Extensions and renovations in Lake Macquarie and Sydney

Improve the home you already own with a clearer layout, additional rooms or a better connection to outdoor living. We review the existing building, the proposed junction between old and new work, and your priorities before developing the scope.

Plan around the existing home

Identify the areas to retain, structural changes, service alterations and finishes that need to connect. If you intend to live in the house during works, discuss access, separation and temporary arrangements early.

Scope, budget and construction stages

We discuss the brief and site information, develop the design and agreed works, coordinate documentation and approvals, then confirm a programme for the construction stages. The estimate needs to reflect the existing building condition and any investigation still required.

Considering a separate living space instead? Compare our granny flat supply and installation service.

Questions about extensions and renovations

Can an extension improve indoor and outdoor living?

An extension can create space for a larger living area, additional bedrooms or a better connection to the garden. The design needs to consider the existing structure, changes in levels, daylight, privacy and how people move between old and new rooms.

Can we remain at home during renovations?

This depends on the work and the ability to separate occupied areas from construction. Discuss access, dust, noise, utility interruptions and temporary kitchen or bathroom arrangements before agreeing the programme. Some stages may require alternative accommodation.

What affects the cost of a home extension?

The existing building condition, structural changes, foundations, access, service alterations and finishes all influence the scope. Investigations may be needed before concealed conditions can be assessed. Request clear allowances, exclusions and a process for unexpected work.
