New planning approval | House extensions Ealing W3

New planning approval | House extensions Ealing W3

House extensions Ealing W3 – We were appointed to design the renovations and extensions for a single family dwelling at Ealing W3. We have just obtained planning approval for a single storey rear ground floor extension to create a combined kitchen, dining and living area that opens up to the rear garden. A separate submission to the Ealing planning department was made for extending the roof fully to the side and to the rear, this approval was also successfully obtained which allowed us to maximise what we could achieve for the property and for the homeowners.

We are currently in the process of preparing the required technical and structural information we will need to obtain the next set of approvals before the contractors start with the building works later this year.

Here are extracts from the case officer’s report that explains how our proposals were assessed and approved by the Ealing planning department for the single storey rear ground floor extension:

“Planning permission is sought for a single storey side and rear wrap-around extension (following demolition of existing rear extension). The proposed wrap around extension would be 2.96m deep along the eastern side elevation, 1.93m deep along the western side elevation. 4.14m wide and 2.8m high to the eaves.

Policy D4 of the London Plan (2021) states that development should be of a high quality design which responds to the pattern and grain of existing spaces and streets in terms of orientation, scale, proportion and mass, while incorporating the highest quality material and design appropriate to its context. These are supported by policy 7.4 of the Ealing Development Management DPD (2013) which states that developments should complement their street sequence, building pattern, scale, materials and detailing.

The proposed single storey wrap around extension would have an area of 11.7sqm, occupying 21.9% of the undeveloped curtilage surrounding the original dwellinghouse. The rear element would sit largely within the footprint of the existing 1.96m deep single storey rear extension, while the infill side and rear element would be 2.96m deep. With the limited 2.8m eaves height, the proposed extension would appear appropriately subordinate to the original dwellinghouse, while being constructed with material to match the original brick and fenestration details.

Overall, the proposal is not considered to incur unacceptable impacts on neighbours in terms of loss of light or privacy, in accordance with policy 7B of the Ealing’s Development Management DPD (2013) and policy D4 of the London Plan (2021).

Conclusion
Accordingly, it is recommended that planning permission be granted subject to conditions.”

New planning approval | Double rear extension Tower Hamlets E1

New planning approval | Double rear extension Tower Hamlets E1

Double rear extension Tower Hamlets E1 – We proposed and obtained approval for the addition of a double storey rear extension to a ground floor maisonette flat; the planning approval included the creation of an external terraced area and associated internal and external alterations. 

The initial planning approval was issued in June 2019 and we have just discharged the conditions of this approval which allowed for the building works to commence earlier this summer in 2022.

Here are extracts from the case officer’s report that explains how our proposals were assessed and approved by the Tower Hamlets planning department:

“The host building is an attractive former warehouse and is well preserved. However, the building is neither statutory listed nor within conservation area and the proposal will not be visible from the street. The proposed design of the extension is considered to be a subservient addition to the host property which would not compromise architectural merits, especially considering this wholly private view. Accordingly, the principle of the infill and ground floor extension is acceptable.

The design of the proposed extension is also acceptable. At the lower ground floor the infill does not extend significantly above the existing boundary wall. At the ground floor the extension extends to one window bay so does not significantly detract from the regular pattern of large crittall windows.

The windows on the proposed rear elevation are low and would not introduce an overlooking impact.

Overall it is not considered that the proposal would present any impacts to the amenity of surrounding neighbours or occupants of the host dwelling. It is therefore considered that the proposal would be in accordance with policy DM 25 of the Managing Development Document (2013).”

New planning approval | Rear house extension Enfield EN2

New planning approval | Rear house extension Enfield EN2

Rear house extension Enfield EN2 – We proposed the addition of a 4m. deep rear extension to create an enlarged kitchen and dining area that opens up to the rear garden. We made sure that the proposal could be considered as Permitted Development and we applied to obtain a Certificate of Lawfulness to confirm the property’s Permitted Development Rights. As part of the alterations we had to remodel the existing side wall that connected to the garage at the rear / side of the property.

We are now happy to announce that Enfield planning department have reviewed our submission and they have granted the Certificate of Lawfulness we applied for this rear house extension Enfield EN.

Here are extracts from the case officer’s report:

“The site includes a detached single storey with roof accommodation property situated on the south side of Cypress Avenue and is set back from the streetscene which contains a crossover with a hardstanding area.

The surrounding area is residential in character with properties of a similar appearance. The site is not located within a conservation area nor is it a listed building and.is within a surface flooding area.

The applicant provided existing and proposed plans against which the criteria for permitted development will be considered.

Enlargement, improvement or other alteration of a dwellinghouse is considered to be permitted development, not requiring an application for planning permission, subject to the following limitations and conditions set out in The Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended).

The development constitutes permitted development under Article 3, Schedule 2, Part 1, Class A of The Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended).

The development is therefore lawful within the meaning of Section 192 of the Town and Country Planning Act 1990 as amended.”

