Second Storey Addition — Canterbury
Extra bedrooms and living space added above, with the home's street character kept intact.
Building design is the planning, drafting and documentation that turns your ideas into council-ready and construction-ready drawings. With us, the team that designs your home is the team that builds it.
No costly handover gap between an architect and a builder. No design that blows the budget. No surprises when it’s time to price. We design to your budget from day one and stay accountable to completion — across modern, contemporary and period homes alike, with deep heritage expertise when your home calls for it.
No designing in the dark and discovering the cost later. We shape your extension or renovation around your budget from the very first sketch.
It means the design you fall in love with is the design you can actually build — locked in with a transparent, fixed-price contract before work begins. No blow-outs, no nasty surprises at tender.
Victorian, Edwardian, Federation and Californian Bungalow homes are our specialty — we extend and renovate them without losing what makes them special.
Our designs sit seamlessly behind original rooflines, preserve streetscape character, and open up bright, connected living inside — the kind of period expertise a generalist simply can’t match.
Planning permits, building permits, heritage-overlay approvals and council liaison — all managed by us, so you don’t have to navigate the red tape.
From your first consultation to your final inspection, one accountable team carries your project the whole way — backed by a 10-year structural guarantee.

Incredible result from Period Extensions & Design in Camberwell. Frank and the team have a real talent for making a heritage extension blend seamlessly with the original house. Superb craftsmanship and excellent service from start to finish. If you’re looking for a quality builder, I can highly recommend them!Posted on Holly HanssonTrustindex verifies that the original source of the review is Google. The extension to my house in Croydon was carried out by Period Extensions & Designs. The process from start to finish was managed well and I am very happy with the end result. Thanks to Michael and the team and would recommend them to anyone.Posted on EmTrustindex verifies that the original source of the review is Google. I had a great experience! Period Extensions were very helpful with all questions I had about the process of renovating.Posted on Hugh DavisTrustindex verifies that the original source of the review is Google. We recently completed a full renovation of our very run-down Californian Bungalow with Period Extensions, and we couldn’t be happier with the result. We began the project with little knowledge of what was involved, but we had a clear vision of what we wanted to achieve. Period Extensions guided us through the entire process from start to finish, and the team led by Michael was exceptional. They managed the project with outstanding professionalism and care, walking us through every step. Their project management took all the stress out of what was quite a complex renovation — including navigating heritage requirements — keeping everything on schedule and communicating clearly throughout. The restoration work on our aging house was remarkable. They brought back its original charm and character while seamlessly incorporating a stunning modern extension. Our once tired and deteriorating home has been completely transformed into a beautiful, functional space that we absolutely love. Their attention to detail, quality craftsmanship, and commitment to bringing our vision to life truly set them apart. We couldn’t recommend Period Extensions more highly to anyone looking to restore and update their home. Thank you for making our family home a reality!Posted on Gerald DavisTrustindex verifies that the original source of the review is Google. We gave Period Extensions and Designs an unenviable challenge to restore our somewhat decrepit 100 plus year old californian bungalow. Bricks had come loose, internal ceilings walls and floors were shabby, mouldy and collapsing and old lean to verandah was virtually unusable as a living space. As well, outside stucco and other renderings had cracked and fallen off. The good thing about PED’s set up is that they project manage expert tradesmen in every field of building requirements including bricklayers, plasterers, carpenters, electricians, plumbers snd painters. If they don’t have a trade on hand they recommend an expert. The building was expertly repaired and restored in a timely manner to a very high standard and a sunroom, new laundry and ensuite bathroom added as well. My wife and I couldn’t be happier with the result. We thoroughly recommend PED them to anyone wanting to renovate an old home. Gerald and Debbie Davis Kew East Victoria The PED teamPosted on Craig BatesTrustindex verifies that the original source of the review is Google. We recently renovated our 1927 Californian Bungalow with Period Extensions and Designs and couldn’t be happier with the result. Although our home had a previous extension, the layout and finishes—particularly in the kitchen and bathrooms—were outdated and problematic. From the start, the team was collaborative and responsive, working closely with us to create a design that met our family’s needs. They offered several thoughtful options and integrated seamlessly with our interior designer. The quality of the build was outstanding, with skilled tradespeople clearly experienced and trusted by the company. They were flexible during construction, making necessary adjustments and helping address underlying issues in the house. Communication was clear and consistent throughout, and the project was completed on time. We highly recommend Frank, Rod, Michael and the entire team at Period Extensions and Designs for any renovation work.Posted on Suzanne CooperTrustindex verifies that the original source of the review is Google. I loved working with Period Extensions! From my initial consultations with architect Natasha, building team lead by Michael and all the delightful trades I could not be more thrilled! I lived through the extension and renovation and the team were always wonderfully polite and conscientious. The office staff led by Nicola were also a dream and so very helpful! Thank you for my wonderful expanded home.
