HJ Architect Ltd
Rating: 5 out of 5
Loft Conversion Company in Stepney
HJ Architects is an architectural design studio based in Hampton, London. Established in 2016, we are an emerging practice, working on small carefully crafted projects that have a richness of detail. We have built up a portfolio of well designed residential and commercial projects, including Lawnsmead Cottage and Diamond Cottage, both within the green belt and bordering a conservation area. We emphasise the use of natural light and natural materials in our work, creating buildings and spaces that are elegant, timeless and contribute to their surroundings. The practice works with challenging briefs and solves complex problems with rational and clear design. Our conceptual ideas are developed and presented through sketches, models, drawings and dialogue. We believe good design makes the world a better place and can enrich peoples lives. We work closely with our clients from the outset to develop their brief into an imaginative, pragmatic and cost effective solution that is appropriate to its physical locale and context.

Based on architect recommendation, we contracted Alain on a private basis to produce structural engineering designs for our home renovation. He undertook a site visit and then produced structural designs to support a large number of elements related to new support beams, lintels etc. These have been iterated with the architect and the process has been very smooth. He was very responsive and nice to interact with. Wouldn't hesitate to recommend as a structural engineer for the type of project we undertook (loft conversion, new pitched roof, new openings within walls and ground floor open plan conversion)

Lovely father son business, professional, friendly guys. I asked them to build a plasterboard wall in order to create an extra bedroom in my house, the wall was finished well, within two days and they charged me a very reasonable rate, as a young women in business I find that tradesmen often try to overcharge me but these gentleman did not. They also took a look at leak that had occured which another professional plumber failed to solve and tried to charge me over £200 just to take a look! I have and will book them on a number of other jobs.

Loft Conversion- 5 Dec 2018
Firstly the date of job posting and date of completing is all down to me not being ready with finances!! Secondly, and more importantly, GG Property were the most wonderful and professional bunch of lads you can hope to met. The work was done with such enthusiasm and to such a high level of detail. We could not be happier with the finished job. Thirdly, the great building work aside, GG Property were polite, happy, friendly, punctual and great communicators. All emails answered swiftly and with accurate information. No question was to silly and no concern (this was our first major building working) was to small to be addressed. Finally we are so pleased with work we are awaiting a quote for our bathroom and look forward to getting that job completed!! In short my experience with GG Property was nothing but top quality work and customer service. Any fears of the classic 'cowboy builder' could not be further from the truth; GG Property are a hard working truly lovely bunch and we would highly recommend them.

We are a southwest London Based loft and kitchen extension specialist. Our working area is very small with 90% of our jobs in Wandsworth and any work outside this area is never more than a mile or two away. With over 15 years experience in this area we know inside and out how these properties were built so when it comes to structural alterations you couldn't be in safer hands.

Kitchen Fitting- 7 Jan 2021
My experience with Leszek was entirely positive and I wholeheartedly recommend him. I had recently moved property (converted victorian flat) and required a new kitchen installed, shelves built, radiators replaced, painting throughout and some changes to electrics. The work was undertaken around October 2020. Leszek completed the work to a very high and professional standard and I am really happy with the end result. He was easy to get on with, good natured and commutative which made the whole process easy and less stressful for my first experience in home improvements. Leszek was always happy to answer all my questions and further explain the fine detail from electrics to kitchen installation. When small problems arose, he always had a couple options ready to discuss and called promptly to keep me up to date. The kitchen installation is perfect which also included tiling a backsplash. Lezek built some lovely selves in the recesses either side of my fireplace which look brilliant and very smart. The painter and his work was really professional and speedy. Snagging was dealt with and two neighbours independently and proactively commented that the work was done with minimal disturbance to them. From quote to completion it was all in all an excellent experience!

Questions to ask local loft conversion companies in Stepney

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Stepney?

A local loft conversion company in Stepney will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Stepney should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Stepney loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in Stepney

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Stepney before agreeing to start the work.

Do I need planning permission for a loft conversion in Stepney?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Stepney loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some Stepney loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
