Cavendish Nearing Completion

We have been working hard on a new large and unusually shaped loft conversion with home extension over on Cavendish for the past few months and we thought we would show you how the project is unfolding. The home is a large semi detached home and we are opening up space in the with two dormers across the loft to create a huge space.

We are really looking forward to seeing the finished project here, the design and planning right up to starting building has been flawless throughout and we think we’ll easily add value to the property in terms of space and money.

If you are thinking of opening up space in your home, Foster & Co are Barnet’s favourite builders and construction company, we provide payment plans to suit your needs and have a close knit reliable team of builders that are all fully qualified and vetted working across many high end build projects in the Barnet area.

What’s Trending For London Homes in 2018

2017 was a great year for homeowners in London and Hertfordshire and we have seen a upsurge in new and innovative ways to open up your space in your home. More and more homeowners looked for loft conversions and kitchen extensions in 2017 and this trend doesn’t look like it is going to falter going in to 2018.

So we thought we would check out what is going to be hot in 2018 and what homeowners may want to look out for that will help increase the value of properties and ensure that your home is still desirable should you ever want to sell in the future.

So, in 2018 what should you be looking at in terms of house building trends?

The Hygge Trend

Hygge is the Danish word for well being and over the last 12 months we have seen this trend become more and more popular. London homes are adopting this well being feeling into the build of the homes and this achieved by using simple and more neutral materials to create the contemporary feel with the use of time defying features such as bare brick walls with the log burning stoves and creating the warm features such as exposed RSJ’s when appropriate with contemporary furniture.

Scandinavian techniques are always popular, but we are not talking IKEA, we are looking in to more artisan designs such as stripped parquet flooring and more clean plastering.

London homes have been adopting this method now for a year and we feel that in 2018 our customers are going to be looking more into this as well being and build work closer together to help define modern day building techniques in North London and Herts.

Open Plan Living – But A Splash of Privacy

We all know that North London homes can be on the small side if budget doesn’t allow for the bigger houses in the area, but we know that opening up your space in the build is always a build factor and open plan living gives you the space to entertain and dine and bring the wow factor to any home. However, you may want open plan living but you will also want a room in the home that has privacy which could be a reception room at the front or even a snug area in your home where you can truly get away and relax. This is perfect if you have kids too, as the oldies always need a space to unwind and relax. Snugs can be built in with partition walls off the main area and are pretty cost effective.

Crittall Doors

Are you looking for timeless elegance? Then look no further than crittall doors, this is the creme de la creme of aluminium windows and doors and those in the know, know that nothing is better than Crittall. The designs are stunning and with the new and improved advances in glazing we are seeing more and more and people choose them for kitchen extensions and home extensions rather than choosing bifolding doors. You have the cross over of contemporary with the feel of traditional which is a winning formula going in to 2018.

If you are thinking of extending your property in 2018 then crittall windows and doors should be on your list.


When you think of Barnet, Herts and London there are certain types of property that come to mind. For places like Muswell Hill you can find lovely Edwardian Terraces with stunning sash sliding windows that are architecturally different to the homes say of the Victorian era. Victorian homes are more common in the North London areas and harp back to the gothic times. So, preserving the feel of your home period property is important so you need to keep working on small cosmetic changes such as maybe aluminium windows to the rear but keep the front face of the building true to the street.

Also, it is about using materials from the local area too, this is also important in keeping the aesthetics of the home to the London area and also help the local economy which is always nice to buy local.

Where Home Office Meets Home

With the rise of technology we are seeing more and more homeowners working from home and there needs to be a balance in the home where you can separate the work environment from the main part of the house. When some homes lack space, new and innovative ways of creating space where you can concentrate away from the kids and distractions that home offices can bring. You’ll need to be creative, but this is where a good home builder comes in to play.

  • You will need to be in a great wifi area or close to ethernet points or the router in the home.
  • You want as much light as possible as this is where you will spend most of your waking day.
  • Try to sound proof the partition walls around the room.

Exciting New Home Extension on Hadley Road New Barnet

This is an exciting project we are chomping at the bit to get moving on. Our partners MSK Designs have once again come up trumps with this stunning home extension design that will provide a single storey extension to a stunning period home in New Barnet. The extension will have a flat roof and the design will be keeping in with the existing period charm of the property, something we at Foster & Co are very strict on when building onto period properties in North London and Hertfordshire.

We will be opening up the rear of the extensions with bi folding doors that will open up onto the garden space to the rear, this way they can open up the space in the home, add value and save the time and stress on moving house.

home extension build in New Barnet


Some serious machinery on Park Road in New Barnet last week! Our Development of a basement extension and refurbishment to create a brand new living space required a large crane in order to pour the concrete for the base slab of the extension. We have been putting in some serious labour to get the ground work ready and it’s great to see the build coming up out the ground now!

We love working on new projects and if you are a homeowner in Hertfordshire or North London area, we would love to hear any ideas you have to convert your space. We work with award winning architects and everything is kept local, we are a perfectly formed friendly team of people that can help realise your building needs whether that be interior work such as loft conversions, extensions, conversions, refurbishments and exteriors such as landscaping and artificial grass. Here at Foster & Co, we are your one stop builders for anything you need.






In 2015 The Foster and Co Group raised the standards of our Construction projects. The Extensions that were produced were not just an addition of space, they were feats of design that accentuated the original building whilst creating an entirely new living space. We found that our clients were looking to move in to modern living which not only included open plan spaces but also clever storage and smart technology. People are really thinking about how to use their homes and how they will grow in to them over the years. It seems to be a common consensus that whilst in previous years, families would move on to bigger properties to sustain their ever expanding families, home owners now realise that with the housing market still barely grasping at its prior success, Renovation is the better and sometimes, the only option.

