12. 10/0197/FUL - Two storey rear extension and alterations at THE COTTAGE, HOMEFIELD ROAD, CHORLEYWOOD, RICKMANSWORTH, HERTS, WD3 5QJ for Mr I Clapp (DCES) Parish: Chorleywood Expiry Statutory Period: 6 April 2010 Ward: Chorleywood West Officer: Claire Lewington This application has been brought to Committee as at the time of writing, it was expected that this would be called in by Chorleywood Parish Council. 1. Relevant Planning History 1.1 The Cottage, Homefield Road 03/1804/FUL - Erection of a detached dwelling – Approved. This application granted full planning permission for a four bedroom detached dwelling. The dwelling followed the linear arrangement of Homefield Road, it was offset from the shared boundary with The Firs by 4m and a minimum 2.5m from the shared boundary with Haradwaith. The detached dwelling was located to the north of the existing access track to The Cottage and in front of the existing dwelling known as The Cottage. This planning permission has been implemented but only with the commencement of foundations. 04/0590/OUT - Outline Application: Erection of detached house – Approved. This application granted outline planning permission for a detached dwelling to be sited to the north of the site. The residential site outlined in the approved plans lay to the rear of Haradwaith. The access of the proposed residential site utilised the existing access to the north of Haradwaith. An approval of details application was subsequently refused for this site in August 2007 (07/1081/AOD) with a later Approval of Details application approved for a chalet style dwelling in December 2007 (ref 07/1723/AOD). This dwelling only had conservation rooflights to the first floor front elevation. 04/1911/FUL- Erection of a rear detached pool building – Approved. This application granted full planning permission for a detached pool house in the south corner of the site. The pool house was single storey, it enclosed an existing open air swimming pool located close to the east boundary. 05/0743/FUL - Erection of detached bungalow - Refused (dismissed at appeal). This application sought full planning permission for a two bedroom bungalow in the same position and size as the previously approved pool building. This application was refused and subsequently dismissed on appeal. Applications 07/1332/FUL and 07/1333/CAC for demolition of existing dwelling and detached garage and erection of 4 detached dwellings and 2 semi-detached dwellings, garages and associated access were refused in September 2007. A subsequent appeal was dismissed. The Inspector concurred with the Council’s concerns and stated, “in essence the Council’s concerns are 3-fold; the inappropriate layout proposed, the regularity of the design and the prominence of the proposed development in the streetscene. I share these concerns, particularly in respect of the proposed layout and design details.” He further stated the appeal development would be "materially more dense" than that from d:\81894199.doc(1) the existing permissions (para24). 08/0282/FUL – Erection of two pairs of two storey semi-detached dwellings (4 houses) with detached garage and associated access, parking and landscaping was refused in June 2008. A subsequent appeal was allowed in July 2009. This consent has not been implemented. 08/1963/FUL - Erection of two detached two-storey dwellings with detached garages with associated landscaping, parking and a new vehicular access onto Orchard Drive. Approved subject to a highways contribution. Not implemented. 09/0390/FUL - Erection of 2 pairs of semi-detached dwellings (4 houses) with detached garages and associated parking and landscaping and a new vehicular access on to Orchard Drive. Refused in April 2009. 09/0508/FUL- Demolition of existing garage and erection of one pair of semidetached dwellings (2 houses) to front of site with associated landscaping, parking and access. Application withdrawn May 2009 due to inaccurate plans. 09/1021/FUL - Demolition of existing garage and erection of one pair of semidetached dwellings (2 houses) to front of site with associated landscaping, parking and access. Application approved but not implemented. 09/1614/FUL Ground and first floor rear extensions to dwelling and alterations to fenestration. Application refused for the following reason: The left hand two-storey addition by reason of the increase in bulk and massing would overwhelm the roof form and half-hipped gable end of the existing building to an unacceptable degree, adversely affecting the character and appearance of the Locally Important Building which is considered to contribute positively to the character and appearance of the Chorleywood Common Conservation Area. This would be contrary to Policies C1 and C12 of the Three Rivers Local Plan 19962011. 09/1647/FUL – Erection of 4 houses and garages together with ancillary works. Application approved, currently being implemented. 10/0068/FUL: Erection of one pair of semi-detached dwellings (2 houses) to front of site with associated landscaping, parking and access. Application withdrawn due to concern in relation to impact on neighbouring bungalow. 