Restaurants and coffee shops, as well as estate agents, could be the first to reopen, according to a report seen by ministers.
The businesses are deemed to offer the greatest boost to the economy, but the smallest risk of transmitting the disease.
To ensure they are safe, all premises would have to undergo revamps to ensure social distancing, by installing screens or distances between tables.
The new thinking is laid out in a report authored by Tory peer Lord Gadhia and GlaxoSmithKline chairman Sir Jonathan Symonds, The Sun reports.
Calling for a limited reopening of high streets, the reports says Britain must “learn to live with Covid” as it cannot be fully defeated until a vaccine is mass produced in 12 to 18 months time.
The news comes as Dominic Raab is set to announce the lockdown will be extended by at least another three weeks.
In the report, Lord Gadhia and Sir Jonathan argue: “The initial focus for reopening the economy should be on sectors that have the greatest multiplier effects with minimum risks - such as coffee shops and restaurants which support agriculture.
“The property market is another that has wide multiplier effects.
“We need to avoid a stop-start economy which would sap public morale and damage business confidence yet further.”