That being said, it seems that when faced with limited options, rather than make do, Property owners are using the opportunity to explore what is really possible in designing their new home. Why build just an extra room when you could create something amazing with imaginative glazing, inventive use of levels and space and stunning features like contemporary staircase, slick kitchens and impressive angels.

An article that shows the true modern age of design and construction was featured in the Daily Mail on 10th December and discusses the awards for you the 2015 Don’t Move, Improve! Awards. The projects featured are similar to our own gallery and show how to really utilize your property and in particular the constrictive space that many London home owners have to work with.

See The WOW Factor With Our Extension And Loft Converison Make Overs!



The Foster and Co Group know that when you see your finished extension or loft conversion, it’s hard to remember how far that you have come!

The Foster and Co Group have found some old images of two of our properties before we completed the extension and loft conversion. Sometimes the difference at the front of the house is subtle and may not showcase how much work has gone in to the interior and the rear of the house. In others, as you can see with Friern Watch, the House had a substantial build and the change in the property is quite dramatic.

The Foster and Co Group are thrilled when we see such a great property transformed in to an incredible home. We feel that it is a credit to the entire team from our office staff who keep the company running to the trade team who are able to create such stunning builds!

Great Design Can Make A House A Home – Your Build in North London and Hertfordshire

Why Your Build In North London And Hertfordshire Needs A Great Design!

The Foster and Co Group are avid followers of great design. Your Build in North London or Hertfordshire should not only comply with planning regulations but also be designed in a beautiful and functional way. A great design for domestic development can turn your existing property in to something incredible, either using intelligent use of space to provide storage or brilliant features which can boost the financial value of your home. Whatever your reason is for taking on a Build in North London or Hertfordshire, good design should be a high priority.

An Article published in Luxury Homes and Property on 23rd September 2015 discusses a Notting Hill typical terraced property which has now doubled in value due to a brilliant Extension. This is mainly due to a great design which has accentuated every crevice and corner of the existing building and extended cleverly in the unused space. The extension uses double height where it can which give the illusion it is much bigger than it is. Double height ceilings also allow for clever glazing ideas to let in as much light as possible.

The Foster and Co Group are Construction Company that are able to work with our client in order to achieve the absolute most out of their build. Not only do we offer a budget matching service where we can submit design ideas which incorporate all your key features but within your budget but also we can assist on recommendations as the project evolves.

It is common knowledge in the building Industry that projects are subject to change whilst the building progresses. This is because drawings do not give the three dimension building full credit and often when a build begins to take shape, certain areas may need to be changed due to client preference or simple design aesthetics.

The Foster and Co Team are extremely experienced in completing a high quality Build in North London and Hertfordshire. We have perfected our talent at producing beautiful structures that have truly changed the home owner’s lives and we hope you too are inspired by our Projects.

The Foster and Co Group Triumph with a Timber Frame


At the Foster and Co Group it is important to support new innovations in design and construction. The Timber Frame method is growing in popularity and in particular across the pond in the US, it is becoming the must have methods for home builders and extenders.

An Article in the Construction Index in 2012 predicted a fast and successful rise for the Timber Frame industry in the UK and although hit by the recession slightly in 2013, good growth in 2014 means that the Luxury Lumber home industry is back on the rise and still on track to hit high targets for 2015!

An Architect with whom Foster and Co do much work with is also an advocate support of this method of building and has therefore worked with the Foster and Co Construction team to bring a design to life for current clients living in Barnet, Hertfordshire.

A Double storey extension which was only stated at the beginning of September, is in full swing with the main structure already up and looking fantastic! The momentum on the project is fantastic and the foster and Co Group are proud to see both happy tradesmen working with happy clients!

Timber Frame Buildings are have a various pros when compared with normal masonry buildings.

Below we have featured some of the most important advantages for clients who choose to build in this way.


It is the most obvious advantage of Timber Frames and one of the most attractive to Clients considering this type of construction. Not only is the actual construction more efficient and much quicker, but the Timber Frame allows all other trades such as Electrician and Plumbers to begin their works at a much earlier stage.

The weather in the UK is a sure fire way to postpone your build with many trades and bricklayers especially not being able to work in damp cold conditions. With a Timber Frame, this issue is solved due to the fact that the Timber Frame itself needs to be made water tight much earlier in the build therefor the rainy, grey days will not hinder progress the way it would with a masonry construction.

The Quality

Due to strict guidelines that apply to Timber Frames, which are in fact much sterner that that of a masonry build due to the sometime complex design, you can almost guarantee that provided the construction is properly supervised and managed, as Foster and Co always do, the Timber construction will be accurately assembled and be of the highest quality.

Energy Efficiency

The modern world offers a very different specification for home building and renovation than it did even just ten years ago. Government guidelines and a general increase in concern for energy efficiency with home owners has meant that the majority of new buildings and extensions will not just be effective in conservation of energy due to preference, but also because of meeting the conditions set out by the Government. A major advantage of a Timber Frame is that the insulation is within the depth of the structure, so a typical timber wall can be thinner than its masonry equivalent, for example, by 50mm. Timber frame structures are said to perform much higher when tested for escaped air and heat compared to conventional masonry buildings and therefore can offer brilliant energy efficiency.
