Site constraints 4
Green belt: London
Inappropriate development needs very special circumstances.
Green belt policy allows a short list of exceptions, such as limited extensions and replacement buildings. Anything else needs very special circumstances that clearly outweigh the harm. Some green belt land can count as grey belt, where it does not strongly serve the green belt's purposes. The council decides this in its green belt assessment or on each application, so we do not mark it here.
Also on the record
National infrastructure project about 979 m away: The Grand Union Canal Transfer, at pre-application; Inside the Leighton Buzzard built-up area; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 3, but it predates the buildings here and the current map does not class it as farmland.

Outside flood zones 2 and 3 · No scheduled monument at the site
Checked on 6 October 2026.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.

- Full Application - Granted Conditions or Reasons: View Conditions or Reasons Informative Notes: 1 )Reasons for granting The application site is a two-storey semi-detached dwelling on Siskin Grove in Leighton Buzzard. No .16 is constructed of brickwork with a pitched roof with an internal garage within the front elevation, No. 16 is surrounded by properties of varying design. The proposal would convert the existing garage to a living space with alterations to the door with a window. The proposal would be visible from the street scene, however, there are other properties with similar front elevations nearby to the applicant. It is therefore not considered that the proposal would have a detrimental impact on the character and appearance of the area and as such is in accordance with Policy HQ1 of the Central Bedfordshire Local Plan. In terms of neighbouring amenity, the neighbouring property to be most likely affected is No. 14 which mirrors the existing front fa�ade of No. 16, due to the siting and design, it is not considered that the proposal would have a detrimental impact on the residential amenities of this neighbour. Neighbouring property No.18, north of the applicant has a similar frontage to the proposed and is considered to be sufficiently separated from the proposal for no adverse impact on residential amenities to arise. All other neighbours are considered to be sufficiently separated from the proposal for there to be no detrimental impact on residential amenity, as such, it is considered that the proposal would be in accordance with Policy HQ1 of the Central Bedfordshire Local Plan and Section 11 of Central Bedfordshire Design Guide 2023. The proposal would lead to the loss of a single garage at the property, however, single garages do not count as a parking space as per the Parking Standards for New Developments SPD. All remaining parking would be retained on the frontage of the site. As such, the proposal would retain sufficient off-street parking and is considered to be in conformity with Policies T2 and T3 of the Central Bedfordshire Local Plan. Leighton-Linslade Town Council were consulted and raised no comments. The application was subject to public consultation, no representations were received. The proposal is therefore considered to be in accordance with Policy HQ1 of the Central Bedfordshire Local Plan and Section 11 of Central Bedfordshire Design Guide 2023.Reasons for granting The application site is a two-storey semi-detached dwelling on Siskin Grove in Leighton Buzzard.

Any other consent or approval which is necessary must be obtained from the appropriate authority. 6 )Will a new extension affect your Council Tax Charge? The rate of Council Tax you pay depends on which valuation band your home is placed in. This is determined by the market value of your home as at 1 April 1991. Your property's Council Tax band may change if the property is extended.� The Council Tax band will only change when a relevant transaction takes place. For example, if you sell your property after extending it, the new owner may have to pay a higher band of Council Tax. If however you add an annexe to your property, the Valuation Office Agency may decide that the annexe should be banded separately for Council Tax.� If this happens, you will have to start paying Council Tax for the annexe as soon as it is completed. If the annexe is occupied by a relative of the residents of the main dwelling, it may qualify for a Council Tax discount or exemption.� Contact the Council for advice on 0300 300 8306.
