What we build in Chislehurst and Bromley

Chislehurst has some of the largest detached houses in South East London, set on generous plots, while Bromley and Sidcup have plenty of 1930s semis and detached homes. That means bigger projects: wraparound and two-storey extensions, large loft conversions, and full refurbishments that change how a house works.

  • Two-storey and wraparound extensions
  • Large loft conversions
  • Whole-house refurbishments
  • Kitchen extensions and open-plan living
  • Garage conversions
  • Structural alterations

Bigger houses, bigger projects

On a detached house, a single-storey rear extension of up to 4 metres can often go ahead under permitted development, and up to 8 metres with prior approval. Two-storey and side extensions usually need planning permission, and conservation areas add another layer of checks.

Our Wimbledon whole-house project shows what a bigger job involves: a full refurbishment, a rear and side extension, a dormer loft and a new garden, delivered in 20 weeks on site.

GLB has been a star find for me. The whole experience of refurbishing our property was as close to being a pleasure as building work can be! Geraldo is a super nice guy and a very good listener; he's patient and remains a calming presence even when the inevitable unexpected snag crops up.
Geraldo runs a tight ship and his team are of the same high calibre—professional, efficient, and very tidy. As a property investor, I was anxious about finding a replacement for my previous builder of many years, but GLB has filled those shoes seamlessly. His prices are very competitive, the work is outstanding, and most importantly, he delivered exactly what was promised on time. Highly recommended.

Geraldo and his team recently completed a full fit-out of our flat that we purchased in terrible condition. It included a complex relocation of the kitchen and boiler to create an additional bedroom and create an open plan kitchen, diner and lounge. From start to finish, Geraldo was a true professional. His attention to detail is second to none—not just in the construction, but in the administration as well. Without even being asked, he provided a complete handover pack including Building Regs, Gas Safe, and Electrical certificates, along with all appliance warranties. We used our local council for Buildings Regulations and he deftly managed all their requirements, easing the worry for us tremendously.

He was incredibly helpful during the pre-construction phase, providing all the necessary documentation to satisfy our freeholder’s requirements. Throughout the build, he suggested several clever ways to save on costs while actually improving the design and functionality of the space. He is a 'communication is key' professional who always answers his phone and solves problems with total patience and clarity. Even after the project was finished, he went out of his way to help with a minor follow-up issue. I wouldn’t dream of using anyone else for future work.

The team did an excellent job on my refurbishment! This included installing engineered wood flooring throughout, new kitchen, new bathrooms (2+1 separate WC), underfloor heating, plastering plus many more jobs. They kept me updated of progress all along the way especially when I was away and minimised the pain of doing work while also living in the house. My first point of call if I ever needed something done.

GLB has worked with us for over two years, firstly doing renovations and then little “bits & bobs”. Outstanding quality, service and staying with you when others “ride off into the sunset”. Geraldo and the team come with highest recommendations and they are a true delight to work with….a firm you can trust for the long haul…no hesitations in adding a five star recommendation….and I am difficult.

Geraldo built an extension to my flat, a new kitch and toilet/shower room. I am very pleased with it. He and his team were expert, informed, attentive to detail, good timekeepers - and friendly. I recommend them

GLB Construction was great to work with from start to finish. The team was professional, easy to communicate with, and paid close attention to the details. The work was done on time and turned out exactly as expected. Overall it was a smooth experience and I’d definitely recommend GLB Construction to anyone looking for reliable construction work.

We had work done a while back so we can say that Geraldo’s work has stood the test of time ..no cheap materials no shortcuts…if something isnt a good idea structurally.. he will let you know…he has a very good understanding of the client’s vision..and does not shy away from starting all over if something doesnt feel right..great work

Mehreen A.Google review

"Top-notch service! I hired them for a parquet installation and I couldn't be happier. The guy running the business is young, energetic, and clearly a master of his craft. It’s rare to find such high-quality woodwork combined with great communication and fair, competitive prices in London. If you need a specialist for your house renovation, look no further!"
