Hammersmith and Fulham architects | Residential architect projects

At GOAStudio London residential architecture we have extensive experience with working with the Hammersmith and Fulham planning department and we are familiar with all the relevant planning policies that might apply for your home project.

Please see below links to some of our Hammersmith Fulham residential architect projects for ideas and inspiration.

Your brief requirements, the setting of the property, and the immediate context of the property are some of the factors that will determine what home alterations the Hammersmith Fulham planners will be prepared to allow. We will advise you about what is reasonable to expect to get approval, what might be tricky but possible, and what most likely the planners will say no to.

According to the Hammersmith & Fulham PLANNING GUIDANCE Supplementary Planning Document February 2018 these are some of the key considerations that will determine the outcome of your planning application.

Below we have copied and highlighted extracts of the most relevant current policy and advice for your home project.

Summary planning and design guide | Hammersmith Fulham residential architect advice

Key principle – HS4 Rear extensions

The council will have regard to the existing established rear building lines of adjoining properties in determining applications for rear extensions which project beyond the rear building line of the property as originally built.

However, planning permission will not normally be granted for any extension if:

• The proposed extension is more than 3.5 metres in length or, where the original property has already been extended, if the combined length of the existing and the proposed extensions would project more than 3.5 metres beyond the rear building line of the back addition as it was originally built; or
• The proposed extension would extend to within 4 metres of the rear boundary of the application property; or
• The proposed extension would cover more than 50% of the open area at the rear of the property as originally built or, where the original property has already been extended, if the cumulative area of the existing and proposed extensions would cover more than 50% of the open area at the rear of the property as originally built.

Key principle – HS6 Development, extensions and alterations – scale and massing

Any proposed new development and/or extensions to existing buildings should as a general rule, not result in an infringing angle of more than 45 degrees. Therefore, depending on the circumstances of the site the following rules will apply:

• proposals that adjoin residential properties with rear gardens less than 9 metres in length to the adjoining rear boundary, the line should be measured from a point at the rear residential boundary at ground level or,
• proposals that have rear gardens (or distance to adjoining residential properties) of more than 9 metres in length to the rear boundary, should be measured at a height of 2 metres from ground level from a point of the adjoining boundary or,
• if any part of the proposed building extends beyond these lines then on-site judgement will be a determining factor in assessing the impact the extension will have on the existing amenities of neighbouring properties.

Key principle – HS7 Residential development – windows and outlook 

• Any proposed rear extension should not worsen the outlook from any rear habitable room window located lower than the proposed extension. Depending on the circumstances of the building, either of the following will apply.
• An extension to either the roof of the back addition or to the rear of the back addition should enable an unobstructed angle of 45 degrees to be achieved to any window to a habitable room on the ground floor of the back addition if that forms the sole window to that room.
• This requirement needs to be satisfied by measuring either over or around the back addition as extended; Where there is an existing rear addition, the angle of unobstructed visibility for this purpose should not be reduced by more than 15%; Where no rear addition currently exists at the level of the extension then on-site judgement will be a determining factor in assessing the effect which the extension will have on the existing amenities of the neighbouring properties.
• Any extension at the side of the back addition (being the back addition of the property as originally built) shall not extend above a height of 2 metres on the boundary with the adjoining property as measured from the ground level of the adjoining property. The roof of the extension shall have a maximum angle of slope not exceeding 45 degrees.
• Any new windows should be positioned at least 18 metres from existing habitable room windows. This will be measured by an arc of 60 degrees taken from the centre of the proposed new window to ensure there is no loss of privacy. If this standard cannot be met then windows should be designed to ensure that no loss of privacy will occur.

Key principle – HS8 Residential development – balconies and terraces

• Planning permission will not be granted for roof terraces or balconies if the use of the terraces or balcony is likely to cause harm to the existing amenities of neighbouring occupiers by reason of noise and disturbance; or, if it would result in an additional opportunity for overlooking or result in a significantly greater degree of overlooking and consequent loss of privacy than from the access point onto the proposed roof terrace/balcony. If this standard cannot be met, sensitively designed screening may be acceptable, following an assessment of its impact upon neighbouring amenity.
• Balconies and terraces should be designed to receive reasonable levels of sunlight and daylight.
