Transforming local homes

MYD Studio London's focus lies in working with local homeowners to build, expand and improve their homes. We're also happy to work with property developers too. We can design new builds, loft conversions, outbuildings and create plans for a change of use within a building (such as converting a property into flats).

Our architects will work with you every step of the way and offer advice regarding party wall matters and building regulations.


Our development and delivery strategy

MYD Studio London bases our design and project delivery methodology on the RIBA Plan of Work 2020 which is the accepted standard building design and construction process in the UK. We have a flexible approach to the scope of our services based on the scope of work in the project.


Stage 0 - Strategic definition

We’ll give a free consultation at the project's site to establish your requirements and budget and to study site conditions and to determine the best approach for the project.

Stage 1 - Preparation and briefing

We’ll prepare an initial report with your finalised requirements, possible design strategy and site study.

Stage 2 - Concept design

We’ll create some initial concept sketches and your preferred idea will be developed into a complete concept design presentation.

Stage 3 - Spatial coordination  

This is where we develop your approved concept further into schematic level drawings. This stage includes any planning submission that may be required. By the end of this stage we are in a position to understand the final outcome of the project and how it will look.

Stage 4 - Technical design

Building Regulations submission is the main task at this stage. The local authority will assess the compliance of the scheme with the regulations, including information prepared separately by the structural engineer. If necessary, we can help you find appropriate contractors to carry out the building work.

Stage 5 - Construction

Although we don’t offer project management services, we can offer support during the construction process.

Stage 6 - Handover

This happens after conducting testing and commissioning.


Permitted Development Rights

Homeowners in London have a variety of development rights for their properties. We can help you to transform your home.


Rear Extensions

Two Possibilities: 
6 meter large Rear Extension:  

  • Prior Approval Application required. 

  • Neighbour may object and it can have implications on decision.

3 meter Rear Extension:  
Permitted Development rights. Planning Approval not required. Simple application.


Majority of Victorian houses are cut off from the garden due to utility rooms being at the rear of the house. Rear extensions should be used to create harmony between the house and the rear garden.

Side Return Extension

Side Extensions to the houses are an ideal strategy to increase the interior space. Internal layout remodelling should intelligently be done to enhance efficiency and cohesion. Side extension can be at the full length of the house but not exceeding one third of the total width of the existing dwelling.

Factors to consider:

  • Extensions (including previous extensions, shed and outbuildings) and other buildings must not exceed 50% of the total area of land around the original house. 

  • Extensions in front or beyond front elevations are not Permitted Development.

  • On designated land (Including Conservation Areas), extensions are not permitted development.

  • On designated land (Including Conservation Areas), double storey extensions are not Permitted Development.

  • Single storey extensions maximum allowable height is four meters.

  • If the extension is within two meters of the site boundary, eaves height should not exceed 3 meters.

  • Maximum eaves and ridge height should not be higher than the existing house.

  • Extension of more than one storey must not extend beyond the rear wall of the house by more than 3 meters or be within seven meters of opposite boundary.

  • Roof pitch of two storey extensions should match the existing house roof pitch, to be a Permitted Development.

  • Upper floor windows to be obscure-glazed and fixed glass, unless opened at 1.7 meters or above.

  • No balconies or verandas are allowed in Permitted Development.

Loft Conversions

We’ll create some initial concept sketches and your preferred idea will be developed into a complete concept design presentation.

Loft conversions are an excellent and cost effective option to maximize space at upper levels of the house.


There are four main types of Loft Conversions:

Dormer Window Extension: 
The simplest way to get more internal space at the roof level is to add a dormer window, which will add internal space and bring natural light at this level, creating a habitable space which can be used as a Bedroom, Study, Gym. Etc.

Full of Partial Loft at the Rear: 
This type of addition at roof level provides considerably more additional space within. This kind of Loft Conversion provides much more flexible options for the utility of this additional space.

Side Hip-to Gable Extension:
This type of extension is ideal for detached and semi detached houses. This option provides significant opportunities for expansion.

Mansard Roof Extension: 
This extension is ideal for houses with “V” Roofs. This type of extension is ideal for Conservation areas.


Factors to consider:

  • 40 cubic metres for terraced houses.

  • 50 cubic metres for detached and semi-detached houses.

  • An extension beyond the plane of the existing roof slope of the principal elevation that fronts a highway is NOT a Permitted Development.

  • Materials are to be similar in appearance to the existing house.

  • No part of the extension is to be higher than the highest part of the existing roof.

  • Verandas, balconies or raised platforms are NOT a Permitted Development.

  • Any windows must be obscure-glazed and non-opening unless the parts which can be opened are more than 1.7 metres above the floor of the room in which it is installed.

  • Roof extensions, apart from hip to gable ones are to be set back at least 20cms from the eaves. The 20cm distance is measured along the roof plane.


Outbuildings include sheds, play houses, green houses and garages and other ancillary buildings such as swimming pools, ponds, sauna cabins, etc. On designated land outbuildings to the side of the house are not a Permitted Development. Outbuildings are not permitted within the grounds of a listed building.

In national parks, the Broads, Areas of Outstanding natural Beauty and World Heritage Sites the total area to be covered by any outbuilding more than 20 meters from ANY WALL of the house must not exceed 10 square meters to be a Permitted Development.

Outbuildings are not permitted forward of the principle elevation of the original house. Outbuildings and other buildings must not exceed 50% of the total area of land around the original house. Sheds and all other outbuildings and extensions to the original house must be included when calculating this 50% limit.


The outhouse must not be used for living accommodation and must have no microwave antenna. Outbuildings must be single storey with a maximum eaves height of 2.5 meters and a maximum overall height of 4m with a dual pitched roof, or 3 meters in any other case. If the outbuilding is within 2meters of the property boundary the whole building should not exceed 2.5 meters in height. Balconies are not a Permitted Development. Raised platforms such as decking are a Permitted Development provided they are no higher than 300mm. Containers such as those used for domestic heating purposes, must not exceed 3,500 litres capacity to be a Permitted Development. The other Permitted Development conditions which apply to outbuildings listed above also apply to containers.

Flat Conversions

Flat Conversions

Important points:

  • Property should have enough interior space to be complying for conversion policy.

  • Each flat has its own entrance.

  • Comply with Housing Design Standards and required areas.

  • Should have a boiler and storage.

  • Should have bicycle storage.

  • Should have proper waste disposal arrangements.

Change of Use

To apply for a change of use of premises, one may need planning permission from your local Planning Authority.
