On the Northern Beaches, going up usually beats moving out: a second storey captures the views your single-level home is sitting under, doubles your floor space and keeps the backyard. We design second storey additions across the peninsula, including our recent alterations and additions project in Seaforth.
Why it works
A successful second storey starts with two questions: can the existing structure carry it, and what does the height envelope allow? We assess both before design begins, working with structural engineers where needed. Then the design work starts earning its fee: stairs placed so they don't consume the ground floor, new bedrooms positioned for views and privacy, and a facade that reads as one coherent home rather than a box on a box. Council pays close attention to streetscape and overshadowing with additions; our drawings answer those questions before they're asked.
How it works
Step 1
Structure, height controls and overshadowing checked up front, so the design we draw is one that can be approved and built.
Step 2
Layout, stair position, facade and view capture developed with 3D visuals at each stage.
Step 3
DA or CDC drawing set prepared and lodged, then construction-ready documentation for your builder.
FAQs
Design work typically runs $4,000 to $15,000 depending on complexity, with DA drawings $2,500 to $5,000 and construction documentation $1,500 to $3,000 on top. Build costs vary widely; the design stage is where we keep them honest.
Many post-war brick and timber homes on the Beaches can take a second storey with sensible engineering. We assess the structure during feasibility, before you spend on design.
Often, because height, overshadowing and streetscape involve merit assessment. Some additions qualify for CDC. We check both pathways and choose the faster compliant route.
Second storeys are the signature renovation in Narraweena, Beacon Hill, Elanora Heights and Freshwater, where elevation turns an addition into a view. Servicing all of the Northern Beaches, see every suburb we cover.