New planning approval | Single storey front side house extension Barnet N2

New planning approval | Single storey front side house extension Barnet N2

Single storey front side house extension Barnet N2 – We proposed the addition of a single storey front / side extension that set back from the front boundary wall and in line with the front elevation to create an improved access to this single family dwelling and an additional guest bedroom as well. As part of this application we also proposed the replacement of the existing polycarbonate roof with a new flat roof of a similar height; associated works were necessary to increase the height of the shared boundary wall with the adjacent property.

We are happy to announce that we have successfully obtained planning approval to extend this single family dwelling in Barnet N2. This is what the planners said in their report on our proposals:

“The property as existing has an L-shaped footprint due to a previously built two storey side extension. The host site and adjoining neighbouring property at no. 10 Red Lion Hill benefit from single storey front extensions adjacent to along street level of Red Lion Hill. The current application seeks permission to add a front/side extension along this street level which would bring the side elevation wall in line with the previous two storey addition and infill a front courtyard area. The proposed extension would measure approximately 3.7 metres in depth and 4.7 metres in width. It is also proposed to replace the existing polycarbontate roof with a new flat roof.

The proposed extension is considered to be a subordinate addition which would sit comfortably within the streetscene. The surrounding area is of a mixed character and there is not a consistent character and as such the proposed extension is considered to have an acceptable impact. The plans indicate that the materials to be used will match the existing rendered walls of the application site.

The adjoining property at no. 10 Lion Hill also benefits from a single storey extension of similar design to that existing at the host site. The proposed extension would be site behind the existing front extension to the host site which sits adjacent to the boundary with the neighbouring property. The proposal includes the replacement of the existing roof over the existing part width front extension with a flat roof design. The plans indicate that the boundary wall between these neighbouring properties will be raised to allow for this design. The proposal is not considered to cause detrimental harm to the amenities of the neighbouring occupiers of no. 10 Red Lion Hill. The applicant is reminded that the provisions of The Party Wall etc. Act 1996 may be applicable to this scheme.

Having taken all material considerations into account, it is considered that subject to compliance with the attached conditions, the proposed development would have an acceptable impact on the character and appearance of the application site, the street scene and the locality. The development is not considered to have an adverse impact on the amenities of neighbouring occupiers. This application is therefore recommended for approval.”

We are currently at the stage of preparing technical and structural information for this single storey front side house extension Barnet N2

New planning approval | Residential development and conversion to flats Hammersmith Fulham W6

New planning approval | Residential development and conversion to flats Hammersmith Fulham W6

Planning approval for a residential development and conversion to flats Hammersmith Fulham W6 – Erection of an additional floor at roof level; erection of front extensions at ground, first, second and third floor levels, and conversion of the ground floor garage into habitable accommodation; erection of a single storey rear extension; formation of a roof terrace at third floor level to the rear elevation; replacement of existing windows with new windows at the rear elevation; conversion of the existing dwellinghouse into 3 x 1 bedroom and 1 x 2 bedroom self-contained flats.

We are happy to announce we have successfully obtained a planning approval to extend a single family dwelling and convert it to a number of flats in Hammersmith Fulham W6. After working closely with Hammersmith and Fulham planners for a period of over two years we developed a scheme that creates additional residential units as part of this small development.

The existing dwelling is part of a residential terrace along Greyhound Road; a similar planning application for the creation of 4no. Flats was approved in 2016
(2016/05403/FUL) and it has now expired. A similar approval was implemented for the property next door at No99.

In summary we propose the following:
• A full height extension at the front on 4no. levels to bring the application property in line of the terrace and No.99 next door; the depth is to match the
depth approved previously for No99 and No101.
• The addition of a single storey 3.5m. deep rear ground floor extension.
• At the front elevation the size and spacing of the windows will match the pattern along the terrace.
• At the rear elevation we propose windows of the same size but the spacing will match the new internal floor levels and without the requirement for internal steps across the floor levels. To avoid having internal steps we propose a window pattern as described in the Architect’s drawings; such alterations to windows can be considered under Permitted Development.

FLAT TYPOLOGY AND OVERALL FLOOR AREAS

Ground floor
Flat 1 (2no. bedroom; 3no. person): 67.7sqm and additional access to the rear
garden.
First floor
Flat 2 (2no. bedroom; 3no. person): 53sqm,
Second floor
Flat 3 (2no. bedroom; 3no. person): 53sqm,
Third floor
Flat 4 (1no. bedroom; 2no. person): 43.2 sqm; additional upper terrace amenity
space

ENVIRONMENTAL PRINCIPLES

We have considered the particulars of the property, its location, site restrictions and opportunities to upgrade the thermal performance of the property and to create new residential units that allow reduce energy use and carbon emissions. This is our proportionate response to the requirements of this project and we aim to
achieve the following for this residential development and conversion to flats Hammersmith Fulham W6.

