- Full Application - Granted Conditions or Reasons: View Conditions or Reasons Informative Notes: 1 )Reasons for granting: The application site is a link-detached dwelling on Lowther Road, Dunstable. The application seeks planning permission for a part single, part two storey rear extension, first floor side extension and front porch. Alterations to windows, doors, rooflights and new roof lanterns with rear Juliet balcony and solar panels. Alteration to ground floor roof line. The proposed first floor side extension would be visible to the public realm due to its siting to the side of the existing dwellinghouse. The first floor side extension would be set down from the ridge and set back from the principal elevation of the dwelling. The first floor side extension could be considered contrary to Chapter 11 of the Central Bedfordshire Design Guide, in that it would not be less than half the width of the dwelling. However given the modest width of the extension and the existing width of the single storey element of the dwelling the extension would appear subservient to the host dwelling and would not result in any detrimental impact on the character and appearance of the area. The proposed part single and part two storey rear extension would shielded by the existing dwelling and proposed built form and would not be visible to the street scene. The proposed part single and part two storey rear extension, in its entirety, would form a deep and considerable extension to the existing dwelling. Whilst the proposed extension would be large in its footprint, it has been appropriately set down from the ridgeline of the dwelling as to where it has reduced the overall bulk and mass of the proposal. Further to this, the proposal would appear subservient when viewed in the context of the existing built form. Therefore, on balance, the proposed part single and part two storey rear extension would form an acceptable addition at the application site, which would not result in any harmful impact on the character and appearance of the area. The single storey front porch, would be prominent within the general streetscene, however due to the modest proportions and appropriate design for the original dwelling house, it is considered that it would not have a negative impact upon the character and appearance of the area. The proposed rear Juliet balcony and solar panels would not be visible within the streetscene. They are considered proportionate in scale to the dwelling, and are not considered to have a detrimental impact on the character and appearance of the area. The proposed alteration to ground floor roof line would not be considered to result in harm to the character and appearance of the area. The proposed window alterations would be considered a small scale and modest development that would be considered to form a sympathetic alteration to the existing dwellinghouse, which would have a neutral impact upon the character and appearance of the area. The proposed rooflights would be considered small and modest in scale and would not be considered to result in harm to the character and appearance of the area. Neighbouring dwelling 564 Lowther Road would be screened from the proposed first floor side extension by the built form of the existing dwelling. The proposed single-storey front extension would be modest in size and set off the boundary. The proposed part single storey rear extension would be sited close to the shared boundary line and would surpass the rear projection of this property by 3 metres. Given the single storey nature of the proposal and limited projection of the proposal on this neighbouring boundary it is not considered that the proposal would result in any loss of light, loss of privacy or overbearing impact to this neighbour. The part two-storey rear extension would be sufficiently separated from 564 Lowther Road and as such would not have a detrimental impact on residential amenity. The proposed part two-storey side extension would be set 1.36m off the boundary with 560a Lowther Road. The proposed extension would pass the 45 degree rule of light outlined in Section 11 of the Central Bedfordshire Design Guide in relation to No.560a's habitable room at the first floor. As such the proposed extension is not considered to cause an adverse loss of light to this neighbouring property. The proposed part single-storey rear extension is set close to the boundary with this property. Given the separation distance, existing boundary treatment and single storey nature of the proposal it would not result in any loss of light, loss of privacy or overbearing impact to this neighbour. All other neighbouring dwellings are sufficiently separated or screened from the rear extensions, as such they would not be detrimentally impacted. The proposed balcony and first floor rear window alterations and additions due to their positioning in relation to No.560a and No.564 Lowther Road would lead to potential oblique views over their private amenity space. However, similar views would be afforded by the existing first floor fenestration and as such is not considered so significant to warrant a reason for refusal. Furthermore, the balcony is of a small scale and therefore would not lend itself to prolonged use as a terrace area. The existing property is a three bedroom dwelling and the proposed extensions would result in an increase in the total number of bedrooms to four. The Parking Standards for New Developments SPD (2023) states that for properties with 4 bedrooms, three off site parking spaces should be provided on the application site. As shown on Plan No.25/6851/04 the proposal site benefits from ample parking on the existing driveway, in accordance with the requirements of the Council's Parking Standards for New Developments SPD. The proposal was subject to public consultation and no representations have been received, the Town Council raised no objections. The proposal is considered to be in accordance with Policies HQ1, T2 and T3 of the Central Bedfordshire Local Plan, the Central Bedfordshire Design Guide, the Parking in New Developments SPD and Chapter 14 of the NPPF.Reasons for granting: The application site is a link-detached dwelling on Lowther Road, Dunstable.

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.
