Home Extensions Old Guildford
Built For The Way You Live
Old Guildford features predominantly brick homes built from the 1960s through to the 1980s, sitting on generous blocks that typically range from 550 to 700 square metres. Many of these original homes were built with compact floor plans and limited living space, making them perfect candidates for extensions that can deliver the extra room growing families need. With solid foundations already in place, extending outwards or upwards is often more practical and cost effective than selling up and moving.
We’ve completed extensions throughout Old Guildford and across Guildford, Merrylands, Yennora and the wider Canterbury Bankstown region, working with families who need more space without leaving their established neighbourhood. Our team understands the typical layout of homes in this area, from the brick and tile builds on Woodville Road through to the fibro and weatherboard homes closer to the railway line. We know what works structurally and what adds real value to properties here.
Old Guildford remains affordable compared to inner Sydney, with many young families and multi generational households choosing to extend rather than upsize elsewhere. Adding a second storey or rear extension can transform a three bedroom home into a four or five bedroom layout, giving everyone their own space while staying close to Guildford Station, local schools and established community connections. A well designed extension can add significant value to your property while making it genuinely liveable for your family’s needs.

Don't Take Our Word For It
"I contacted Monstructions to get an idea of a price for doing an extension on my home. Of course I contacted many other people but they were the only ones who came back to me and assisted in giving me an idea of the price. I was so grateful. I wouldn't hesitate in recommending this company as we couldn't be more happy with the team, thank you for your help and support."

"We had a plan of what we wanted with our 2nd story + granny flat addition, but also had a budget to meet..the Monstructions team worked hard to make that happen for us. With a few little hiccups along the way from weather delays, the boys kept the job moving as smoothly as possible and the team were amazing in keeping mess to a minimum. Allowing us to stay at home during the reno. 100% highly recommended!"
