London’s best known professional kitchen extension team!

The term ‘kitchen extension’ can refer to many different types of house extension.

When a kitchen extension is built primarily to facilitate the installation of a new kitchen. These are most commonly side return extensions, side extensions or rear extensions. The most suitable extension for your home will very much depend on the type of property that you own. If there is a house on your road that already has has an extension you can get a fair idea of what you are to expect that will be your indication of what has passed building control.

Whether you can go higher, lower or further will be dependant upon planning permission.

Types of Kitchen Extension

wraparound-kitchen extensionWrap Around Kitchen Extension

A wrap-around kitchen extension is a rear extension combined with a side return extension.  The wrap around extension provides maximum space and dramatically alters the ambience and shape of your house.

If you want to achieve a bright airy open plan kitchen, a dining area & a social gathering space all in one area, then a wrap-around extension is the top option for you.

This style of open plan living has migrated over from the US and is becoming ever more popular here in the UK.

We have witnessed this type of space working well for growing families.

Rear extensions extend out from the back of the property into the garden space. Full width rear extensions are typically carried out on properties where there is no side return or the property is semi / fully detached. They most commonly extend from 4  to 10 meters in length from the rear of the house for the full width of the house. These projects often significantly increase the ‘meter sq’ area of the kitchen.

A rear extension is the ideal option to go for if you spend a lot of time in the kitchen. Most often these kind of kitchens are big enough  to accommodate island units. Large rear kitchen extensions are not only good for large families, but they are also perfect for those that love to entertain in outdoor space.

Typically, these kind of renovation styles are separated into three areas – the kitchen, the dining area and the seating area – so that when your entertaining, your guests can mingle & choose which part of the room they want to reside.

APT Renovation can take care of all aspects of your bespoke kitchen extension project. We can generate designs and measurements of your project, then subsequently keep the ball rolling whilst guiding you though the whole process. If you don’t already have an architect, we will start off by submitting your project to planning permission, passing the building regs, and navigating the highly restricted building control process.

We have a history of creating exceptional residential extension. We are highly skilled combining clients’ ideas with our expertise in the construction of bespoke ground rooms and cellars.

Why Choose us for your Kitchen Construction Work.

Our in-house team of qualified Architectural Designers and fine Builders are capable of undertaking any project, small or large.

Our first step towards building your project will be to arrange a free site visit to your home. We will discuss your ideas for a basement or cellar conversion, and create a design brief. This brief defines our objectives. Using our extensive knowledge and experience, we will advise you where the design might need to be altered, in order to maximise the proposed changes, and we will strive to exceed your expectations.

Once you have approved the initial design, APT Renovation can take care of all the necessary plans etc., submitting the basement or cellar designs as part of the planning application. We can also deal with all issues relating to party walls, when required, and to the Building Control process.

We will act as your agent, so you really only need to pay the required fees and wait for the decision. We ensure that the designs that are submitted for the planning application are sound from the construction point of view, and that they do not imply any fundamental design modifications.

We work with RIBA Chartered Architects that are specialised on residential builds who collaborate with the on site building specialists to create the space that you desire.

Health and Safety at every stage

Health & Safety is of the utmost importance on every site on which we work. This is something that concerns all of our staff members, but also everyone else in the vicinity of the works, including you, your neighbours and even passers-by. Due to the nature of our work, there is always the risk of injury, or even death, as ladders, tools and various materials can be hazardous. Basement conversions, in particular, are technically very challenging, and can pose a number of different risks, with a large proportion of such projects in London regularly failing safety checks. Unguarded excavations and unprotected floor openings can represent a serious danger to all concerned. That is why our staff are expertly trained and will always diligently adhere to all necessary Health & Safety procedures and issues.

British Standard 8102:2009 is the Code of practice for protection of below ground structures against water from the ground. In essence, it is the primary design guide for structural waterproofing and groundworks in the UK, with a recent update having been released in November 2009. This document should cover every consideration relating to waterproofing design.. If you have further questions in regard to BS 8102:2009, please feel free to contact us.

basement conversion tanking and excavation

Basement Tanking

Tanking, or ‘Type A barrier protection’ (a BS 8102 definition), is a specific form of waterproofing for underground rooms and under-structures, although it is a common term applied to all forms of waterproofing. In the true sense of the word, tanking means blocking water out of a structure by employing a barrier product which is installed internally, sandwiched within, or applied externally to, a structure. ‘Tanking’ is still widely used and applied in the building industry, but has declined in popularity in recent years, where retrofit protection is required for existing basements.

basement conversion waterproofing

Waterproofing

Waterproofing is a very important aspect of basement and cellar conversion, particularly as the UK experiences a very high level of rainfall each year. A lack of waterproofing will eventually result in damp on walls, which does not have an attractive appearance. Furthermore, the resulting odours can be detrimental to hygiene, and can cause significant damage to paintwork and plaster. Worse still, damp can lead to breathing problems and other health issues, so it is something that should be eradicated immediately.
APT Renovation Design & Build has had huge success over the years in waterproofing with Delta Membrane Systems and pumps. For basement waterproofing, the Delta sealed system ensures that all membranes are expertly sealed and secured, as well as any protrusions or crevices. Delta Systems are incredibly effective in dealing with adverse water conditions, especially in basements that have a propensity to flood. There is a 30-year guarantee on all Delta membrane systems