2. Detailed Description of Proposed Development 2.1 The application site accommodates a large two-storey detached dwelling and a detached double garage. The dwelling is on the list of Locally Important Buildings in the District. The application site lies in the Chorleywood Common Conservation Area. The dwelling is of an Arts and Craft design and is considered to make a positive contribution to the local scene and wider Conservation Area. The purpose of including the building in a list of Locally Important Buildings is to safeguard the contribution of the dwelling by encouraging its retention. There are a number of large mature trees protected by the Conservation Area on the site boundaries. 2.2 The Cottage is a Locally Important Building which is considered to contribute positively to the Conservation Area. The existing dwelling is of the Arts and Crafts Style Design and the architectural merit of the dwelling has been commented upon in recent appeals, particular reference was made to this in a dismissed appeal relating to the demolition of the existing dwelling (07/1332/FUL and 07/1333/FUL) where it was noted: d:\81894199.doc(1) ‘The Cottage makes a very positive contribution to the conservation area, notwithstanding its somewhat neglected position and the later single storey addition to the rear.’ 2.3 The contribution of The Cottage to the wider Conservation Area was also emphasised in a further appeal (subsequently allowed for 2 pairs of semi detached dwellings 08/0282/FUL) where the Inspector noted: ‘The building is locally listed and, as a building of quality from the earlier part of the 20th century, I agree that it contributes to the general character and appearance of the Conservation Area.’ 2.4 The existing two-storey house is set back from the front boundary (Homefield Road) by 48m. There is an existing double garage to the front and a driveway providing access from Homefield Road to the front of the dwelling. The property has two existing access drives from Homefield Road. A secondary access is located to the north east of Haradwaith, this driveway leads up towards The Cottage. The existing site slopes steeply upwards towards the rear of the plot so the dwelling sits approximately 6m above the highway. 2.5 The north eastern boundary is heavily vegetated including large trees. This is a shared boundary with ‘land rear of Crindau’, an overgrown vacant plot. The rear boundary backs onto properties fronting Common Road. The properties fronting Common Road are on a higher level than the application site. The secondary access road to the north east of Haradwaith aligns the side and rear boundaries of this bungalow (Haradwaith) which fronts Homefield Road. Haradwaith is raised slightly above the highway level, but at a significantly lower level than the application site. 2.6 Permission is currently being implemented for the erection of two pairs of semi detached dwellings to be built either side of the existing dwelling (reference 09/1647/FUL). 2.7 The proposal seeks to extend the existing dwelling at ground and first floor level to the right hand side of the building. The extension would have a maximum depth of 3.2m at first floor level and would have a width of 4.7m. The flank wall of the extension would be set in from the flank wall of the existing dwelling by 0.1m. The extension would have A Dutch Hipped roof form and would be set down slightly from the ridge of the main dwelling. 2.8 Alterations are also proposed including works to fenestration. Two existing doors to the rear of the proposed breakfast room which projects to the rear would be blocked up as would a small window and door in the flank elevation. A window to the front of the property has also been altered and a door has been installed to the front. This is not shown on the plans. 2.9 The proposed materials would match those of the existing dwelling. 3. Consultation 3.1 Chorleywood Parish Council: Awaiting comments. 3.1.2 Conservation Officer: The house consists of the longer ridge roofed main element with half-hip to the left end (and on the front elevation, the entrance, and three ground floor windows with dormers above) across which to the right, a wing was added (circa 1931) projecting slightly forward and backward. d:\81894199.doc(1) The right hand proposed rear addition extends the right hand wing further backwards. As this follows the existing form, and does not appear from the floor plans, to require substantial demolition - the existing rear walls to the right hand “wing” are shown retained internally. The proposed alterations to the internal, first floor layout in association with the rear extension do not significantly affect the character of the building. The drawings include a small break or return in the extended flank. This would help maintain the existing character of the building by ensuring the line of the original wing remains defined. The proposed alterations to the existing single storey rear element (that postdates the main building) have no adverse impact on the character of the building. Materials and windows proposed (ref: application form) are to match. 