Home Renovations & Alterations

Interior and exterior transformations, kitchen and living upgrades, and modern finishes, delivered by a builder who cares about the result as much as you do.

Your home, transformed, without the stress

A well-planned home renovation is one of the best investments you can make, adding real value to your property while making it work better for the way your family actually lives. Hannon Constructions is a licensed renovation builder servicing Sydney’s Hawkesbury and Hills District, specialising in residential renovations from single-room upgrades through to complete whole-home transformations.

Ryan leads every renovation and alteration personally. You won’t deal with a project manager who wasn’t at the first meeting, you deal directly with the person making the decisions, from first conversation to final handover.

Whether your home needs a new kitchen, a modernised bathroom, an open-plan living upgrade, or a full interior and exterior overhaul, we’ve delivered it all across the Hawkesbury, Hills District, and wider Sydney basin, and we’ve done it to a standard our clients are proud to show off.

How It works

Your home renovation, step by step

1 Tell us about your project

Once you get in contact with our team we will ask you to complete an online form which helps us understand your project goals, budget, timeframe, inspiration and overall vision of your project. We organise a phone call – Ryan personally calls you to discuss your project in detail, answer questions, explore ideas and determine the best next steps for your renovation or build.and ensure it aligns with our expertise, values and service area so we can deliver the best possible experience and outcome.

2 Initial Site meeting

We meet onsite to review your home, discuss ideas, explore possibilities, assess challenges and begin shaping the scope, vision and strategy for your project.

After the meeting, we provide detailed notes, recommendations and the next steps required to move your project into the planning and design phase.

We collaborate closely with you and your architect/designer to refine layouts, selections, functionality and construction details before pricing begins.

3 Approvals & planning

We handle the paperwork From council approvals to engineering sign-offs, we manage the documentation process so you don’t have to. Tara coordinates all scheduling, compliance, and pre-build administration, keeping everything on track before a single nail is driven.

4 Build & handover

Ryan is on site, every step of the way. We’re not a company that quotes and disappears. Ryan is hands-on throughout the entire build, managing trades, maintaining quality standards, and keeping you updated at every stage. You’ll always know where your project is at.

We’re not done until you’re happy Final walkthrough, defects rectified, and a thorough handover. We don’t consider a job finished until every detail is right. And we’re still contactable after handover, because the relationships we build with clients matter as much as the homes we build for them.

Professionalism and workmanship second to none

Just a small note of appreciation for the work you completed at our home. We have used a number of different tradesmen over the years and you have been by far the best tradesman we have dealt with. Your professionalism, workmanship and communication are second to none.

The project ran flawlessly, and with you being so meticulous with the quality of your work, the end results are amazing. We are extremely pleased with the results and have received numerous compliments.
We found it so much easier to work with a tradesman who kept us informed at every step along the way and completed the work upon the agreed timetable.

We would not think twice about using your services again in the future or recommending your work to our family and friends.

Stuart & Lana, Baulkham Hills

Delivered the highest possible quality, beyond our brief

We were referred to Ryan through another tradesman who we knew was a perfectionist so we had every faith that Ryan and his team would be able to deliver the high standards of building and finishes we wanted.
Every step of the way we knew Ryan had our best interests at heart and he often went beyond our brief to ensure he delivered the highest possible quality.

Ryan was able to plan ahead, stay on budget and provide excellent service and advice at all times.
We have no hesitation in recommending Hannon Constructions – in fact we have done it already and would do it again!

Nigel and Rebekah , North Rocks

So happy, we've already contracted Ryan for a second project

We decided to run with a local builder Ryan Hannon from Hannon Constructions to do some renovations to our house. After speaking with Ryan and listing to his ideas and vision my wife and I could not be happier with the end result.

From start to finish nothing was a problem for Ryan and his team, we wanted a few changes along the way, and he went beyond what was required to make sure that the job was finished and completed to a very high standard.

To anyone thinking of contracting Hannon Constructions to Build, Renovate, Fix Up, Change, Alter anything we would recommend them with the utmost confidence that you will get a fantastic job from a very hard working and most importantly honest man who knows his trade extremely well.

We were that happy with the results, we have already contracted Ryan to start a second project at home for us.

Common Questions

Home renovation FAQs

Do I need council approval for a home renovation or alteration?

It depends on the scope of the work. Minor internal renovations typically don’t require approval, but structural changes, extensions, or alterations that affect the building’s footprint often do. We’ll advise you upfront on what’s required and manage the approvals process on your behalf.

How long does a home renovation take?

Every residential renovation is different. A single-room upgrade might take a few weeks; a whole-home transformation can take several months. Ryan will give you a realistic timeline at quoting stage and keep you updated throughout the build.

Can you renovate while we're still living in the home?

In many cases, yes, and we’ll plan the build sequence to minimise disruption to your daily life. For more extensive house renovations, we’ll be upfront about whether temporary relocation makes more sense.

What areas do you service for home renovations?

We’re a Hawkesbury-based renovation builder working across the Hills District and wider Sydney basin, including Baulkham Hills, North Rocks, Windsor, South Windsor, and surrounding suburbs. Get in touch if you’re unsure whether we cover your area.
