Building Tectonics were very helpful and professional right from the onset . We had a small extension project , I was unaware of the procedures involved in obtaining a planning permission, after some consultation Tony and his team guided us through the process. I have no hesitation in recommending the Company .


We had been considering converting our loft space for some time but were concerned that the available space was too small for what we needed.
Luckily, a friend recommended us to get in contact with BTL – which we did.
When we spoke with Tony and his team at BTL, they offered us a feasibility study to see if what we wanted to do was possible.
We were amazed at the original ideas and free-thinking that made the space available not only come to life, but it soon became apparent from the plans that we could actually have more usable space than we actually thought possible.

Thank you for your help, original ideas and personal service.


My main contact at Building Tectonics (BT) was Tony Keller. We purchased the property in March 2010. We loved the area and wanting to extend the kitchen, creating a larger space with separate utility room. BT were extremely professional and supportive all the way! They provided many designs and discussed options with us. We have also asked BT to help with all there was to do with planning & building regulations and permissions, as well as structural engineering. We were very lucky also with the builders, but the project would have even started if we didn’t have the support and guidance of Tony and his team first.
We are embarking in the second phase of the extension now, this time: garden room, added dressing room and extra bedroom…
Of course Building Tectonics are helping again!


Thank you for the initial drawing, they are excellent food for thought and the mood board of materials also helps.


The project was delivered on time to a high spec, Building tectonics engaged with us throughout the process ensuring that changes were managed. I would recommend Building Tectonics”.


Thanks Tony for recommending I use prefab roof trusses on my loft conversion and extension.  Not only did it give me the ability to have a much wider open plan kitchen family room but it was significantly cheaper.  My builder quoted me 12k but I ended up paying just under 7k.  Thanks again, Terry’


Working with Building-tectonics was a very useful step for us.  We wanted to make our house work for our family but didn’t quite know the direction to take.  Building-tectonics gave us a selection of different possible routes that made us look at our home in a completely different way.  Nothing was too much trouble.

Building-tectonics gave us a list of builders that they felt would be appropriate, we chose one company and they proved to be superb in every way.

We now have a very different and a very special home.


Given the choice of projects within a limited budget our members chose to have a toilet installed on our Eaton Avenue allotment site.

Following a generous financial grant from the Big Lottery Fund towards the provision of an environmentally friendly composting toilet, we were grateful for the help from Tony of Building Tectonics in obtaining the necessary planning permission.  This was done without fuss and quickly, enabling us to have a grand opening of the toilet by Iain Stewart MP, within a few weeks at an open day for the public.

My brief to Tony was slightly different to the norm.  I needed planning permission on my property to add value to the sales price, as I am relocating to France. 

Tony finally did about 5 schemes / drawings for us, tweaking them along the way until we arrived at the final set that I was happy with.

Even after he did the final set, and our business was concluded, I have found Tony and his company really helpful.  I have gone back to them and have asked for artist impressions as to what the final development will look like, so that I may use these to aid the marketing of my property on the sales market.  These were done by Tony and his team without question.


Having previously worked with Tony and Building Tectonics on a social housing development, and knowing Tony from the networking scene in Milton Keynes, Building Tectonics were the first point of reference when trying to articulate our ideas.  At the time, I was working for a home improvements company, and we had decided that we wanted to be able to open the back of the house, incorporating a large bifold door.

Tony took time to understand what we trying to achieve. We wanted the kitchen to feel more open, getting the family involved rather than just a room with an oven. We wanted the dining area to feel more inviting. Encourage us to make better use of the space and enjoy the room. But most importantly we wanted a large space for the boys to play, to be able to get light in, and be able to open up the back and make the house and the garden work together when the weather allowed.

Tony helped us achieve this without a doubt. We also managed to avoid any unsightly columns and make the room flow, as if it was always there.

The room now gets more use than any other, and for that we are extremely grateful for Building Tectonics efforts, and those of our builder.
