Our Services

 New Builds and Extensions

After initial design and planning is obtained, we go straight to work from the ground up.

Our team, are highly skilled in ground works, working closely with structural engineers and building control you can be sure your new project will be sitting on firm ground. 

Depending on your choice of timber frame or brick, we quickly erect the structure adding first fix plumbing and electrics to complete the initial stages of the construction.

Working closely with the clients needs and our design team, we are able to finish the project to the highest standards.

Refurbishments and Modernisation 

From simple remodelling bathrooms and kitchens,  re-plastering and decorating, to modern designs that will simply take your breath away. Our unique designers will work with you to help you achieve the greatest look and use of light during the daylight hours.  Using fantastic designs and crisp lines to achieve a cosy home at night time.

Interior and Exterior

From outside entertaining with pizza ovens and great kitchen ideas. Here at Hi-Spec we can achieve the look for you. Offering ideas on design to really make a wow factor inside and out. Combining your new extension or build, with great inside and outside dining for you and your family.

Garden Basements

A Garden basement can be a fantastic use of space. If it is difficult to go up or out a basement may be the answer. In most cases planning permission is relatively easier to obtain as you are not altering the outside of the property. The basement sits below the garden so there are no adverse effects on neighbouring properties. Clients have different ideas on the use of a basement, from underground Spa and relaxation, to bars, cinema rooms, extra bedrooms, granny flats, swimming pools. Finished to the highest standards and with the clever use of light wells can make an underground project achieve a return of three times the cost of building outlay in some locations.

Orangeries and Garage Conversions

An Orangery is more robust than a simple conservatory, generally with a lantern centered within the roof with the use of spotlighting. It is a simple and affordable way to extend your property. Here at Hi-spec we pride ourselves on the design and construction of our orangeries either as a garden room or a knock through to extend your kitchen or lounge.

Our unique designs will really set your property above the rest.

Rear extension 

We hired Barney from hispec probably during the worst time(coved-19), they had just started and the lock down happened, to be completely honest the company continued work and worked hard to get the job completed as quickly as they could with all the restrictions in place, the job is now finished and to a very good standard, Barney was quick to resolve any issues and answered all our questions, if your looking for a job well done, I’m more than happy to recommend this company

Clock tower front extension 

Barney and the team have been fantastic the whole way through. At the start we were a little skeptical, a great price which blew everyone else away and they could start pretty sharpish... but after reading other reviews and speaking with some of their other projects, my mind was put to rest.
Had someone on site almost every day throughout the build, no mucking around, just got the job done.
Would recommend them to anyone, quality builders and all round great guys. Bravo.

Single storey rear kitchen extension with alterations to existing property

We hired Hi-Spec team to do our single storey extension with additional internal alterations. We are extremely pleased with how this has turned out - all I can say is Barney and his team helped us convert our vision of the extension into reality. We are very happy with the final result and feel that our house has transformed into a new home. The project started in May and completed in about 14 weeks which was amazing given the Covid situation affecting building supplies. Our neighbors were surprised at the pace at which this project completed. Barney is very professional and kept us informed at each and every stage of the project. He was also able to give us several suggestions throughout the project which helped us make right choices. Barney not only stuck to the original quote but also helped us source other items at good prices using his trade contacts. All the teams who worked on our project including foundations, bricklayer, roofers, electrician, plumber, carpenters did a very good job in moving the project forward. They were all fun to have around, efficient in doing their tasks to a good standard. Couple of friends who visited our house have been very impressed by the quality of work done. We Invited an estate agent to evaluate the property after the project completion.He commented On the quality of the extension adding that it would be the selling point for this house.Overall, happy with the work done. Thanks to Mick and his team for a job done well :)

2 storey rear extension 

Barney and his team set about building a two story rear extension late last year. It started out great for them but just two days into the build we were hit with the wettest winter on record. His team pushed on through wind, rain, sleet and snow. Problems with an awkward site access were overcome. Even though they were working in some pretty bad conditions, they managed to keep the place clean and tidy. The team work quickly and to a good standard. Neighbours commented on how quick it went up. Barney wanted the place done by Christmas. The world was against him on this deadline but he pretty much nailed it! They’re a great bunch to work with and would t hesitate in recommending them.

Kitchen & Porch extension 

We employed Barney to undertake a kitchen extension, rebuild a porch, upgrade a utility room, & render the exterior of the house & garage.
From first meeting Barney he gave us confidence in him & his team. The quote arrived quickly & was very clearly broken down so you knew what you were getting. We lived at the house whilst all this work was being done and his team were very tidy, ensuring the site was tidied at the end of the day. Made sure the house was secure when exterior wall was removed. All works done to the agreed budget and high standard of finish. Highly recommend Barney & his team. In fact already having them back to do other work.

Great team, special thanks to Richard, Tim, Harry , Mitchell & Darren.

 Single storey side extension with utility and complete house refurbishment; Comberton Cambs

Barney gave me a very competitive quote about which I was sceptical initially, but he stuck to his figures. The finished work is really beyond my wildest expectations, I am really, really delighted with what has been achieved. The refurbishment was particularly difficult for him as I, along with my cat, remained living in the house, but this too has been done beautifully and to a very high standard. His guys were great, very hard-working, polite and always went an extra mile or two when asked. I have just recommended him to a colleague, and I have no doubt he will achieve the same high standard for her too. Thank you Barney and team for making a dream into reality!

 Small Garage conversion into dining room ; Duxford

Hi spec were brilliant they did everything I wanted they. I could 
Not have hoped 
For a better builder. Thank you I love my new room. Zoe

Garage conversion into kitchen including knock through to main house ;Chesterford Essex

Barney and the team at Hi Spec managed the conversion of our garage into a Kitchen. This was the first piece of major work we have had done, and we were a bit green. Their single biggest strength, was communication. Throughout the project, Barney and his team talked to us, a lot. When decisions needed to be made they gave options and advice, with sound logic. There were things we had not considered, that Barney and the team pointed out to us in advance and helped us make a sensible decision.

Overall, the standard of work has been excellent and I cannot praise the team enough. They were respectful of our home, a friendly bunch and really flexible. We are over the moon with our kitchen, and we will be using Barney and the team for future work, and I would thoroughly recommend them.

Loft Conversion ;Royston

Hi Spec Design & Build were professional, polite and maintained excellent communication throughout our project. 
We dealt with Barney who is a great people person and he worked through problems with us rather than making decisions himself which we really liked. 
We are very pleased with the end result and the fact that the quote was as we expected was outstanding. We have a much large project to complete at a later date and we will have no hesitation in using them again. 
I’d be happy to provide a reference and photos of our build if you are considering using them for your own project.
