The Hampshire and Isle of Wight Air Ambulance has been given a £1,500 boost.
Barratt David Wilson Homes' Southampton division has donated the sum to aid the charity's Operation Airbase appeal.
This appeal is the charity's largest fundraising effort to date, with the aim of relocating its airbase to a more central location in the region.
The move would allow the team to reach nearly every patient in Hampshire and the Isle of Wight within 10 minutes of take-off, cutting the current response time of 20 minutes or more in half.
The Hampshire and Isle of Wight Air Ambulance are called out to an average of five incidents every day, including cardiac arrests, road traffic collisions, falls, and assaults.
The service provides crucial care to the most seriously ill and injured patients in the region.
Keith Wilson, director of income and engagement at the Hampshire and Isle of Wight Air Ambulance, said: "Operation Airbase will be the single biggest leap forward in our 17-year history.
"Getting to our patients even faster will give our crew every opportunity to get that patient to hospital alive and for that patient to return home to their family and friends.
"We are incredibly grateful to the people and businesses like Barratt in our local community who support our vision to save time and save lives."
The service operates 24/7, 365 days a year, bringing the emergency department to patients wherever they may be, whether that be beachside, roadside, countryside, or bedside.
The donation from Barratt David Wilson Homes will contribute towards the advanced critical care the charity provides.
Tamsin Nichols, marketing co-ordinator at Barratt David Wilson Homes’ Southampton Division, said: "We are committed to supporting organisations in the communities in which we are building.
"Hampshire and Isle of Wight Air Ambulance provides a vital service that’s available free-of-charge to everyone in the county and we are delighted to be able to support the amazing work they do."
Barratt and David Wilson Homes’ Community Fund is a dedicated financial resource that helps to support local causes which improve the quality of life for those living in the region.
