Loft Conversions in South London

The process

Preserving the character of your home is key; by using materials that align with the existing structure, we ensure a harmonious blend between the new space and the original, maintaining continuity in your home’s aesthetic.

We typically manage every aspect of a loft conversion project, covering design, planning, adherence to building regulations, overseeing construction progress, and ensuring the quality of the work. Our in-house team collaborates closely with you and your consultant to create the best possible design within the local planning guidelines.

Throughout the construction, Excel Construction Ltd supervisors and consultants will visit your loft extension site 2-3 times a week to monitor progress and ensure alignment with the work schedule. Our team verifies each weekly stage payment, guaranteeing that you pay only for completed work on site. Additionally, the building inspector will make periodic visits to confirm compliance with building regulations.

Typically, our loft conversions require about 6-8 weeks for completion, although this duration can vary based on the size, complexity, and specifications of your conversion. Beyond providing versatile extra space, a loft conversion significantly boosts your property’s value, should you decide to sell in the future.

Client Testimonials

“Excel were excellent in the whole process of building my loft conversion. From the initial concept of utilising the space I had with drawings right through to the build and then the final product. Very tidy and clean and caused little disruption. Very good.”
Mark Mase
“Excel Construction have carried out a complete refurbishment and modernisation of all services in our house, including a large kitchen space, new bathrooms and loft extension. They are very accomplished builders in all trades and for us they took care of all steel and brick work, plastering, tiling, plumbing, electrics and carpentry, and also helped us deal with suppliers. They are very hard working, considerate, and always worked around our needs, as for most of the time we continued to live in the house during the building work.”
Ramón Nartallo
“Excel Construction were excellent throughout the process of my 2 bedroom loft extension from planning to completion. They gave us ideas we hadn’t even thought about, which made the design flow better and happily took on other construction jobs I needed done in the house. Alex (the owner) kept me in the loop on the smallest decisions and was always available to discuss any questions that I had. I would definitely recommend Excel Construction.”

Lofts Conversions

It is possible to convert your loft under lawful development, also known as permitted development in the UK, this allows certain types of development or changes to be made to a property without the need for specific planning permission. To convert your loft under lawful development, you’ll need to ensure that your project meets the specific criteria:

  1. Property Type: The property must be a house (not a flat) to qualify for permitted development rights for a loft conversion.
  2. Conservation Areas: If your property is situated in a conservation area, permitted development rights might be restricted or might not apply. We will check with your local planning authority to understand the specific regulations for your area.
  3. Leasehold Properties: If your property is leasehold, you generally need to have held the lease for at least 7 years to be eligible for permitted development rights for a loft conversion.
  4. Volume Quota: The size of the loft conversion is typically restricted by a volume quota, which varies based on the type of property:
  • Terraced houses are often limited to 40 cubic meters.
  • Semi-detached and detached houses may be allowed up to 50 cubic meters.
  1. Materials and Design: Ensure that the materials used for the conversion match the existing property to maintain visual harmony. Adherence to the design and aesthetics of the surrounding area is often a requirement.
  2. Compliance with Regulations: Even if your project falls under permitted development, it’s essential to comply with building regulations concerning safety, structure, insulation, fire safety, and other aspects.

We cover South London including: Richmond Upon Thames, Wandsworth, Kingston Upon Thames, Merton, Sutton, Lambeth, Southwark, Croydon, Southwark, Lewisham, Bromley and Bexley

If your loft conversion falls under permitted development rights, the process might be quicker, involving ensuring compliance with the relevant criteria. However, if you need planning permission, the process can take several weeks to a few months, depending on various factors including the complexity of the project and the local planning authority’s workload. We will assist with accurate documentation which can help expedite the process.

The construction phase itself can vary depending on the complexity of the work, structural changes, the materials used, and the number of workers involved. On average, a loft conversion might take anywhere from 6 to 12 weeks for basic conversions, while more extensive projects could take 12 weeks or longer.