3.1.3 Landscape Officer: Awaiting comments 3.2 Site/Press Notice 3.2.1 Site Notice: Press Notice: 3.3 Neighbourhood 3.3.1 Number consulted: Number of responses: 4. Summary of Representations 4.1 This is a locally listed building and extensions would destroy any reasons for listing. It is an ‘Arts and Crafts’ design and should be retained as far as possible in its original form. The property has a single storey rear extension which should never have been allowed. Any further additions would compound the error. From the planning history, it can be deduced that if the application is allowed the next would be to change the internal layout and split the building into flats. Alternatively, a case will be put forward to removed the locally listed status and then demolish the building. 5. Reason for Delay 5.1 N/A. 6. Relevant District Plan Provision 6.1 Policies GEN3, C1, C12, N15, N16 and Appendices 2 and 3 are relevant to the assessment of this application. 7. Analysis 7.1 Design and Access Statement 7.2 The application site is located in a Conservation Area and therefore a Design and Access Statement has been submitted detailing the design of the proposed development and access arrangements. The scope of the statement is considered to be acceptable. d:\81894199.doc(1) Expiry 24th March 2010 Expiry 12th March 2010 72 1 7.3 Design, Streetscene and Impact on the Conservation Area 7.4 The Three Rivers Local Plan 1996-2011 advises that development should not have any significant impact on the streetscene and should not appear excessively prominent. Policy C1 refers to development in Conservation Areas and states that development should preserve or enhance the Conservation Area and in particular should be: ‘Sympathetic to the architectural features of the building, adjacent buildings and wider Conservation Area in terms of siting, proportion, bulk, scale, form, height, colour, materials, elevational design, vertical or horizontal emphasis.’ Policy C12, Locally Important Buildings emphasises the above stating that the Council will: ‘Encourage the preservation of buildings on the list of Locally Important Buildings and planning permission for development affecting Locally Important Buildings will only be granted provided that the character or appearance of the existing building is not adversely affected. 7.5 The Cottage is a Locally Important Building which is considered to contribute positively to the Conservation Area. The existing dwelling is of the Arts and Crafts Style Design and the architectural merit of the dwelling has been commented upon in recent appeals, particular reference was made to this in a dismissed appeal relating to the demolition of the existing dwelling (07/1332/FUL and O7/1333/FUL) where it was noted: ‘The Council confirmed that the original dwelling was designed in 1924 by significant architects, Imrie & Angell, thus satisfying the first of 10 questions suggested by English Heritage for assessing these matters. The building is in the Arts and Crafts movement and the large 2 storey side addition designed by London architects, approved in 1931 and subsequently constructed, follows this style. The Cottage lies centrally in the appeal site, which rises from west to east. From Homefield Road, just to the west and within the Conservation Area, the building is prominent and imposing. There are glimpses of The Cottage through vegetation, from Orchard Drive, a little further to the west and outside the Conservation area. In my judgement, The Cottage makes a very positive contribution to the conservation area, notwithstanding its somewhat neglected position and the later single storey addition to the rear’ 7.6 The contribution of The Cottage to the wider Conservation Area was also emphasised in a further appeal (subsequently allowed for 2 pairs of semi detached dwellings 08/0282/FUL) where the Inspector noted ‘The building is locally listed and, as a building of quality from the earlier part of the 20th century, I agree that it contributes to the general character and appearance of the Conservation Area. As such, given the importance of the building both individually due to its architectural merit and as part of the wider Conservation Area, there is a presumption to retain and enhance the character of the dwelling in accordance with Policies C1 and C12 of the Three Rivers Local Plan 1996-2011. 