before you sign anything, ask your builder these 5 questions.

We’ve seen people skip these and end up with headaches they didn’t need. Save this post before you start getting quotes.
1️⃣ Are you a licensed builder in NSW? (Check the Service NSW portal, it’s free and takes 30 seconds)
2️⃣ What’s included in your quote, and what isn’t?
3️⃣ Who will be on site managing my build day to day?
4️⃣ Do you use your own trades or subcontractors?
5️⃣ Can I speak to a past client?

A good builder will have no problem answering every single one of these.
We build granny flats, dual occupancies, and new homes across the Central Coast. DM us if you want straight answers before you commit to anything.

With all the talk around the latest Budget changes, a lot of investors are rethinking what makes sense moving forward.

But one thing that hasn’t changed? The demand for well-built granny flats across NSW.

For many homeowners, building on the land they already own still remains one of the most practical ways to create an additional income stream and add long-term value to their property.

Unlike traditional investment properties, granny flats are often designed to generate strong rental returns from the outset, making them a very different style of investment altogether.

Low vacancy rates, rising rental demand, and the flexibility of adding a second dwelling to an existing block continue to make granny flats a smart option in the current market.

If you’re considering building and want honest advice around costs, approvals, rental potential and what’s achievable for your site, get in touch with the PJ Cook team.

The entryway is one of those details that quietly changes how a home feels.

A covered verandah and well-proportioned balustrade adds practicality, creates a more welcoming entrance and gives the exterior a more finished, considered look.

Simple details, but they make a big difference to the overall feel of the space.