• Green roof
For the ground floor rear extension roof we propose the use of Bauder Xero Flor XF301 Sedum Blanket Green roof system which is the lightest self-contained
sedum blanket system available.
Vegetation: Mixture of 11 sedum species, some mosses and grasses
Substrate: Selected porous aggregate and composted green waste
Carrier components: Polypropylene mesh bonded to a vapour permeable base carrier sheet with an integral moisture retention fleece that can absorb
and retain up to 5 Litres/m² of water.
BREEAM: Selecting native species plants within a blanket further enhances the provenance of the green roof and can secure additional credits within the
‘Land Use and Ecology’ section.

• Thermal performance and low air-permeability
We aim to use high performance insulation to the new cavity walls, roof space and ground floor areas to better the Building Regulations standards and Uvalue
requirements. During the technical / structural design stage we look to incorporate the Part L – Conservation of fuel and power – Accredited Construction Details (these details focus on the issues of insulation continuity minimising cold bridging and airtightness) and the BRE Certified Thermal Details and Products Scheme as part of this development.

• Glazing and windows
We propose new argon filled doubled glazed timber framed sash windows to replace the existing windows and to improve the thermal performance of the
fabric of the building. The new window frames will be made by FSC sourced timber sections.

There are intrinsic and undeniable environmental advantages of using timber in construction, including in the manufacturing of traditional timber sash
windows, when choosing wood from sustainably managed forests. Wood is naturally renewable, low carbon, and using wood helps take carbon from the atmosphere making it the most sustainable mainstream building
product.

• Internal finishes and fittings
During the detailed design development stage we will focus on materials, finishes, fittings and systems with low environmental impact. This will include the use of low energy light fittings, low water use sanitary ware, green products and construction techniques with reference to the Greenspec® guides and product ratings.

• SUDs system
Please see information and construction details as prepared by AC Design Solutions limited.

New planning approval | Residential development and conversion to flats Islington N7

New planning approval | Residential development and conversion to flats Islington N7

Planning approval for residential development and conversion to flats Islington N7 – Single storey half-width upper floor rear extension, a new roof terrace, a new mansard roof extension, and internal alterations to create an additional 1bed flat over the upper ground floor level (new Flat B) while retaining an 2bed flat over the lower ground floor (Flat A) and retaining a 2bed flat over the two upper floors (new Flat C); associated alterations to the steps and railings at the front of the property.

We are happy to announce we have successfully obtained a planning approval to extend a single family dwelling and convert it to a number of flats in Islington N7.

This is a project we have been working on continuously since 2020 after close consultation with the Islington planning department. After a number of revisions and through a number of planning submission we have agreed a scheme that maximizes what it could be achieved for the property within the strict planning requirements for this property; this included a new mansard roof, a rear lower ground floor extension, a rear upper ground floor extension, and various internal and external alterations.

This is what the planners said about our proposals in regards to this residential development and conversion to flats Islington N7:

Lower Ground Floor Rear Extension
16. The proposed lower ground floor extension remains predominantly as approved by P2021/0028/FUL but would project 1m greater than the approved development, approximately 4.5 metres from the rear wall of the host property in total, it would also be full width and constructed to a height of 2.7 metres. It
is considered that the lower ground floor rear extension would be appropriately sized and appear subservient to the host building. It is also noted that a similarly scaled extension exists at the adjoining property.
17. The lower ground floor extension will be constructed using London stock brick to match the existing building, which is considered appropriate.
18. Safety balustrades would be installed on the roof of the lower ground floor rear extension. These would not be visible from the public realm and of a design, materiality that is considered appropriate in design terms. No objections are therefore raised in this regard.

Upper Ground Floor Rear Extension
19. The Islington Urban Design Guide SPD states that full width rear extensions higher than one storey, or half width rear extensions higher than two storeys, will normally be resisted, unless it can be shown that no harm will be caused to the character of the building and the wider area.
20. The proposed upper ground floor rear extension would be half width, and designed in a manner that is contextual and appropriate to the host building. Although double storey half width rear extensions are not commonplace within the terrace, there are examples of such extensions to the rear of No’s. 2 and 3 Medina Road. It is considered that the proposed half width upper ground floor rear extension would not be harmful to the character of the wider area in this instance.

Mansard Roof Extension
21. The proposed drawings also show a mansard roof extension, which appears to be consistent with that allowed by the planning inspectorate at the appeal of P2019/3056/FUL and as granted by the LPA under P2021/0028/FUL. The Planning Inspectorate concluded that the mansard roof extension was acceptable on the basis that it was of a scale and design that is similar to those that exist elsewhere within the terrace, particularly at the adjoining No.16 Medina Road. The roof extensions shown on the proposed drawings is consistent with that allowed at appeal and does not fall within this current
application.
22. Overall, it is considered that the proposed extensions are acceptable in design terms and appear suitably subordinate to the host property. As such proposals are considered to adhere to with adopted policy DM2.1 of Islington Development Management Policies 2013 and advice contained within Islington’s Urban Design Guide 2017.