7.7 The proposed extension would be set in from the flank wall of the dwelling by approximately 0.1m. This was suggested at the time of the last application 09/1614/FUL which was refused in order to retain the existing features of the dwelling and to preserve the appearance of the Locally Important Building in d:\81894199.doc(1) accordance with Policy C12 of the Three Rivers Local Plan 1996-2011. At the time of the previous application no objection was made to this element of the proposal. The plans illustrate a small break or return in the extended flanks in order to maintain the existing roof slope and gable end profile, therefore, ensuring that the character of the Locally Important Building is retained in accordance with Policy C12 of the Three Rivers Local Plan 1996-2011. Whilst the proposal does increase the bulk of the dwelling as whole; this is not considered to result in significant harm to the appearance of the existing dwelling and as such this is considered to be acceptable. The Conservation Officer has been consulted in relation to the proposed development and has raised no objection as it is considered that the development does retain the form of the building. 7.8 The proposed extension to the left hand element of the building has been removed as part of this application as this was considered to be unacceptable for application 09/1614/FUL. It was considered that the increase in bulk and massing overwhelmed the appearance of the original building to an unacceptable degree. Given that this element has been removed, it is considered that the reason for refusal has been overcome and no objection is made. 7.9 Objections have been received stating that any change of the building will result in a case being put forward to remove the Locally Listed status of the building with the intension of demolishing. It is not considered that the development would substantially alter the appearance of the dwelling and would not result in the removal of this listing. As noted above, the contribution that this building makes to the Conservation Area has been acknowledged and for the reasons cited above, it is not considered that the proposal would result in demonstrable harm. 7.10 Alterations are also proposed to the existing fenestration, involving the closing of existing openings in the rear wall of the proposed single storey breakfast room and the flank wall of the existing dwelling. It is not considered that this would result in significant demonstrable harm, particularly as the rear elevation is not readily visible from within the Conservation Area. As such, no objection is made. 7.11 In summary, it is considered that the proposed single storey extension would retain the character of both the Locally Important Building and Conservation Area as a whole in accordance with Policies C1 and C12 of the Three Rivers Local Plan 1996-2011. 7.12 Impact on neighbouring properties 7.13 The Three Rivers Local Plan 1996-2011 advises that development should not have any significant impact on the neighbouring properties and should not result in any significant loss of light or a loss of privacy. 7.14 At present, planning permission 09/1647/FUL which was granted for a pair of semi detached dwellings to be located either side of the existing dwelling is currently being implemented. As such, the impact that the development would have on these dwellings (once completed) is a material consideration. 7.15 The dwellings on plots 3 and 4 would be the nearest residential neighbours to the site of the extension and are located to the south of the existing dwelling. It is considered that the first floor extension would not result in any significant impact to the proposed dwellings. Due to the relationship between the application dwelling and plot 3, a 45 degree line has been taken (using a previous site plan provided at the time of application 09/1647/FUL) and demonstrates that there would be no intrusion. In addition, the separation distance between plot 3 and The Cottage also further mitigates any significant impact. As such the proposal would be acceptable. d:\81894199.doc(1) 7.16 The proposed development would be located to the rear of the existing dwelling, thus ensuring no impact to the existing residential neighbours to the front of the dwelling. It is also considered that there would be no impact to those neighbours to the rear of the site on Old Common Road. The back to back distance exceeding 60m and the changes in land levels ensures that no significant impact would occur as a result of the extension and alterations. 7.17 Concern has been raised as to the potential subdivision of The Cottage into flats after the construction of the extensions. Whilst these concerns are acknowledged, the plans illustrate that The Cottage would remain to be utilised as one residential dwelling. Subdivision of the building would require a further planning application and would be assessed at the time on its own merits. 7.18 Therefore on balance, the application is considered to be acceptable. 7.19 Amenity 7.20 The application site would have ample amenity for present and future occupiers of the site after the construction of the extensions. 7.21 Traffic and Car Parking 7.22 There is ample provision to the front of the site for off street car parking. As such, no objection is made to the proposed development in this regard. 7.23 Trees and Landscaping 7.24 The Landscape Officer has been consulted and comments are awaited. However, it should be noted that no objection was raised to the previous submission 09/1614/FUL. 8.
