Requirements for converting a traditional layout to open-plan vary greatly from project to project. Rather than breaking down the cost of each element, it’s more useful if we explore what can be achieved within different budgets by showing you some of our actual open-plan renovations.

Adopting an open-plan layout has become hugely popular in the past few decades. As a modern take on interior design, it also encourages socialising and is great for families with young children to keep a watchful eye on.
Since open-plan is a general design concept, it’s difficult to pinpoint exactly how much creating such a layout might cost, given all the variables. However, there are a few aspects that most open-plan conversions have in common: the size/scope of your renovation, structural considerations, products used, and joinery.
To help you get a better idea of what it costs to create an open-plan layout, we’ll outline how these main budget drivers affect the bottom line. With this information, you’ll be able to consider your priorities, compare similar projects on our website, and assess what you may spend.
Some budget drivers may have more impact than others, depending on your desired result, but there is usually room for compromises and splurges. Working with a Refresh Renovation Consultant is the best way to reach an accurate budget for your open-plan renovation but we’ll provide actual renovation costs and project details to help you get a better understanding of what can be accomplished within different budgets.

## Products used
Two main motivations behind a renovation are budget and design. During a budget-led renovation, homeowners have a strict figure in mind and want to accomplish as much as possible within that budget, whereas in a design-led project, homeowners have a specific design in mind and are willing to spend whatever it takes to achieve it.
Product choice can make or break a budget, but it doesn’t have to. Nowadays, there are plenty of cost-effective fixtures and finishings that give you a high-end look without compromising value.

## Joinery
Joinery isn’t always at the forefront of your mind when considering an open-plan layout, yet it can play a crucial but costly role. Adjusting the interior layout may require removing or adding windows and doors to keep the flow of your home optimal.
This renovation included the creative use of joinery for a curated layout that was perfectly suited to the homeowners’ lifestyle. The design utilises a glass-panelled cavity door to offer the option of separation for a semi-open layout. The 90m2 renovation was completed for $156,000*. (APR 2022)
