Your project in Upper Mount Gravatt
Upper Mount Gravatt is organised around Logan Road and the east-west connections of Kessels Road and Mt Gravatt-Capalaba Road, with the Pacific Motorway corridor on its western side. This road framework distinguishes approaches from the Mount Gravatt side from those arriving from Wishart or the southern motorway corridor.
If a home is reached from one of the east-west roads, assess the local-street pedestrian route separately from its vehicle approach.
Review the new rooms together with existing roof junctions, outdoor circulation and the route for materials to reach the addition.
Joining new rooms to the existing home
If the extension connects to occupied rooms, agree temporary weather protection and the stages when those rooms will be unavailable. Survey levels, roof junctions and existing foundations need design coordination. Where side access is restricted, discuss how materials and equipment can reach the work area before finalising the construction approach.
Planning the work
Home extensions: the project brief
Connecting the extension to your home
Investigate floor levels, roof connections, foundations and existing services with the design team. Resolve these connection details before finalising the extension layout.
Layout and outdoor connections
Consider circulation, daylight, privacy and how retained rooms change once the extension is added. Review decks and outdoor spaces as part of the overall design.
Construction sequence
Agree access, temporary weather protection and when the retained home is affected. Document assumptions before comparing prices.
What to send with your enquiry
Existing plans, survey, extension concepts and retained-room requirements. If you do not have everything yet, tell us what is available so we can discuss your plans and what needs to happen before work starts.
Questions before you begin
What needs checking where new rooms meet the home?
Levels, foundations, roof connections and retained services need coordinated design. These connection details help define the construction scope and temporary weather protection.
Should outdoor spaces be considered with the extension?
Yes. Discuss circulation, daylight, privacy and outdoor connections with your designer so the new rooms improve how the whole home works.
