Twerton Park has undergone several expansions throughout its history, though the decades in which it saw the most development were the 1930s, 1940s, 1960s and the 1980s - including the addition of the family stand, west of The Grandstand.

The first ever game at Twerton Park was played against Bristol Rovers Reserves in the Southern League on the 27 August 1932, in front of a crowd of 2,936, in which Bath won 2–0.

[10][11] On 25 November 1934, Bath City would play Charlton Athletic, with 600 tickets being sold in two days as work continued to bring the ground up to scratch for the game.

[12] Roofing was added to The Popular Side in 1935, with the chairman, Mortimer believing it was a necessity to provide supporters with shelter during bad weather.

Twerton was badly hit, with half The Popular Side being destroyed, and much of the congregated fence blown away, as well as structural damage to the grandstand, the season was voided, with much of the city "razed to the ground.

[18] In the summer of 1946 the stadium was in discussion to be converted to an arena for Greyhound racing, with the Bath Chronicle reporting that "they might be forced to sell unless greater support was shown."

[20][21] It was planned first to move the playing field a few yards to the west to enable a bank at the Bath End, and to extend the Popular Side, with the addition of further concrete terracing.

The chairman stated: "We feel that our geographical position alone entitles us to a higher place in the sun, with Bath and the surrounding districts, we can call upon 100,000 to support league football in the town.

[22]During the 1946–47 season, work went on to improve Twerton, and rubble from bombsites around the city was "dropped at the ground" ready as hardcore for the terraces and to build up the banking.

[26] In 1956, the supporters club began work on fencing the south and west sides of the stadium, with concrete posts holding 500 yards of chain link, and an evergreen hedge to make it unclimbable.

Work began to remove 1,500 tons of earth from the Bristol End, for the construction of a temporary stand to hold an extra 2,000 people.

It was a calculated gamble by chairman Arthur Mortimer who was aware that the cost would almost held the profit margins but he was adamant that as many Bathonian's as possible should see the game.

More of The Popular Side terracing was concreted, the press had "boosted the game to such as degree" that many predicted 15,000, in fact 18,020 roared Bath City on.

Notable large home attendances during this period included; 17,000 in 1944 vs Aston Villa[28] 14,000 vs Southend United in the 1952–53 season and 11,700 at Twerton Park against rivals Yeovil Town in 1957.

New Director, Reg Ironside, announced new significant changes would be made to the ground, with the provision of a new social club, replacing the building in the car park.

On the Popular Side, Bath City had sold some of the land for housing and the cover was taken down and moved nearer the pitch, the terracing was partly removed, dropping the stand's capacity significantly, Ironside stated the reason was that a new social club would provide a large portion of the income needed to run Bath City, as gate money and various fund raising schemes were proving inefficient.

It was expected that it would wipe a third of the debts from the book but in fact, it contributed to heavy losses as hundreds watched from Innox Park above, and more climbed over the fences, when well known band, Fleetwood Mac played.

Former Chairman; Gilbert Walshaw and Arthur Mortimer's long dream of League football appeared to have moved a step closer.

Following the resignation of Chairman Manda Rigby, she claimed that the club needed to move away from Twerton Park to "sustain their finances".

The Bath End contains no roofing, and the terracing is shallow, stretching just 4-5 rows deep, the stand gets wider as it gets closer to the Popular Side.

Located opposite the Grandstand, with a physical capacity of 3,500 the terrace runs the length of the pitch and is covered by metal roofing and is all standing.

The Popular Side is home to the club's most vocal and passionate support,[48] with flags and banners being put up at either end of which Bath City are attacking.

The barriers are more commonly used for fans to lean on during matches, but when at maximum capacity, they act as protection against a ‘human push or crush.’ Twerton Park was recently prepared for redevelopment.

[55] Initially, Bath City were in discussions with private investment company; Greenacre Capital who wished to build purpose built student accommodation on the adjoining land.

The agreement was for Bath City to give up part of their land to Greenacre, in exchange for the latter to build the club a new grandstand and facilities, which would include affordable housing, a sports bar, gym, offices and community space.

[60] On 2 March 2020, sixteen Twerton-based businesses and community organisations joined in collaboration to write an open letter to The Bath Chronicle.

[61] Although over 800 people backed the new proposals, councillors of BANES voiced concerns about living conditions - with some rooms compared to "prison cells" - and the potential negative impacts of such a high student influx in a residential area.

[62] Other council members shared concerns about the student accommodation raised by planning officers, stating the scale of the seven-storey block was “excessive, visually intrusive and over-dominant”.

Twerton councillor Sarah Moore had objected to the plans, saying she considered them to be “overdevelopment with insufficient space to provide adequate housing facilities for the numbers and types of properties proposed”.

[67] On foot, the stadium is approximately 1.9 miles (3.2 km) from Bath Spa railway station, roughly a 40 minute walk westwards.
