Fitness should be straightforward and practical

Bespoke garden building for home gym

Fitness should be straightforward and practical––everything about packing a suitcase, getting in the vehicle, and driving to the gym is everything but that! In addition to the inconvenience of commuting to a different location merely to work out, there are schedule conflicts and overcrowding issues that may make your day a complete disaster. How can you maintain an active and healthy lifestyle when so many barriers are in your way?

  Many of these concerns may be resolved by owning a home gym. You can squeeze in a brief training session at any time of day and get the benefits of the cumulative impact of several workouts as well. It is just one of the numerous advantages of having a home gym in your garden room that you can take advantage of by scheduling various exercises throughout the day. You may create an awesome fitness asset for you and your family by converting a spare room or just clearing up a little area in the corner.

Personal space is important

When you set up your own home gym, you are establishing a training atmosphere that is both pleasant and private for you and your family. No one will condemn you for taking your time to acquire good postures, discovering how to utilize the equipment to its greatest advantage, and deciding which program and tempo is the best match for your fitness requirements.

Likewise, there are no constraints on what you wear or don't wear during your workout. You may wear anything you choose. You are free to be yourself without the fear of someone taking a photo of you with their phone.

Liberty

With a home gym, you may tailor your workout regimen to meet your specific needs rather than relying on what is readily accessible. We have moved beyond the days of strolling into a gym and discovering that the one piece of equipment you wanted to use was no longer accessible. A home gym provides you with the freedom to customize your workouts in whatever manner you see fit in order to achieve your objectives. Avoid attempting to fit into a pre-determined program at a commercial gym and instead devise your own plan that suits your needs.

Design the building around the equipment

Prepare an equipment layout, including clearance for movement and maintenance. Floor design should account for equipment weights, concentrated loads and any dynamic impact. Discuss impact protection, ventilation, heating and lighting, then review a completed TRJ gym project such as Ashtead or Bishop’s Stortford.

Sources and project-specific guidance

Check the current guidance and the actual project specification. Performance, cost and approval depend on the complete design and site.

PLAN YOUR BUILD WITH TRJ

What should you know before choosing a garden room or annexe?

TRJ Construction Ltd designs and builds SIP garden rooms, granny annexes and house extensions. We work across Hertfordshire, North London, Essex, Buckinghamshire and surrounding areas. The right specification starts with how you will use the building, the site conditions and the services it needs. A home office, a gym and an annexe for independent living have different requirements.

Which type of building suits your project?

Choose the building around its intended use. A garden room can provide a separate place to work, exercise or relax. An annexe needs a layout and facilities suitable for its proposed residential use. A house extension changes the existing home and needs its structure and services considered together.

What SIP specification does TRJ use?

Our published specification includes 125 mm structural insulated wall panels and 150 mm SIP panels for roofs and bases. The final design must account for the particular building, structural loads, moisture control, ventilation and finishes. Panel thickness alone does not establish the performance of the completed building.

  • 125 mm: the wall-panel specification described in our company information.
  • 150 mm: the roof and base panel specification described there.
  • Since 2012: TRJ Construction Ltd has been led by Costi Tiseanu, whose construction experience spans more than 25 years.

Read Costi’s experience and TRJ’s specification, or see how our buildings are constructed. These are details about our work, rather than industry-wide performance claims.

How do you start a garden-building project?

  1. Describe the use. Tell us whether the building is for work, exercise, hobbies or living accommodation.
  2. Share the site information. Send photographs, approximate dimensions, access details and any existing drawings.
  3. Review the requirements. Discuss planning, building control, foundations, drainage and electrical connections.
  4. Agree the specification. Confirm the layout, materials, fit-out and the items included in the quotation before work begins.

Our completed projects show real examples. Where a project was built by TRJ for Garden Spaces, the case study identifies that relationship.

What questions do clients ask?

Can a garden room be used all year round?

Yes, a garden room can be designed for year-round use. The specification needs suitable insulation, heating, ventilation and moisture control. We discuss the intended use and site conditions before agreeing the build.

Can TRJ include a bathroom or kitchenette?

Yes. TRJ builds garden rooms and annexes with bathrooms and kitchen facilities. The layout, drainage route, water supply, electrical requirements and applicable approvals need to be assessed for the site.

Does every garden room need planning permission?

No single answer applies to every site. Some outbuildings may qualify as permitted development, subject to limits and conditions. Location, dimensions, previous permissions and intended use matter. Living accommodation needs particular care. Check the proposal with the local planning authority before building.

How much will my building cost?

The price depends on floor area, access, foundations, glazing, services and interior finishes. Use our annexe cost guide as a starting point, then request a quotation for your site and agreed specification.
