1 Introduction

This report relates to the Richard Maltese Proposed Scheme for the development of Bute

Mews, Barnet insofar as it affects the daylight and sunlight amenity to the surrounding

residential properties.

2 Planning Overview

Through the planning process the local authority will wish to be reassured that the construction

of the new scheme will not materially harm the neighbours’ daylight and sunlight beyond BRE

and British Standard Guidance.

The Local Authority will be informed in this by the BRE document entitled Site Layout Planning

for Daylight and Sunlight – A Guide to Good Practice 2011 (the BRE guidelines). This document

is the principal guidance in this area and sets out the methodology for measuring light and

recommends what it considers to be permitted or unobtrusive levels of change.

The BRE guidelines are not mandatory, though local planning authorities and planning

inspectors will consider the suitability of a proposed scheme for a site within the context of BRE

guidance. Consideration will be given to the urban context within which a scheme is located

and the daylight and sunlight will be one of a number of planning considerations which the local

authority will weigh.

3 Methodology

To quantify the effects of the Proposed Scheme we have constructed a three dimensional

computer model of the site and relevant neighbouring properties. We have then undertaken

technical analysis to measure the light received by neighbouring properties both before and

after the Proposed Scheme is constructed.

Daylight

In accordance with the BRE Guidelines, only residential properties are considered for daylight

levels. Living rooms, kitchens and bedrooms are the primary focus of the guideline

recommendations.

The initial test proposed by the BRE Guidelines is to establish if the proposed massing subtends

above a 25° section line drawn from the centre of the window/room in question. If the angle is

breached, it is necessary to undertake more detailed technical calculations such as Vertical Sky

Component (VSC) and No Sky Line (NSL).

The Vertical Sky Component (VSC) analysis assesses the amount of sky visibility at the centre of

the outside of a window face. The No Sky Line (NSL) analysis assesses the extent of the area of

a room which can benefit from sky visibility at working plane height (850mm). These

measurements are taken both before and after the construction of the proposed development.

The BRE Guidelines permit a reduction of up to 20% of the existing VSC values in situations

where the retained VSC value falls below 27%, which is the BRE recommended VSC level for

adequate daylight amenity in a suburban environment. The 20% maximum recommended

reduction is based upon the BRE stating that a change up to this extent would remain

unnoticeable. The 20% reduction recommendation is also applicable to the NSL values.

Sunlight

Sunlight is measured using a sun indicator which contains 100 spots, each representing 1% of

Annual Probable Sunlight Hours (APSH). Where no obstruction exists the total Annual Probable

Sunlight Hours would amount to 1486 hours and therefore each spot equates to 14.86 hours

of the total annual sunlight hours.

British Standard 8206 part 2 (section 5.3) states that:

“Interiors in which the occupants have a reasonable expectation of direct sunlight should receive

at least 25% of probable sunlight hours. At least 5% of probable sunlight hours should be

received during the winter months, between 21 September and 21 March. Sunlight is taken to

enter an interior when it reaches one or more window reference points.”

When a room has multiple windows, not all may be located southwards and, therefore, they

may not meet the target criteria. However, these windows may contribute to the levels of

sunlight within the room even if by 1-2% APSH. On this basis the analysis results within this

report are presented on a room basis. This is calculated by giving a unique reference to each of

the sun spots and totalling the number of unique spots the windows within a room receive for

the year and during the winter period. If two windows can see the same sun spot, then this will

be counted as one to avoid double counting.

Only residential properties that face within 90º of due south are taken into account for sunlight

analysis, the BRE Guidelines considers that sunlight to main living room windows as the most

important.

For existing residential properties, the BRE Guidelines state in Section 3.2.3 that:

“all main living rooms of dwellings…should be checked if they have a window facing within 90°

of due south, kitchens and bedrooms are less important, although care should be taken not to

block too much sun.”

5 Standard Survey Limitations

Although we have undertaken as detailed an inspection as possible, we are required by our

professional indemnity insurers to notify you that our report is based upon the Standard Terms

and Conditions provided along with our fee proposal. Our understanding of the existing

massing, including the surrounding context was established from a site visit and aerial

photography.

In addition to our standard limitations the following limitations and assumptions also apply.

Best estimates were made in establishing building use (residential or commercial) and room uses; generally, these were made from external observations and recourse to planning records where available.

When floor plans of surrounding properties were not available, room depths have been assumed from external observations. Where no indicators of room depth were available a standard of 4m, 6m or 8m depths have been used.

In accordance with BRE Guidelines1 balconies, where present have been removed from calculations.

6 The Site

The site is located in the London Borough of Barnet.

Drawing Number P1191/02 Existing Buildings

Our understanding of the site location and existing building that occupies the site can be seen

within drawings P1191/01-02 and can be found within Appendix A.

Drawing Number P1191/04 Proposed Scheme

Our understanding of the proposed scheme is illustrated in drawings P1191/03-04 located

within Appendix A.

8 The Surrounding Properties

The following surrounding properties contain residential accommodation and, due to their

proximity to the development site, have been assessed in terms of the effects of the proposed

development upon their daylight and sunlight amenity:

- 14 Falloden Way

- 16-20 Falloden Way

- 22 Falloden Way

- 24 Falloden Way

- 26 Falloden Way

- 28 Falloden Way

- 30 Falloden Way

- 32 Falloden Way

- 34 Falloden Way

- 36 Falloden Way

- 38 Falloden Way

The location of these properties can be seen in the drawings within Appendix A.

Detailed results for each window/room assessed can be found in Appendix B and are

summarised below.

14, 16-20, 22, 24, 26, 28, 30, 32, 34, 36 and 38 Falloden Way

Located to the north of the development site this property appears, from external observation

and review of the local council tax registry, to contain residential accommodation. We have

only assessed windows/rooms up to first floor. The windows/rooms on the upper floors being

higher up and naturally receiving better levels of daylight and sunlight.

Daylight

There are 74 windows serving 39 site facing rooms. All windows and associated rooms

experience fully BRE compliant alterations in both VSC and NSL; the greatest alteration in VSC

being 1.97%.

BRE guidance provides that reductions up to 20% will be unnoticeable.

Sunlight

All rooms with site facing windows orientated within 90 degrees due south are fully BRE

compliant in terms of any alteration in Annual and Winter Probable Sunlight Hours.

In accordance with BRE guidance, the occupants will not notice a change in sunlight amenity.

9 Conclusion

Daylight to Surrounding Residential Properties

Full technical analysis indicates that all habitable rooms within residential properties

experience alterations in VSC and NSL well-within keeping of the BRE recommendations.,

meaning the occupants will not notice a change in their existing levels of daylight.

The proposed scheme demonstrates full compliance with BRE guidance in terms of daylight

amenity.

Sunlight to Surrounding Residential Properties

Full technical analysis indicates that all residential properties experience alterations in APSH

well-within keeping of the BRE recommendations, meaning the occupants will not notice a

change in their existing levels of sunlight.

The proposed scheme demonstrates full compliance with BRE guidance in terms of sunlight

amenity.
